2. Audio Output Connection:
(A) 1/4” Unbalanced Output: Connect from the unbalanced
output jack (7) of the receiver the input jack of the amplifier,
as shown in Fig. 3.
This outputs the sound from both microphones
to mixer or
a 1/4” cable
together.
(B) XLR Balanced Output: Connect an XLR cable from the balanced
output jack (8) of the receiver to the input jack of the mixer or amplifier,
as shown in Fig.3. There are two individual outputs corresponding to
the two microphones.

3. Extend antennas A & B. Make them perpendicular with the
machine.
4. Push the power switch to turn on the unit.
5. Adjust the volume using the control knobs on the receiver.
Receiver Location
• The receiver should be placed more than 3 ft. above the floor and
3 ft. away from the wall.
• Antennas should be fully extended for best reception.

5. Troubleshooting
1. Unit does not turn on.
• Make sure the power cable is connected properly.
• Check the fuse.
• Check the voltage selector
2. AF display moves, but there is no sound output.
• Check volume level.
• Check audio cable.
• Check the settings on your amplifier
3. The effective receiving distance decreases.
• Change batteries.
• Check for any devices that may be causing interference.
4. Sound Quality Deteriorates
• Change Batteries.
• Check for any devices that may be causing interference.
• Do not use two machines with the same frequency at the
same time.
Caution:
Do not open the unit. There are no user serviceable parts
inside. Refer service to a qualified technician.
