Setup and Operation

Most mixers and powered speakers have both a Microphone input and a line level input. For best performance of the wireless microphone system you should make sure that you run the cable from one of the receiver outputs (XLR, 1/4" output) into the line input of the powered speaker or mixing board.

• The receiver should be placed in an area that is stable and least likely to shake the unit.
• The receiver should be at least 3' 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 receiver.
• 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.
