will distort or "clip" the electronics of the MM-1. Oc ­
casional flashing of this light is OK, but if it's on con ­
stantly you should turn down the TRIM or the volume
control on your instrument. Conversely, if only the green
LE D is on wh ile you're playing, and you have to boost the
CHANNEL FADER to get enough signal to the output,
operation will be noisier than if you increased the
TRIM to its proper level. Signal to the LEVEL LEDs is
affected by the input device level, the TRIM, and the
EQ, but not by the CHANNEL FADER or MUTE. See
p. 10, "Setting Input Levels."
MASTER SECTION
10. EFFECT SEND MASTERS 1-4: These are the
master volume controls for the four effect send mixes.
They get their signal from the EFF
1/2 and EFF 3/4
controls in the channels to their left. The signal then
goes to the EFFECT SEND output jacks on the back
panel. Adjust the EFF SEND MASTERS until you have
the correct level feeding your external effects device. See
p. 10, "Setting Levels: To Effect Devices".
11. STEREO EFFECT RETURNS 1-4: These control
how much signal from the four EFFECT RETURN
JACKS is mixed onto the L!R stereo buss and then the
L/R MASTER FADER. The EFFECT RETURNS con­
trol how much signal goes I N to the MM-1, coming back
from the effect device, as compared to the EFFECT
SENDS, which control how much goes OUT of the
MM-' to an external effect device (such as a reverb un it).
The unity gain point of the effect return controls is the
"12 o'clock" position.
A special feature of the MM-1's EFFECT RETURN
system is that it is capable of receiving 4 stereo returns,
which on conventional designs would requ ire 8 effects
returns. Each EFFECT RETURN level control in fact
sets the level of 2 signals, left and right, if you are using
the special stereo plugs that can take advantage of it. See
p. 5, "Quarter-I nch Stereo (TRS) to 2 Mono ill nsert"
or "Stereo Splitter" cables".
On the other hand, if you use mono effect retu rns, there
is a way that you can "pan" them between the left and
right sides of the mix. If a signal (for example, the out­
put of a reverb) is plugged into return #1, but there is
nothing plugged into return
#2,
the reverb signal will go
to both EFFECT RETURN 1 and EFFECT RETURN 2
controls. In this "mono" mode, EFFECT RETURN 1
controls how loud the reverb will be on the left side, and
EFFECT RETURN 2 how loud it will be on the right
side. You can vary the two controls to send signal any­
where between the two groups, similar to using a pan
pot. EFFECT RETURNS 3 and 4 work the same way.
For more information on effect returns, see p. 7,
"Choosing Effect Returns", p.
8,
"Mono Effect Re ­
turn", and pp. 11-12, "Setting Levels: From Effect
Devices".
12. L!R MASTER FADERS: These faders adjustthe out ­
put levels of the mixer. They get their signal from the
left and right mix busses, which are fed by the channel
PAN controls. They send signals to the four L!R OUT ­
PUT jacks on the back panel, to the PHONES LEVEL

control, and to the meters. These controls should be set
to the proper level for the ampl ifier or recorder they are
connected to. See p. 10, "Setting Output Levels".
13. L/R MASTER MUTES: These work the same way
as the MUTE/SO La keys if] the channels, except they
have no effect in SOLO mode, They turn the signal on
or off to the stereo output headphone jacks. The
most common use is to siI8';1ce your rig temporarily, for
example du breaks.
