RECEIVER

BELTPACK

CAUTION!

To lower the risk of potentially harmful electric shocks please do not perform any of the following procedures:

• Do not disassemble, remove screws, or otherwise in any way open the enclosure.
• Keep receiver and transmitters away from water including rain and moisture.
• Make sure there are no breaks in the A/C power cable.
• Make sure the switch is to the off position when you turn on the unit.
• Do not use this device in the rain, swimming pools or in moist damp environments.

GETTING STARTED

Step 1
Verify that all equipment including the sound system is turned off.

Step 2
Attach power supply cord to receiver.

Step 3
Make sure you have batteries in each transmitter that you plan to use.

Step 4
Plug power supply cord from receiver into the wall.

Step 5
Plug receiver into sound system. Do this by either plugging in each channel using the XLR outputs on the back of the receiver (each channel requires one XLR cable) or by connecting one 1⁄4” cable to the sound board.
Note: If you want the sound technician to be able to adjust each channel individually on your mixer, such as EQ, volume, and auxiliary send, you must use the XLR outputs, not the 1⁄4” output. Turn the channel volume controls on the receiver all the way up and  mix independently on your mixer. If you use the 1⁄4” output you must adjust (mix) your volume levels on the front of your receiver.

Step 6
Turn on receiver.

Step 7
Turn on transmitters.

Step 8
Adjust individual volume controls to desired levels.

TROUBLE SHOOTING

and the switch is put to  the “on” position.
Transmitter has no power.| Make sure the switch has been put to the “on” position. If the unit is still  not working then check the batteries in the transmitter. Each unit  requires 2 AA batteries.
The volume of each microphone is not at the the same level coming through the sound board.| Check to make sure the volume knobs on the receiver are all turned to  the same position or all the way on.
The sound is coming through on the same channel for all 4  microphones and as a result cannot be adjusted individually.| Use 4 individual XLR cables to plug into the sound board instead of the  1⁄4” cable.
Feedback| The microphone user may be too close to a speaker or stage monitor while the microphone is in use.
