prevent limit.
Incorrect gain
structure or source
input (mixing
console/preamp) is
overdriven 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.

feedback when
input level is
amplified Incorrect gain
structure 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.
