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
NOTE
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.
