Connecting the Receiver

Prior to setting up, please check that the transmitter and receiver are tuned to the same channel. Two or more transmitters operating in the same channel can not be used at the same time and area.

• Connected the provided DC power supply to the receiver power input with an appropriate AC power source. The LED display will light and the receiver is on.

• 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.
  

• Set the audio output level for MIC: -20dB
  LINE: 0dB (Default Setting)
  

• Using the Volume Controller to adjust the AF audio level to the input of the amplifier or mixer.
  Default Setting: In minimum VOLUME position.
  

Channel Setting on Receiver

Notice: Do not put two or more transmitters operating nearby when setting up the channel. Please keep transmitter at least one meter away from receiver.
Setting interference-free channel by manual operation.

• Press “Channel” button for 3 seconds till LED display is flashing.
  

• Slight press “Channel” button to change the channel forward.
  

• Press “Channel” button for 3 seconds to lock the setting.
  If you do not press “Channel” button for
  3 seconds to lock the setting, the LED will keep flashing for a while and revert to the last set channel.
