side, putting a dummy plug into the right input
will fool the mixer into not mono-ing the signal.

22. AUX send jacks

These are the two mono AUX outputs (see 4
& 5) or 'sends'. These send mono mixes ac-
cording to the position of the various AUX level
pots on the front panel.

23. AUX return jacks

Effects sends are typically returned through
the AUX returns, which are really just extra
input channels without the normal channel
features such as EQ. There are no laws that
say you have to use AUX return 2 to bring
back the signal from AUX send 2. An AUX re-
turn can also be used as an extra stereo input
channel if required. There is also no reason
why you shouldn't return effects through the
input channels if you need the EQ for example.

24. Tape-in jacks

These are a pair of RCA type mono jacks,
similar to those used on most tape decks and
home audio systems. The tape-in jacks of the
MM122 are electrically identical to the 1/4"
jacks of AUX return 2. When the tape-in switch
(16) is down, the RCA jacks take over from
the AUX return 2 jacks, and the AUX RTN 2
control in the main section sets the level of
the incoming signal.

25. Main outputs

The main outputs supply the final stereo mix
to a power amp, tape recorder, etc.

26. Tape-out jacks

These are alternative main outputs fitted with
RCA jacks for more widespread connection
to  cassette  decks  and  home  stereo
equipment. They output exactly the same sig-
nal as the main outputs but are unbalanced.
