(Radio Frequency) signal levels.

3. One receiver has two built-in units (Receiver A and Receiver B).

4. Easy to select channels with pre-set frequencies.

5. Each microphone has 32 channels. There are a total of 64 frequencies in

two microphones.

6. Easy and convenient mounting for portable rack.

7. Adjustable antennas for different angles to receive better signals.

RISK OF ELECTRIC SHOCK

DO NOT OPEN

Taking apart or modifying the

receiver may lead to electric shock,

fire, or damage to the receiver and

HOW TO CONNECT AUDIO OUT

There are three different connectors as shown in the following diagram:

• Connector 1 is a channel B XLR-balanced audio out

• Connector 2 is a mixed audio output (Channel A and Channel B)

• Connector 3 is a channel A XLR-balanced audio out

Connector 1 (Channel B) is a balanced XLR audio signal. If you connect B to the

mixer or amplifier, then you can control the microphone effect on MIC. B only.

Connector 2 is an unbalanced 1/4 audio signal. If you connect to Connect 2

(1/4), both MIC. A and MIC. B will mix together to produce the same signal. If

you want to produce different effects on MIC. A and MIC. B, you need to

connect to XLR (Connector 1), which is equivalent to channel B, and XLR

(Connector 3), which is equivalent to channel A. You can also adjust different

echo or mic. tone effects on each microphone (i.e. MIC. A and MIC. B).

Connector 3 (Channel A) is a balanced XLR audio signal. If you connect A to the

mixer or amplifier, then you can control the microphone effect on MIC. A only.
