Adjusting the Audio Gain Level

5.1  Adjusting the Audio Gain Level

The Installer can use a multi-position rotary switch to adjust the gain of the audio output signal to 
compensate for audio line losses. After you make the correct adjustment, the audio amplifier pro-
duces its maximum rated output power.

5.1.1  Procedure to Adjust the Audio Gain Level

After you complete the installation of all 
amplifiers and associated circuitry, adjust 
the low-level audio input to the amplifier 
set for normal standby. To adjust the 
audio gain level, do the following:

Figure 5.1.1.1 shows the Audio Gain switch.

1. Use a small slotted screwdriver to 

position the rotary switch until the 
NORMAL LEVEL LED is lit and 
the INCORRECT LEVEL LED is 
off.

2. The audio gain is properly adjusted.

Figure 5.1.1.1    Audio Gain Level Diagram

NOTE:  R-470 Resistor Installation Requirement:

You can install an R-470 resistor assembly across P3, (pins 4 and 5) of the last directly connected 
device on the low-level audio riser. This installation calibrates the audio amplifier. Failure to do so 
will cause a calibration difficulty.
