Frequently Asked Questions

Q – Why was my system working fine at sound check, then suddenly it started getting
interference during the performance?
A – Using RF wireless can be quite tricky. Sources of competitive RF are everywhere, and they
can appear unpredictably. A competing RF signal that wasn't present during your sound check
probably went active during the show. This could be another member of the wireless microphone
community in the venue that was off during sound check – possibly another performer's wireless
rig was turned on during your show, and now is interfering with your system. The source could
also be a computer (CPU) positioned near the receiver or antennas that wasn't on earlier. It could
even be as pesky as a cell phone near either the transmitter or receiver, which while not being
used for a call, is sending GPS signals periodically, emitting a signal (if close enough to the
transmitter or receiver) which could be creating sporadic audible interference. To resolve, rescan
the receiver and select a new clear frequency. Then resync the transmitter to the new receiver
data.
Q – It seems that when the performer walks way out into the audience, the system starts
losing signal. Why am I not getting the range from the system I need?

Installation manual
Possible resolution
Ensure transmitter is the same
frequency band as the receiver.
Ensure that the receiver sync emitter
and transmitter sync port are not
obstructed and clear of debris. Clear
obstruction or debris if required.
Ensure clear line of sight between
receiver sync emitter and the
transmitter sync port. Aim port directly
at emitter.
Maintain recommended range of 2-12
inches between receiver sync emitter
and the transmitter sync port.
Turn on synced transmitter. If not
synced, follow sync process.
Unmute transmitter when necessary.
Use receiver up arrow button to adjust
output gain to desired level for sound
system input.
Use receiver down arrow button to
adjust output gain to desired level for
sound system input.
