OUTPUT SECTION You've just learned about the Channels and MAIN AUX RETURNS (A1-A4), and how the signals get in and out. In the output section, things get a bit more complicated, so put on your thinking cap. LEFT/RIGHT/CENTER MIXES This is where everything assigned via the 1-2, 3-4, 5-6, 7-8, L-R, or CENTER assignment switches gets mixed together. Just after the mix stage, the signals are sent out to the MAIN INSERTS , then they come back to their respective Faders. LEFT FADER Point Before: MAIN INSERTS . Point After: MAIN OUTPUTS . The left mix is off with this Fader fully down, the "U" marking is unity gain, and fully up provides 10dB additional gain. RIGHT FADER Point Before: MAIN INSERTS . Point After: MAIN OUTPUTS . The right mix is off with this Fader fully down, the "U" marking is unity gain, and fully up provides 10dB additional gain. To ride a stereo left/right mix, operate both Faders together, side by side, as if they were one. If a special application calls for some imbalance in levels, create that by offsetting the left and right Faders and riding that. For an even easier solution, see the following section, FADER LINK. FADER LINK Some engineers prefer to have the left and right sides of the main mix travel through separate Faders, as described above. Others prefer the accuracy and simplicity of one stereo Fader. This switch allows you to set up the LEFT and RIGHT mix Faders either way. With the FADER LINK switch up, the left mix travels through the LEFT Fader, and the right through the RIGHT Fader. With the switch down, the left mix is diverted over to the "other half" of the RIGHT Fader (actually a stereo Fader) and the LEFT Fader is out of the circuit. It'll sound the same either way, there's no performance penalty either way, and it's completely up to you. Go for it. To actually have fun with this switch, first engage it, making the RIGHT Fader control both the left and right levels while rendering the LEFT Fader useless. Now tell the producer or road manager that he's free to adjust the mix balance by tweaking the LEFT Fader to his heart's content.

OUTPUT SECTION
FADER LINK
Some engineers prefer to have the left and
right sides of the main mix travel through
separate Faders, as described above. Others
prefer the accuracy and simplicity of one
stereo Fader. This switch allows you to set up
the
LEFT
and
RIGHT
mix Faders either way.
With the
FADER LINK
switch up, the left
mix travels through the
LEFT
Fader, and the
right through the
RIGHT
Fader. With the
switch down, the left mix is diverted over to
the “other half” of the
RIGHT
Fader (actually a
stereo Fader) and the
LEFT
Fader is out of the
circuit. It’ll sound the same either way, there’s
no performance penalty either way, and it’s
completely up to you. Go for it.
To actually have fun with this switch, first
engage it, making the
RIGHT
Fader control
both the left and right levels while rendering
the
LEFT
Fader useless. Now tell the producer
or road manager that he’s free to adjust the
mix balance by tweak-
ing the
LEFT
Fader to
his heart’s content.
You’ve just learned about the Channels and
MAIN AUX
RETURNS
(
A1
–
A4
), and how the
signals get in and out. In the output section,
things get a bit more complicated, so put on
your thinking cap.
LEFT/RIGHT/CENTER MIXES
This is where everything assigned via the
1-2
,
3-4
,
5-6
,
7-8
,
L-R
,
or
CENTER
as-
signment switches gets mixed together. Just
after the mix stage, the signals are sent out to
the
MAIN INSERTS
, then they come back
to their respective Faders.
LEFT FADER
Point Before:
MAIN INSERTS
.
Point After:
MAIN OUTPUTS
.
The left mix is off with this Fader fully
down, the “
U
” marking is unity gain, and fully
up provides 10dB additional gain.
RIGHT FADER
Point Before:
MAIN INSERTS
.
Point After:
MAIN OUTPUTS
.
The right mix is off with this Fader fully
down, the “
U
” marking is unity gain, and fully
up provides 10dB additional gain.
To ride a stereo left/right mix, operate both
Faders together, side by side, as if they were
one. If a special application calls for some im-
balance in levels, create that by offsetting the
left and right Faders and riding that. For an
even easier solution, see the following section,
