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

NOTE

control in the Master Control section.

APOWER Switch

Use this switch to set mixer power to ON or STANDBY.

Note that trace current continues to flow while the switch is in the STANDBY position. If you do not plan to use the mixer again for a long while, be sure to unplug the adaptor from the wall outlet.

BAC ADAPTOR IN Connector

Connects to the included PA-20 power adaptor (see page 5).

Use only the PA-20 adaptor included with this mixer. Use of a different adaptor may result in fire or electric shock.
