Action
Reduce the microphone signal by reducing the
INPUT level. Positioning the microphone close
to the sound source increases gain before
feedback.
Whenever possible, setup the loudspeakers so
the microphone is behind them. If using a
separate loudspeaker in a monitor position, aim
the loudspeaker to the back of the microphone.
Ensure Bluetooth® is enabled on the
loudspeaker.
Use shielded CAT5 (or better) cables that are
not longer than as specified in the datasheet.
Only a direct connection between no more than
two EVOLVE50M systems is allowed to work
correctly.
