AUX RETURN section
This section controls the two stereo AUX returns.
By using the L and R jacks of AUX RETURN 1/2
(page 19, A in the connector section) in pairs,
you can input stereo signals. If only the L jack of
AUX RETURN 1/2 is connected, this can be used
as a monaural AUX return. The input signal from
AUX RETURN jack 1 can also be sent to GROUP
bus 1/2 and AUX bus 1/2, and the input signal
from AUX RETURN jack 2 can be sent to
GROUP bus 3/4 and AUX bus 3/4.

1
GROUP 1/2, AUX 1/2 mix controls
These controls adjust the level at which signals
from the AUX RETURN 1 jacks are sent to
GROUP bus 1/2 and AUX bus 1/2. When a stereo
signal is input, the signals of the L and R channels
will be sent to GROUP buses 1/2 and AUX buses
1/2 respectively. When a monaural signal is input,
the same signal will be sent to GROUP buses 1
and 2, and to AUX buses 1 and 2.
2
GROUP 3/4, AUX 3/4 mix controls
These controls adjust the level at which signals
from the AUX RETURN 2 jacks are sent to
GROUP bus 3/4 and AUX bus 3/4. When a stereo
signal is input, the signals of the L and R channels
will be sent to GROUP buses 3/4 and AUX buses
3/4 respectively. When a monaural signal is input,
the same signal will be sent to GROUP buses 3
and 4, and to AUX buses 3 and 4.
3
ST (stereo) controls
These adjust the level at which the input signals
from the AUX RETURN 1/2 jacks are sent to the
ST bus. The position of the stereo control knobs
does not affect the GROUP 1–4 and AUX 1–4
mix controls (1 and 2).
4
PFL (pre-fader listen) switch
These switches send the input signal from the
AUX RETURN 1/2 jacks to the PFL/AFL bus.
When this switch is on, the input signal from the
AUX RETURN 1/2 jacks can be monitored
directly from the C-R OUT jacks or the PHONES
jack.
