Model P4800 System Processor Installation Guide 2007, Shure Incorporated 27B8695 (Rev. 3) Patent No. 5,999,631 Printed in U.S.A.
ENGLISH DESCRIPTION The P4800 System Processor is a 4-input, 8-output digital audio processor. It performs all the necessary functions between the mixers and the power amplifiers in small to medium sized sound systems. Using the P4800’s drag-and-drop Graphical User Interface, processors can be placed anywhere in the signal path. The 4-by-8 matrix mixer allows any or all inputs to be routed to any or all outputs with additional controls for levels and polarity.
ENGLISH REQUIREMENTS Power S 100–240 Vac, 50/60 Hz S 60 W maximum Computer S 20 MB of hard drive space S CD ROM drive S RS–232 or RS–422 serial port S S S 9–pin serial cable for RS–232 or RS–422 VGA monitor with 640 x 480/256 color, or higher resolution Mouse or other pointing device Processor speed and memory requirements vary, depending on the version of Windows and number of background applications you are running.
ENGLISH AUDIO CONNECTIONS NOTE: The P4800 ships with a blank configuration. Audio will not pass from the inputs to the outputs until it has been configured to do so through the computer interface.
ENGLISH COMPUTER CONNECTIONS RS-232 Connect the COM port on your computer to one of the 9-pin RS-232 connectors on the P4800 device using a male-to-female serial cable, as shown in Figure 4. NOTE: Use only a standard, 9-pin, RS-232 cable wired straight-through. Other types of serial cables that use fewer pins or crossed wires will not work.
ENGLISH DIP Switch Settings for Networked Devices S Make sure the SHURE LINK/MIDI DIP switch is in the UP position (see Figure 7). S Assign each device a unique Device ID using DIP Switches 1–4 (See Table 3). Table 3. Device ID Settings IMPORTANT: Each device must have a unique Device ID number.
ENGLISH Control Input Pins Preset Control Figure 9 shows examples of how to connect different types of preset control hardware to the Control Input pins. When properly configured, the P4800 changes to the appropriate preset in response to the switch. One-to-one Configuration (Each pin represents one preset) Table 5.

ENGLISH Preset Logic Output One-to-One/Binary Configurations LEDs 5V dc Relays Binary Configuration 500Ω Resistors* BINARY LOGIC HARDWARE *Necessary for LEDs not rated for 5V. +5V WIRING LOGIC OUTPUT PINS FOR PRESET LOGIC OUTPUT Figure 12 MIDI CONTROL MIDI Connectors The MIDI port on the P4800 allows you to use a MIDI controller to change presets and perform other P4800 functions. For example, a standard MIDI message for PROGRAM CHANGE would cause a preset change in a device.
ENGLISH AMX/CRESTRON CONTROL The P4800 uses a standard 7 wire RS–232 port for control. Crestron and AMX controllers use 5 wire RS–232. In order to use a P4800 with Crestron or AMX system, you will need to build a custom cable. Refer to the following diagram for wiring instructions.
ENGLISH Certifications 4.76 mm (3/16 IN.) 431.0 mm (16–31/32 IN.) 443.7 mm (17–15/32 IN.) UL Listed and cUL Listed to UL 6500 and CSA E60065. Authorized under Verification provision of FCC Part 15 as a Class B Digital Device. This Class B digital apparatus complies with Canadian ICES–003.
