– if so, switch frequencies
“RF” and “AF” meters showing good levels but no sound
Make sure receiver is connected to mixer / amplifier
Make sure that receiver and amplifier / mixer channel volumes are turned up
Cannot Sync frequencies via IR SYNC.
Place IR Sensor closer to IR Sender
Make sure the correct channel frequency value is flashing on UHF receiver unit
Microphone output is very loud or distorted
Turn down GAIN ADJUST on beltpack transmitter
Turn down VOLUME on receiver
Reduce Gain on mixer / amplifier
Ensure that XLR output is not fed to a Line input
Microphone output is very low
Turn up GAIN ADJUST on beltpack transmitter
Turn up VOLUME on receiver
Increase Gain on mixer / amplifier
