Overview OVERVIEW _____________________________________________ Welcome to the Shure P4800 System Processor software guide. This document will help you understand how the P4800 functions as you learn to use the software interface. The hardware stands alone as both a front-end and back-end system processor that can be externally controlled by a simple end-user interface. The software is the tool that configures the device's internal signal routing and audio processing.
Overview Modular Signal Processors Each signal processing module is encapsulated in a graphic block that you can manipulate with the mouse. You can access the processor settings by double-clicking on the block to open its parameter window. Settings can be saved and recalled from the computer, and copied between similar modules. Processor settings can also be synchronized via the link feature. The P4800 includes the following selection of signal processor modules.
Overview Interface Modes The Interface features two primary modes of operation: Design Mode and Live Mode. This provides you with the option of creating configurations for the System Processor regardless of whether or not the computer is connected to the device. There are certain functions that are specific to each mode, which are explained throughout the manual. Design Mode When you launch the application, you always begin in Design Mode.
Overview Main Window This window, shown below in figure 1, is your primary workspace in the software interface. You can size it proportionally larger, or maximize it to take up your entire screen. Closing this window exits the application. Figure 1 − Main Window 1. Title Bar The information on the title bar of this window changes depending upon the operating mode. In Design Mode the title bar reads, “P4800: Offline,” and indicates the default security level.
Overview 3. Control Bar This section of the window changes in appearance and function depending upon the operating mode. When you are in Live Mode the control bar emulates the LED meters on the front panel of the hardware, as pictured below in figure 3. Figure 3 − Control Bar in Live Mode The meters can be toggled on and off by clicking on them with the left mouse button, or by selecting [View > Enable I/O Meters] from the main menu.
Overview 11. Signal Flow Diagram The signal flow diagram depicts how audio signals pass through the various processors in the hardware. It shows audio signal flow as moving from left to right along the input and output channel strips. Each channel strip contains fixed components for adjusting gain and mixing channels. They also contain a series of empty slots for adding different types of processing. 12.
Overview 21. Output Gain Double-clicking this block opens the Output Gain window, which provides you with -10dBV/+4dBu scaling options, channel mute, polarity control, a –20dB pad, and a +/-30dB fader for each output channel. This is the final stage of the System Processor’s gain structure. This is also where you can designate a custom name for your output channel that pertains to your particular setup. 22. Output Channel Label This displays the channel label designated in the Output Gain window. 23.
Start-Up Guide START-UP GUIDE ________________________________________ The start-up guide covers the basic steps required for complete set up of the System Processor. Before attempting to follow these instructions, you should familiarize yourself with the Overview section, which introduces some basic features of the software interface.
Start-Up Guide 4. Go Live with the System Processor a) Click the [Live Mode] button on the control bar of the main window. b) The Select Devices dialog opens, listing all available devices, as pictured in figure 7 on the right. The ID number indicated on the left side of the list is set with DIP switches on the back of the device. c) Select the System Processor unit you will be working with and click [Connect].
Start-Up Guide Create a Signal Flow Template This can be done in either Live Mode or Design Mode. When you are storing multiple presets in the System Processor, you will save considerable time by creating a signal flow template that contains the attributes that will be common among them. This template can then be recalled from the device or opened from a scene file on PC, revised as necessary, then stored in the device each time as a new preset. 1.
Start-Up Guide 9. Name the Preset Click once with the left mouse button anywhere in the information box in the center of the control bar to open the Preset Information dialog, as pictured on the right in figure 9. Enter a name for the preset, up to 15 characters long, and a description, then click [OK]. For more information, refer to the Naming a Preset or Scene File section on page 19. Figure 9 − Preset Information Dialog 10.
Creating a Configuration CREATING A CONFIGURATION ____________________________ A configuration is a unique combination of signal routing connections, the selection and placement of modular processors, and processor settings. You create the configuration in the signal flow diagram of the main window, and save it either as a preset in the device, a scene file on the computer, or both.
Creating a Configuration Matrix Mixer Once a signal has been routed to the mix point of an output channel strip, it enters the matrix mixer stage of the gain structure. Double-click on any mix block to open the Matrix Mixer processor window, which displays a pane for each output channel strip. When crossovers are placed over multiple output channels, the mixer panes for those channels will combine to reflect that configuration.
Creating a Configuration Signal Routing The System Processor allows you to route signal from each of the four inputs to any or all of the eight outputs. In order for signal to pass from the input channel strips to the output channel strips, it must be routed through the Matrix Mixer. You can connect inputs to outputs using any of the methods described below.
Creating a Configuration Naming a Preset or Scene File Since you can store up to 128 different presets in the System Processor, it can be helpful to differentiate them with a name and a brief description. The information box in the center of the control bar of the main window displays these details, as pictured below in figure 11.
Creating a Configuration Adding Processors Each channel strip has a row of empty slots that can contain any of the modular processor blocks. Except for crossovers and splitters, there are no restrictions on where processors can be placed on the signal flow diagram, or how many times you can use a given processor on the same channel strip. Empty slots between processors do not affect the signal flow, so blocks do not have to be adjacent on the channel strips.
Creating a Configuration To add multiple processor blocks: 1. CTRL+Click to select multiple empty slots. 2. Use the right-click contextual menu to place the same type of processor in every selected slot. - OR 3. Use the [Processor>Add] option on the main menu bar. Stereo Processors Stereo processors are placed in the signal flow diagram in much the same way as the other modular processor blocks. However, each of the stereo channels appears as a separate block.
Creating a Configuration Crossovers and Splitters Since they are output processors, crossovers can only be placed on output channel strips. They can be added to output strips like any other processor block, but you must take into account the following: § A crossover extends downward to span the specified number of outputs, so you must select a channel strip that has enough outputs below it. § A crossover block can only span consecutive outputs. § Crossovers cannot overlap on any output strips.
Creating a Configuration DSP Usage Meters These meters, located at the bottom of the main window, indicate the amount of DSP resources and delay memory utilized by the current configuration. Knowing the amount of DSP resources and delay memory you have left enables you to manage your processor choices efficiently.
Creating a Configuration § Add processors to the input side of the matrix mixer, instead of the output side, if possible. § Remove processors from any unused channels. § Use splitters to consolidate identical signal processing on multiple output channels. § Use a PEQ10 instead of a GEQ30. In most cases, you will not use all thirty filters on the GEQ30, and the PEQ10 uses less than half as much DSP. § Replace DFRs with parametric EQs after you are finished ringing out the system.
Creating a Configuration Linking You can link multiple processor blocks of the same type in order to control them as one. Changes made in the processor parameter window of any block in a link group will simultaneously change the settings of every other block in that group. There are a few activities, however, that will still function independently on linked blocks: § Delete, Copy, Cut and Paste, § Moving the block to a different slot or channel strip, § Naming the processor parameter window.
Creating a Configuration Adding to a Link Group Processor blocks can be added to an existing link group, if they are the exact same type of processor and they are currently unlinked. Any processor added to a link group will inherit the group’s current settings. To add blocks to an existing link group: 1. Click to select a processor block, or CTRL+Click to select multiple blocks. 2. Select [Processor>Link>Add To] from the main menu, or [Link>Add To] from the right-click contextual menu. 3.
Saving a Configuration SAVING A CONFIGURATION _______________________________ After you create a configuration, you can save it to either the computer as a scene file, or to the device as a preset, depending on whether or not you are connected to the P4800. When you are in Live Mode, the configuration you are creating is written directly to the current live preset. You can save it to the PC at any time by clicking the [Save As] button on the control bar of the main window.
Saving a Configuration Preset Management The System Processor can store at least sixteen and up to one hundred and twenty-eight presets in its device memory, depending upon their complexity. Once presets are stored in the device, they can be renamed, deleted, or backed up as a set. Store a Preset in the Device When you are connected to the device, in Design Mode you can store new signal flow configurations to the device as presets, or open existing scene files and store them to the device.
Saving a Configuration Rename a Preset After you have stored a preset in the device, you can change its name and description in Live Mode. To rename a preset: 1. Click on the [Live Mode] button on the control bar. 2. Select the preset you wish to rename from the pull-down menu in the information box on the control bar. 3. The main window will enter preview mode for the selected preset. 4. Click the [Load] button on the control bar to make it the live preset. 5.
Saving a Configuration Device Backup You can backup all presets stored in the device to a single archive, and restore this backup set to the device at a later date. You must be in Design Mode to perform or restore a backup. To backup all presets in the device: 1. Click on the [Design Mode] button on the control bar. 2. Select [File>Backup Device] from the main menu. 3. The Select Devices dialog will appear. 4. Select from the list of available devices and click [Connect]. 5.
Processor Features PROCESSOR FEATURES__________________________________ This section describes software features that are common among many of the processor parameter windows. For features specific to the individual processors, refer to the Fixed Processors section on page 34 and the Modular Processors section on page 40. Faders Faders appear in many of the processor windows, as in the example pictured below in figure 23, below on the right.
Processor Features Spin Buttons Spin buttons appear to the left of all value boxes. They provide a convenient way to increment the setting without having to type in a specific value. To increment the value with spin buttons: § Click on the up or down spin button to increment the level +/–0.5 dB. § Click and hold on a spin button to scroll the level up or down. As you hold longer, the scrolling will accelerate.
Processor Features Snapshots The snapshot feature is available in any processor parameter window that has a response curve or transfer curve graph. It allows you to capture an image of the current curve, then display it for reference purposes as you revise the processor settings. The processor remembers this snapshot until you take a new one in the same processor window, or quit the application.
Fixed Processors FIXED PROCESSORS _____________________________________ These processors make up the three different stages of the System Processor’s Gain Structure (see page 16 for more on this topic). They are referred to as fixed processors because the gain and mix blocks in the signal flow diagram cannot be moved or deleted. Input Gain The Input Gain processor contains individual controls for all four input channels.
Fixed Processors Gain Controls Use these controls to adjust the signal level of each input channel. First select the fader knob, then adjust the level with the mouse, arrow keys, or specify a level in the value box. For complete instructions on their operation, see the Faders section on page 31. The adjustment range is from +30dB to –30dB, and the default setting is 0dB, or unity gain.
Fixed Processors Matrix Mixer The Matrix Mixer processor contains controls for mix point connections in the signal flow diagram, organized under separate window tabs for each output mix point. Double-click on any mix block to open this window, as pictured below in figure 28. Figure 28 − Matrix Mixer Window Window Tabs The window opens focused on the output pane for the mix block that you double-clicked. Click on any tab to access controls for a different output mix point.
Fixed Processors Input Controls Click this button to activate a connection from the corresponding input channel mix point. Controls for inactive inputs appear faded out. The default setting is inactive. Input Selector Click this button to activate a connection from the corresponding input channel mix point. Controls for inactive inputs appear faded out. The default setting is inactive. Connection Activated Connection Inactive Signal Polarity Click this button to invert the polarity of the signal.
Fixed Processors Output Gain The Output Gain processor contains individual controls for all eight output channels. Double-click on the gain block at the right end of any output channel strip to open this window, as pictured below in figure 30. Figure 30 − Output Gain Window Scaling Options Use these buttons to scale each input channel to match the output level of the equipment in line before the System Processor. Click to toggle between -10dBV or +4dBu levels. The default setting is +4dBu.
Fixed Processors Gain Controls Use these controls to adjust the signal level of each output channel. First select the fader knob, then adjust the level with the mouse, arrow keys, or specify a level in the value box. For complete instructions on their operation, see Faders section on page 31. The adjustment range is from +30dB to –30dB, and the default setting is 0dB, or unity gain. Output Pad Click this button to attenuate the signal output by –20dB. The default setting is inactive.
Modular Processors MODULAR PROCESSORS _________________________________ This section describes the features and controls specific to each of the processor block parameter windows. In some cases, several processor blocks share nearly identical controls, such as the downward expander and gate. In these instances, the processors are described as a group, using a single parameter window as the illustrated example.
Modular Processors Transfer Curve Graph The transfer curve graph displays the threshold level and compression ratio settings as graphical elements that you can position with the mouse. The resulting transfer curve represents the change in the signal output level. Maximum Gain Line The greatest amount that the AGC will boost the signal is +12dB, as indicated by the maximum gain line.
Modular Processors Threshold This indicates the level the signal gain must reach before the processor increases it. Signal levels below the threshold are passed through the processor at unity gain. You can change the value by clicking on the spin buttons, typing in a specific value, or using the threshold slider above the transfer curve graph. The available range of values is from –60VU to +20VU in 0.5VU increments, with a default value of 0VU.
Modular Processors Compressor/Limiter Compressors and limiters reduce the output level of the signal relative to the input level, once the input level exceeds a certain threshold. The System Processor provides the following types of compressors and limiters: Block Name Description § COMP § SFT COMP Compressor § LIM § SFT LIM Limiter § § § § ST COMP ST SFT COMP ST LIM ST SFT LIM § PEAK LIM Soft Knee Compressor Soft Knee Limiter Same as above; for use on two channels that comprise a stereo pair.
Modular Processors The following types of processors are available in both limiters and compressors. § Soft Knee – These processors provides a gradual transition from uncompressed signal to compressed signal. These processors consume a higher percentage of total DSP than those without the soft knee option. § Stereo – These processors allows you to preserve a stereo image by placing two blocks that function as a single processor on two different channels.
Modular Processors Threshold Exceeded Indicator This indicator appears lighted in yellow when the input signal to the processor block exceeds the specified threshold. Signal level has exceeded the threshold Signal level has not reached the threshold Threshold This indicates the gain level the signal must reach before the processor begins compressing it. You can change the value by clicking on the spin buttons, typing in a specific value, or using the threshold slider above the transfer curve graph.
Modular Processors Bypass Click to pass signal through without the effect of the processor. When bypass is active, the button appears lighted in red. The default setting is inactive. When bypass is active in the Peak Stop Limier, the 1 ms of delay is not bypassed. Bypass active Bypass inactive Snapshot This feature allows you to freeze an image of the current response curve by clicking the [Take] button and then display it in the background for comparison by clicking the [Show] button.
Modular Processors Crossover/Splitter Crossovers and splitters divide one input signal into multiple output signals. Crossovers divide the frequency spectrum of the input signal into multiple bands, then output each band to a separate channel. Splitters simply distribute the input signal across multiple output channels.
Modular Processors Response Plotter This area of the window graphically displays the pass band filters and crossover points, which you can manipulate by clicking and dragging with the mouse. Pass Bands Each band has a corner handle on either side that you can drag left and right to individually adjust the upper and lower corner frequencies. There is also a gain handle in the center of each band that you can drag up and down to adjust the output level of the pass band.
Modular Processors Default Click this button to reset the processor to its system default settings. Mute Click this button to mute the output channel. When mute is active, the button appears lighted in red The default setting is inactive. Mute activated Mute inactive Polarity Click this button to invert the polarity of the signal entering the output channel strip. The default setting is normal polarity.
Modular Processors Note: Using a 12dB/oct filter type in adjacent bands will create a notch at the crossover frequency if the outputs are summed. When aligning loudspeakers, take care that the acoustic response does not display this notch. If necessary, use the polarity button to invert the polarity of one of the bands. Upper Corner Freq This indicates the frequency setting of the upper corner of the pass band.
Modular Processors Cut and Shelf Filters The cut and shelf filters are a type of parametric EQ that boost or cut the overall high and low frequency characteristics of a system, and roll off the high and low end of the frequency spectrum. Block Name § Description CUT/SHELF High and Low Cut/High and Low Shelf Filters Figure 38 − CUT/SHELF Window Function Use this processor when you need to combine cut filters with broad-spectrum high and low-end room equalization.
Modular Processors Response Graph This curve is a graphical representation of the combined results of the filter handles in the response plotter. Note: The curve does not reflect the accumulated affect of multiple processor blocks in the signal path. Cut Filters Cut filters appear as handles at the bottom edge of the response plotter, with dashed vertical lines extending along their center frequencies. Their default frequency setting is "OUT," and the default type is 6dB/Butterworth.
Modular Processors Snapshot This feature allows you to freeze an image of the current response curve by clicking the [Take] button and then display it in the background for comparison by clicking the [Show] button. The [Show] button appears lighted in green when the snapshot is displayed. Refer to the Snapshots section on page 33. Importing ASCII Files See page 74 for a description of how to import data into the graph, using SIA Smaart and Gold Line TEF into the response graph.
Modular Processors Delay The delay processor temporarily stores the signal in delay memory, then passes it on after the specified interval has elapsed.
Modular Processors Distance Use this control to specify the delay by distance. The range of values varies, depending on the maximum delay time, but the default is always zero. Select the appropriate unit of measure with the radio buttons to the right of the control. When English units are selected, you can choose between inches or feet. When Metric units are selected, distance is indicated in meters. The default value is inches.
Modular Processors Digital Feedback Reducer (DFR) The DFR uses Shure's patented Adaptive Notch Filter algorithm to automatically detect feedback and deploy narrow-band notch filters.
Modular Processors Depth This indicates the gain reduction of the selected filter. The range of available gain values is between 0db and –18dB in 0.5dB increments, with a default setting of 0dB. Type This indicates the bandwidth type of the selected filter. Select High Q or Low Q from the pull-down menu. Low Q is the default value. Feedback Filters The feedback filters controls appear as a row of LED-style indicators.
Modular Processors Basic DFR Setup There are two basic ways in which to set-up the DFR to reduce feedback; the Ring-Out Method and the Insurance Policy Method, as described below. Each is valid for different situations. Note: § § 1. 2. 3. 4. 5. The DFR (or any other notch filter system) helps reduce feedback, but cannot entirely eliminate it. In a typical system, you reach a point of "diminishing returns" after 4 to 8 notch filters are set.
Modular Processors Filter Allocation The DFR uses two methods of filter allocation, as described below. § Fixed – You can manually specify these notch positions or designate them as fixed after the DFR has automatically deployed a dynamic filter. They remain stationary regardless of newly detected feedback frequencies. However, if the DFR detects additional feedback at that position, a dynamic filter will deploy to increase the notch depth. § Dynamic – The notch position and depth are completely automatic.
Modular Processors Adding, Modifying, and Removing Filters 1. 2. 3. To manually deploy or modify a fixed filter notch: Click to select an active fixed filter (highlighted in yellow) or, to activate a new filter, select the filter to the immediate right of the last active filter. Adjust the frequency, depth, and type as necessary. You will see the changes reflected in the response graph. Note: 1. 2. 3. 4. You can only select an active filter or the next adjacent inactive filter, from left to right.
Modular Processors Gate/Downward Expander The gate and downward expander reduce the output level of the signal, relative to the input level, once the input level drops below a certain threshold. Block Name § § Description DOWN EXP Downward Expander GATE Gate Figure 45 − DOWN EXP Window Function Use these processors to reduce or eliminate unwanted background noise. The gate mutes the input signal once it falls below a certain threshold.
Modular Processors Transfer Curve Meter When you are in Live Mode, this meter depicts the signal's input level and relative output level, so you can monitor the processor's effect on the current program material. This feature can be toggled off and on by selecting the [Options>Transfer Curve Meter] menu option. Its default status is on. Note: You may experience reduced software performance if you have a large number of meters active in the System Processor software.
Modular Processors Attack This indicates how much time the processor waits after the input signal gain exceeds the threshold before returning to unity gain. The available values are from 1ms to 200ms, with a default value of 2ms for the gate and 20ms for the downward expander. Decay This indicates how much time the processor takes to reach the specified gain reduction. You can change the value by clicking on the spin buttons or typing in a specific value.
Modular Processors Graphic Equalizer Graphic equalizers distribute a fixed set of broadband, constant-Q filters across the frequency spectrum, each with individual boost/cut controls. The System Processor provides the following types of graphic equalizers: Block Name Description § § GEQ10 GEQ30 10 Band Graphic Equalizer 30 Band Graphic Equalizer Figure 46 − GEQ10 Window Function Use this processor for convenient broadband room equalization.
Modular Processors Frequency This indicates the current frequency band that you are adjusting. You can select a different frequency band by clicking on the spin buttons. The default selection is the lowest frequency band. Gain This indicates the current gain setting of the selected frequency band. The range of available gain values is between –18dB and +12dB in 0.5dB increments, with a default setting of 0dB. You can change the value using the conventions explained in the Faders section on page 31.
Modular Processors Parametric Equalizer Parametric equalizers allow you to specify the placement, type and bandwidth of multiple filters anywhere in the frequency spectrum between 25Hz and 20kHz. The System Processor provides the following types of parametric equalizers: Block Name Description § § § § PEQ3 PEQ5 PEQ7 PEQ10 These processors provide peak/notch filters only.
Modular Processors Parameter Window Features This section explains the features and parameter controls of the parametric equalizer processors using the PEQ3+CS as the example, as pictured in figure 47 on the previous page. The features of the other parametric equalizers vary only in the number of bands and the availability of the cut/shelf filters. Response Plotter This area of the parameter window is where you place and adjust parametric filters.
Modular Processors Width /Slope/Type This control changes depending on the type of filter currently in selection, as listed below. For a cut filter, you have two slopes to choose from the pull-down menu. When a peak/notch filter is selected, you can use the pull-down menu of preset values, or specify the width within a thousandth of an octave by typing in a value. There are no settings in this control for shelf filters.
Modular Processors Working with Filters When you initially open the parameter window of a parametric EQ, there are no peak/notch filters in the response plotter. Add filter points as you need them, up to the maximum number available for the selected processor block. 1. 2. 1. 2. 3. 4. 5. To add a new filter point: Click the [New] button. A filter point appears at 0dB with a default frequency value of 1kHz and a bandwidth of 2/3 octave.
Modular Processors Keyboard Controls You can use the following keyboard controls to make fine adjustments to the currently selected filter. Keystroke Result ← → Increases frequency by one screen pixel ↑ Increases gain by 0.5 dB ↓ Decreases gain by 0.
Modular Processors Ducker The ducker provides an easy way to use the P4800 in an audio system that requires paging. When a paging signal is present, the ducker attenuates or "ducks" other signals. § Block Name Description DUCK Ducker Function Drag and drop the ducker onto an input strip to designate that input as the paging signal. When the paging signal exceeds the threshold, the ducker attenuates all other signals present at each matrix mixer point to which it is routed.
Modular Processors Parameter Window Features Transfer Curve Graph The transfer curve graph displays the threshold level as a graphical element that you can position with the mouse. Transfer Curve Meter In the Live Mode, this meter depicts the paging signal's input level, so you can set the threshold above ambient noise. This feature can be toggled off and on by selecting the [Options>Transfer Curve] menu option. Its default status is on.
Modular Processors Attack This controls the amount of time it takes the processor to fully reduce the ducked signals’ gain, once the paging signal crosses the threshold. You can change the attack time by clicking on the spin buttons or by typing in a specific value. The range of available values is from 1 to 5000 ms. Hold This controls the amount of time the processor continues to attenuate the ducked signals once the paging signal has dropped back below the threshold.
Modular Processors Importing ASCII Files from SIA-Smaart or Gold Line TEF Software Graphic equalizer, parametric equalizer, and cut/shelf windows can display data contained in an ASCII file exported from either an SIA-Smaart transfer function measurement or a Gold Line TEF TDS measurement. Function Use the ASCII file import feature to display frequency vs. magnitude information measured in Smaart or TEF. By inverting the data, you can use the display as a visual guide when setting EQ parameters.
Modular Processors Parameter Window Features Import Click this button to import ASCII files from either Smaart or TEF. When the [Open File] window appears, select the file you wish to import. The data from the imported file will be displayed in the Response Graph. When a TEF TDS file is imported, the average magnitude value is plotted at 0 dB and all other magnitude values are biased accordingly. By default, Smaart transfer function files are not offset.
Control Pins CONTROL PINS__________________________________________ The pin connectors on the back of the System Processor provide options for external control of the device and logic output. You can connect external control hardware to the control input pins, such as an AMX, Crestron, or a custom wall panel. This type of simple hardware interface provides end users with a means to switch between presets, mute channels, or adjust gain without the need for a computer.
Control Pins The Control Pins Window The Control Pins window is an interface for both configuring control pins globally at the device level, and assigning processors to controllers specifically for each preset. Access this window by selecting the [Devices>Control Pins Configuration] menu command from the main window. Configuration Views The Control Pins window has two configuration views: Control In and Logic Out.
Control Pins Note: There are restrictions as to which encoding types may be used in combination with the number of presets that you specify. Refer to the Preset Encoding Types section on page 81 for more information. # Presets Specify here the number of presets in the device that will be addressed by external hardware in the given configuration view. The range of values is from 0 to 128, with a default value of zero. Encoding Type Specify here the type of encoding you will be using for preset control.
Control Pins Connection Blocks The number of connection blocks that appear in the window depends on how many pins are available after you have specified preset control. Allocate different controllers or logic output to a pin connection by making a selection from the pull-down menu on the right-hand side of the block. The pin connection(s) can be alternately enabled and disabled by clicking on the block with the left mouse button, or selecting [Disable] from the pull-down menu.
Control Pins Gains (Control Input Only) Gain can be externally controlled by a 100k potentiometer. Directly under any connection block that is assigned a pot controller is a gain scale, indicated by a blue bar. You can specify the range within which the pot adjusts the level from –30B to +30dB maximum. The default range is –30dB to 0dB. Figure 53, below on the left, illustrates the gain mapping checkboxes. To edit the gain range adjusted by the pot: 1.

Use this template file as basis for each preset that you create for the device. Mapping an Existing Preset or Scene File Existing presets can be mapped after they have been stored to the device and scene files can be mapped after they have been saved to PC. To map an existing preset in Live Mode: 1. Go live with the device. 2. Select a preset to map. 3.
Security SECURITY ______________________________________________ Security is an optional feature that allows the installer, or other security administrator, to restrict the end user's access to System Processor settings via the computer. The administrator is the individual who sets the device's password and the access level at which it will operate after it is installed.
Security Set the User Access Level Once you create a password, the device is automatically set to user access level one. If access to the device must be further restricted, set the device to the appropriate access level. 1. 2. 3. 4. 5. 6. 7. 8. To set the user access level: Go into Live Mode with the device. Select [Security>Level] from the main menu. The Password Required dialog appears, as pictured to the right in figure 59. Enter the password and click [OK].
Security Removing Security Device security can be completely reset to default status so that others may set an administrator password and define user access levels. To remove password protection: 1. Go into Live Mode with the device. 2. Select [Security>Set Password] from the main menu. 3. The Set Password dialog appears, as pictured in figure 61, on the previous page. 4. Type the current password in the [Old Password] field and press ENTER or Click [OK]. 5.
Printing PRINTING REPORTS _____________________________________ The P4800 software provides printed reports to document all of the presets and settings that are stored in the device.
