Troubleshooting
Problem
Solution
Feedback/distortion (a hum or
buzz on the line) occurs during all

The line may be improperly terminated. Inspect the system cable
for loose connections, shorts, and grounds. Line balance assembly
connections are critical.
Associated speaker level requires
adjustment.
Adjust the speaker volume control located on the amplifier front
panel, behind the nameplate. Refer to Figure 1. Use a small
standard screwdriver to perform these adjustments.
