8RETURN L (MONO), R Jacks

These are unbalanced phone-type line input jacks. The signal received by these jacks is sent to the Stereo bus and the AUX1 and AUX2 buses. These jacks are typically used to receive a return signal from an external effector (reverb, delay, etc.).

These jacks can also be used as an auxiliary stereo

NOTE input. If you connect to the L(MONO) jack only, the mixer will recognize the signal as monaural and will propagate the identical signal on both L and R jacks.

9REC OUT (L, R) Jacks

By connecting these jacks to an external DAT recorder or cas- sette recorder, you can record the same signal that is being out- put from the ST OUT jacks.

The mixer’s ST Master Fader has no affect on the

NOTE signal output from these jacks. Be sure to make appropriate level adjustments at the recording device side.

Front & Rear Panels

02TR IN Jacks

These RCA pin jacks input a stereo sound source. Use these jacks when you want to connect a CD or DAT directly to the mixer for monitoring.

You can adjust the signal level using the 2TR IN

control in the Master Control section.

APOWER Switch
