Action
Verify level controls of the source are properly structured
by using the VU meter indicator on the LCD screen. If the
VU meter bar is solid or the system indicates LIMIT, the
input or source level is too high.
Reduce the microphone levels at the mixing console or
input source. If the microphone is connected directly to the
speaker, reduce the input level on the speaker. Positioning
the microphone close to the sound source increases gain-
before-feedback. See problem 6.
Change the LOCATION to LIVE or SPEECH.
Whenever possible setup the loudspeakers so the
microphone is behind them. If using the loudspeaker in a
monitor position, aim the loudspeaker to the back of the
microphone.
Press and hold the MASTER VOL knob for 5 seconds.
