AVSL 178.615 QX15AV - Manual (Page 4)

178.612, 178.615 User Manual
Take care not to incur “feedback” (howling or screeching sound through the speaker) by
keeping the microphone a sensible distance from the speaker and pointing away from the
speaker so that it doesn’t
“hear” the speaker output.
Repeat the process for the bodypack transmitter, ensuring that the level control on the
bodypack is turned up and there is a signal playing through it.
When not in use, switch the wireless microphones off.
