AUX 1 in POST-mode and AUX 2 are
post- LOW CUT, post-EQ and post-FADER. That
is, the sends obey the settings of these controls.
AUX 1 in PRE mode follows the EQ and LOW
CUT settings only. PAN and FADER have no ef-
fect on the
PRE send (see diagram below).
All AUX send levels range from off through
unity (with their channel gain controls at the
center detent position) on up to 15dB of extra
gain (when turned fully clockwise). Chances
are you’ll never need this extra gain, but it’s
nice to know it’s there if you do.
Channel 7–14 AUX pots control the mono
sum of the channel’s stereo signals for each
AUX send. For instance, Channel 7 (left) and
8 (right) mix together to feed that channel’s
AUX send knobs.
We recommend going into a stereo reverb in
mono and returning in stereo. We have found
that most “stereo” reverbs’ second input just ties
up an extra
AUX send and adds nothing to the
sound. There are exceptions, so feel free to try it
both ways. If your effects device is true stereo
all the way through, use
AUX 1 to feed its LEFT
input and AUX 2 to feed the RIGHT input.

Moderation during EQ
With EQ, you can also screw things up roy-
ally. We’ve designed a lot of boost and cut into
each equalizer circuit, because we know
everyone will occasionally need that. But if you
max the
EQs on every channel, you’ll get mix
mush. Equalize subtly and use the left sides of
the knobs (cut), as well as the right (boost).
Very few gold-record-album engineers ever use
more than about 3dB of
EQ. If you need more
than that, there’s usually a better way to get it,
such as placing a mic differently (or using a
different kind of mic entirely).
AUX SEND
These tap a portion of each channel signal
out to another source for parallel effects pro-
cessing or stage monitoring.
AUX send levels
are controlled by the channel’s AUX 1 and AUX
2 knobs and by the AUX 1 MASTER .
These are more than just effects and moni-
tor sends. They can be used to generate
separate mixes for recording or “mix-minuses”
for broadcast. By using
AUX 1 in the PRE
mode , these mix levels can be obtained in-
dependently of the channel’s
GAIN control.
