Overview
The ARP-7805 Remote Audio Gain Panel has been designed for remote gain control of the Ross RSA-
7806 Remote Gain Stereo Amplifier. The single rack unit control panel module provides twelve 10K
potentiometer controls which are connected to the rack frame via three 14 pin terminal blocks at the
rear of the panel. The three rear terminal blocks provide three connections for each of the twelve
controls: +5V, the control wiper, and a ground.
Inter-connection between the panel and the rack frame is made using a standard shielded audio twisted
pair cable. Single or multiple channel control is possible by wiring each channel’s remote control pins
independently or connecting multiple channel controls together and wiring them to a single control
panel potentiometer.
The audio signal inputs and remaining outputs are connected according to the standard stereo wiring
template outlined on the rear of the rack frame.
Installation
Use the following steps to install the ARP-7805 Remote Audio Gain Panel:
1. Install the RSA-7806 distribution amplifiers in an Audio distribution frame.
2. Determine the remote panel location and the number of controls you will require for
the installation.
3. Run a shielded twisted pair cable for each control in which you wish to use, from the
panel to the frame location. Be sure and identify each cable to allow for proper
allocation of each channel control.
4. Once the cables have been routed, at the control panel, wire the three conductors of
each cable to the desired control. Connections are as follows:
