Setup and Operation
• The reciever should be placed in an area that is stable and least likely to
shake the unit.
• The receiver should be at least 3ˊ off the ground for optimal transmission.
• Connect the antenna, balanced cable AF line, and power supply provided.
• The antenna should extend vertically.
• Switch on the reciever.
• While the receiver is in stand-by, switch on the microphones.
• Adjust volume as necessary.
Tip:
To minimize feedback
avoid operating the
microphones in close
proximity of or in front
of speakers.
For best performance of the wireless microphone system you should make sure
that you run the cable from the receiver output (XLR or 1/4 output) into a micro-
phone input on a powered speaker or mixing board. If you run it right into a line
level input then the audio volume level output of the microphone(s) will drop sig-
nicantly. Most mixers and powered speakers have both a Microphone input and
a line level input.

Troubleshooting
Problem Soluton
No sound or faint
sound
• Verify all sound system connections or adjust
channel volume as needed.
• Verify that the receiver is connected to the mixer/
amplier.
• Turn on transmitter.
• Make sure the batteries are installed correctly.
• Charge or change battery.
• Make sure AC adapter is securely plugged into
electrical outlet.
• Make sure reciever is powered on.
Audio artifacts or
dropouts
• Change receiver and transmitter to a different
group and/or channel.
• Identify nearby sources of interference (cell
phones, Wi-Fi access points, signal processor,
etc...) and shutdown or remove source.
• Charge or change transmitter battery.
• System must be set up within recommended
range and receiver kept away from metallic sur-
faces.
• Transmitter must be used in line of sight from
receiver for optimal sound.
Distortion Reduce transmitter channel volume.
Sound level
variations when
switching to differ-
ent sources
Adjust transmitter volume as necessary.
