8 RETURN 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.
9 REC 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.
