LEFT/RIGHT
mix
. If you want to create a
Subgroup of certain Channels, engage one of
the numbered switches instead of the
L-R
, and
the signals from those Channels are sent to the
appropriate Subgroup Fader
. From there,
the Subgroups can be sent back to the main
LEFT/RIGHT
mix
, allowing you to use the
Subgroup Faders as a master control for those
Channels.
CENTER (assignment)
Point Before: Fader
.
Point After:
CENTER
mix
.
This switch works the same way as the other
assignment switches — engage the switch and
that Channel’s signal is sent to that mix — but
it is not a stereo destination. Since the
CENTER
assignment occurs before the
PAN
control, it
will receive the same level as the Fader output,
regardless of the
PAN
position.
Be aware:
If you’re using the
LEFT/RIGHT
MAIN OUTPUTS
but not the
CENTER OUT-
PUT
, and you want a Channel’s signal to
appear in the center of the main
LEFT/RIGHT
mix, engage the
L-R
switch and set the
PAN
control to the center. Don’t use the
CENTER
assignment switch — it won’t go anywhere,
but it will appear in the
PHONES
mix, and
that could mislead you into thinking it actually
is in the main
LEFT/RIGHT
mix.
If you want to create a
LEFT/RIGHT/CENTER
mix for your main feed, and also a
LEFT/RIGHT
mix with
CENTER
blended in for a secondary
feed, you’ll want to use the
MATRIX
section.
Use
MATRIX A
for the
LEFT
and
MATRIX B
for
the
RIGHT
secondary mix outputs. Turn
MA-
TRIX A
’s
LEFT
knob and
MATRIX B
’s
RIGHT
knob to their “
U
” markings. On
MATRIX A
and
B
, turn their
CENTER
knobs about one-third of
the way up (10:00 position).

SOLO
allows you to audition signals
through your headphones without having to
assign them to any of the
LEFT/RIGHT/CEN-
TER
mixes
or Subgroup
(
SUB 1–8
mixes)
. You can simultaneously
SOLO
as many
Channels (and other signals) as you like. The
SR40•8 features nondestructive solo: Engaging
SOLO
does not interrupt any of the other
Channels, buses, or outputs. Not only that, via
the
INPUTS PFL/AFL
and
OUTPUTS PFL/
AFL
switches in the output section, the
SOLO
system comes in two flavors:
PFL
(Pre-
Fader-Listen) and
AFL
(After-Fader-Listen,
solo-in-place).
PFL
is the key player in the all-important
Level-Setting Procedure
. It’ll send the
Channel’s actual internal levels to the
HEAD-
PHONES
, Channel Meters
and
SOLO LEFT/RIGHT/CENTER
Meters
so
you’ll know just what’s going on level-wise.
This procedure should be performed every
time a new sound source is patched into a
Channel’s
MIC
or
LINE IN
jacks.
PFL
is often the preferred mode in SR
(Sound Reinforcement, or live sound), to pre-
view Channels before they are assigned into the
mix. It won’t give you stereo placement, but will
give you signal even if the Fader is pulled down.
Remember,
PFL
taps the Channel signal be-
fore the Fader. If you have a Channel’s Fader set
way below “
U
” (unity gain), the
SOLO
mix won’t
know that and will send a unity gain signal to
the
HEADPHONES
and Meters. That may re-
sult in a startling level boost at these outputs,
depending on the position of
SOLO LEVEL
.
In
AFL
mode, the soloed Channel’s signal is
sent directly to the
HEADPHONES
and Meters
just as it would sound to the Channel’s stereo
assignment switches: post-
EQ
, post-Fader and
post-
PAN
.
AFL
works regardless of the
Channel’s assignment settings, and that makes
it handy for auditioning a Channel before you
assign it to a mix.
AFL
is the preferred mode during mixdown:
If the Channel has some midrange boost at
4.26kHz, is panned 20.3 degrees to the left, and
its Fader is at –5.38dB, that’s exactly what
you’ll hear if you solo during
AFL
-SIP mode.
It’s just as if you took the time to mute all the
other signals.
Be aware:
INPUTS SOLO
has precedence
over
OUTPUTS SOLO
— you can’t combine
these signals. For instance, if you have
SUB 1
(an output signal) in
SOLO
, then you engage
SOLO
on Channel
15
(an input signal), the
SUB 1
signal will be removed and replaced by
the Channel
15
signal.
