ATPC Amplifier Terminal Panel Cabinet ATPC Components Audio power amplifiers are required to complete the audio system. The amplifier components are mounted in the Amplifier Rack (model ATPC) which may be either adjacent to the RMDP-1N or FCC enclosure or at a remote location. In systems requiring two simultaneous channels, a bank of amplifiers is required for each channel.

Channel 2 terminals provide the following: Pre-amp In - From the FCCA, Audio Distribution board, (pre-amp out) at the FCCA panel. If multiple amplifier terminal panels are used connection is from Pre-amp Out Ch #2 of the previous ATP. Pre-amp Out - to next Amplifier terminal panel (Pre-amp IN) or if it is the last Amplifier terminal panel these terminals must be terminated according to the amplifier termination chart located in the two previous sections.

ATPC Troubleshooting Amplifier Terminal Panel Trouble The amplifier terminal power is basically a panel with terminals for convenient termination of the amplifier, preamplifier and field wiring. In addition, the panel will sense a trouble condition when the power relay switches battery power to the input of the power amplifiers. The ATP power faults that will cause a TROUBLE are as follows: 1.
