HAVING TROUBLE WITH YOUR SOUND SYSTEM?
CONDITION
POSSIBLE CAUSE
No Sound
• power supply turned off on the transmitter and/or receiver
• transmitter and receiver are set to different frequencies
• transmitter output is not connected to mixer or amplifier input
• receiver is too far from transmitter
• metal object near transmitter or obstructions between transmitter &
receiver
Sound Interference
• adjust the antenna location
• when using 2 or more transmitters use different frequency setting for each
• interference from other wireless microphone, TV, radio, etc.
Distortion
• transmitter volume level too high or to low
• interference from other wireless microphone, TV, radio, etc.
