2. OUTPUT SECTION CONNECTORS
1. 4 STEREO INPUT JACKS
These are unbalanced 1/4 ″ phone jacks which input a stereo source with a nominal input and impedance of
+4dB -10dB/600 Ω .
If a plug is inserted only in L/MONO, the same signal will be sent to both the L and R buses.
2. 6 AUX RETURN JACKS
These are unbalanced 1/4 ″ phone jacks with a nominal level and impedance of +4dB/10k Ω .
These jacks are usually used to receive the audio returned from an effect unit such as reverb or delay, but they
can also be used as supplementary inputs.
If a plug is insterted only in L/MONO, the same signal will be sent to both the L and R buses.
These allow you to return signal from outboard devices, either in stereo pairs or mono phonically ( many popular
effects processors provide a single mono input but have a pair of stereo outputs).
In practice, you'll probably want to use the Auxiliary returns to bring in signal from connected effects processors.
If the effects processors have stereo output, they should be connected to both the left and right Auxiliary return
inputs so that their stereo integrity is retained . If they have mono outputs, you can route them to either the left or
right inputs and then use the Auxiliary return Balance control to adjust the relative level of each paired signal.
3. 8 AUX SEND JACKS
These are unbalanced 1/4 ″ phone jacks with a nominal output and impedance of +4dB/600 Ω .
The AUX SEND output signal is the sum of all of the input channel AUX SENDS.
