How to Operate Your Instrument How to Operate Your Instrument Overview The audio monitor uses a flexible, tiled display and can display four tiles at one time. Each tile can display a different measurement, effectively creating four independent instruments. To enable the tiles to function independently, most of the controls affect only one tile at a time. The tile that is currently being controlled is considered the active tile and it is indicated on the display by a light-blue outline around the tile.
How to Operate Your Instrument The audio monitor can also display one tile at a time. To select a display to be shown in full-screen mode, touch the tile so that it is highlighted in blue and then press the DISPLAY button. The audio monitor can display measurements in multiple tiles simultaneously. For example, you can display four Status screens at one time. You cannot display more than one tile of type Bars, Phase and Surround. These display types can appear in only one tile at a time.
How to Operate Your Instrument Controlling the Audio Monitor There are three ways to control the audio monitor. You can use the buttons on the front panel, you can use the touchable settings on the display, and you can use the menus that appear on the display (including the Main pop-up menu). Use the front panel buttons to select frequently used displays, to select modes that affect multiple displays, and to change values using the large knob.
How to Operate Your Instrument View All Available Measurements Using the Main Menu Press the front-panel MAIN button to open the Main menu and display a pop-up menu showing all available measurements. Note that this pop-up menu is the only place you can access some measurements. You can use the Main menu to perform the following tasks: Printing the Error Log or the on-screen display. Configuring instrument settings. Accessing the shutdown and quiet modes from the Standby menu.
How to Operate Your Instrument 2. To return to four-tile view, press the DISPLAY button again. Front Panel Controls The audio monitor uses a touch-panel display, front-panel knobs, and buttons to control the monitor.

Alarms Alarms The audio monitor can be set up to automatically check parameters when they exceed limits, and report them as alarms. The procedures that follow describe how to configure response types for individual alarms, how to enable them, and how to monitor them. The Menu Diagrams section in this manual shows a map of the Alarm Setup Menu. Configuring Alarms Alarms may need to be configured before you use them.
Alarms 3. For each alarm that is listed in the table, touch the box under each response that you want to enable for that alarm. An X will appear in the box when that response is enabled. To disable a response, touch the box to clear the X. 4. Press Save and Close when you are finished. 5. Repeat the above steps to configure as many types of alarms as you want. To Enable or Suspend Global Alarm Responses 1. To enable the alarms you have configured, check the Enable Alarms box on the Alarm Setup menu.
Alarms To Set All Alarms to a Single Reporting Method 1. From the Main button menu, press Config > Alarm Setup > Set All Alarms to This Mask. 2. Check (or clear) the boxes of the masks you want to enable (or disable). 3. Press Save and Close. This sets alarms for all alarm categories to the setting on the global mask. 4. To globally enable alarms, check the box next to Enable Alarms on the Alarm Setup menu.
Alarms To Enable Audio Alarms The channels for which you enable alarms trigger your previously defined alarm responses. 1. Press the SETTINGS button on the front panel and then press IO Bar and Config. 2. Press the soft key of the Audio I/O type that you want to configure. 3. Check (or clear) the boxes in the Current Bar Configuration menu located at the bottom of the screen. This will enable (or disable) the alarm for the specified input. 4.
Alarms To Set Limits or Qualifications Some audio alarms also require setting a threshold or condition that triggers the alarm. 1. From the SETTINGS button menu, press Digital Display. The menu shown at right will appear. 2. To set a value, press a soft key, such as # samples for clip. Turn the general knob to change this value. For each value selection, set the following alarm levels that trigger an alarm when exceeded: Clip Samples: Number of consecutive samples at the all-high level.
Alarms Indicator Description Error (red) Alarm triggered now. NOTE. To monitor alarms remotely, use a PC to monitor SNMP traps over the Ethernet port (the PC must have SNMP trap service installed). Before SNMP traps can be sent, you must enable and configure the instrument for SNMP control using the Network Settings submenu of the CONFIG menu. Logging The audio monitor contains two log files: diagnostics and events.
Selecting and Monitoring Audio Selecting and Monitoring Audio The audio monitor provides several methods to monitor audio signals. You can measure levels, monitor phase, and display phase correlation. You can specify meter ballistics and scales, set the Test and Peak Program indicator levels, and specify how phase is displayed. NOTE. Depending on which audio option is present, different audio capabilities will be available.
Selecting and Monitoring Audio 3. Select one of the displayed audio input options. NOTE. The available selections depend on the installed audio option. Selecting Follows Video selects the Video to audio mapping set in the Video to Audio Map submenu. Checking Audio Level & Phase With the Bars display, level meters are vertical bar graphs where the height of the bar indicates the amplitude of the audio program in the corresponding input channel.
Selecting and Monitoring Audio Check Audio Phase 1. Press the PHASE button on the front panel. 2. Touch Style and choose Soundstage or X-Y orientation. 3. Touch Pair and select the Phase Pair to be displayed. 4. Check for Phase correlation of the signals, noting the following: Phase correlation meters are located under the appropriate bars and one is duplicated under the phase display. For highly correlated signals, the diamond will be green. For identically correlated signals, the diamond will be white.
Selecting and Monitoring Audio Soundstage plots the two channels at 45 degree angles, with the mono combination appearing on the vertical axis—like a left-right image in a studio. X-Y plots left-channel data on the vertical axis and right channel data on the horizontal axis, emulating the X-Y display of an oscilloscope. The response time of the correlation meters can be set from the CONFIG menu. The choices are shown in the following table.
Selecting and Monitoring Audio 5. Use the level bar display to monitor level control. 6. Use the surround display to monitor relative loudness of the individual elements rendered in a surround-sound listening environment. Check the surround sound display for performance parameters and indicators shown at right. The indicators are described under usage notes below. NOTE. The Audio Surround Sound display is courtesy of Radio-Technische Werkstaetten GmbH & Co. KG (RTW) of Cologne, Germany.
Selecting and Monitoring Audio The Center Volume indicator — Displays the sound volume of the center channel as a vertical yellow bar between the L and R channels, and connects the ends of the L, C, and R audio level indicators with straight lines. Channel-Pair Phantom Sound Indicators (PSIs) — Indicate the location of potential phantom sound sources formed by adjacent channels and are located on each side of the Surround Sound display.
Selecting and Monitoring Audio Usage Notes The following displays are examples of how the surround sound waveform appears for some typical signal types. 1. Uncorrelated signals; same level in the L, C, R, Ls, and Rs channels. 2. Sine wave test tone; same level in the L, C, R, Ls, and Rs channels. All signals are in phase, creating phantom sources between the adjacent channels. AMM768 Quick Start User Manual Artisan Technology Group - Quality Instrumentation ...
