Connecting the receiver
Prior to setting up, please check that the transmitter and receiver are tuned to the same frequency or channel. Two or more transmitters operating in the same frequency can not be used at the same time and area.
¾ Connected the provided DC power supply to the receiver power input with an appropriate AC power source. The LCD display will light and the receiver is on.
2
¾ Using a standard audio cable with 3-pin XLR connectors or 6.3mm phone plugs to connect the mixer or amplifier.
Never use the balanced and unbalanced audio outputs at the same time! This may cause signal loss or increased noise.

Use squelch to avoid reproducing noise when the receiver does not receive enough signal from the transmitter.
Turn clockwise to increase squelch and reduce noise. When turning the squelch knob clockwise, it begins to eliminate background noise.
When the squelch is all the way to the left, the squelch is off and the ambient RF noise will be easily to receive.
