feedback frequency area Usually several red LEDs will be lit by the time you quickly cut backvolume to
kill the feedback and glance at the display. When this happens keep watching the display: the last red
LED to go off contains the exact feedback frequency (it was the first LED on, too, but you probably didn’t
see it). Adjust that slider down a couple dB and feedback problem will be reduced. If you’re real good
you’ll keep one eye on the analyzer display and quickly adjust one or two sliders when feedback occurs,
without altering master volume levels. This program monitoring feature is particularly useful for stage
monitors which are usually plagued with feedback problems.
