Subs (Sub 1-8 Mixes); Fader; Mute; Pan - Mackie SR40.8 Owner's Manual

Remember: INPUTS SOLO has precedence
over OUTPUTS SOLO — you can't combine
these signals.

SUBS (SUB 1-8 MIXES)

This is where everything assigned via the
1-2, 3-4, 5-6, and 7-8
switches gets mixed together. Just after the
mix stage, the signals are sent out to the SUB
INSERTS
, then they come back to their
respective Subgroup Faders.
Be aware: If the signal path of a subgroup
appears to have been mysteriously replaced by
its like-numbered AUX SEND MASTER, it's be-
cause that AUX SEND MASTER's FLIP switch
is engaged. See for more details.

FADER

Point Before: SUB INSERTS
Point After: MUTE
.
A SUB mix is off with this Fader fully down,
the "U" marking is unity gain, and fully up
provides 10dB additional gain.

MUTE

Point Before: Fader
Point After: SUB OUTPUTS
CENTER (assignment)
inputs.
Muting a SUB removes the signal from
these output paths: SUB OUTPUTS, SUB
CENTER/L-R (ASSIGN), AFL SOLO, and the
respectively-numbered MATRIX input. The
INSERT, PFL SOLO, and PFL Meter paths are
not affected.
Pressing the switch toggles the electronic
mute relay in the signal path's circuitry. If the
signal is muted, pressing the switch un-mutes
it, and vice versa. An LED adjacent to the
switch glows when it is muted.
With ULTRA MUTE
™
different Mute Groups can be configured, en-
abling you to mute several signal paths at
once. Not only that, but you can automate the
muting of all the signal paths via an external
MIDI sequencer or via the RS-232 DATA
port connected to a computer. We'll discuss all
this in detail later on

PAN
Point Before: MUTE
Point After: L-R (ASSIGN)
PAN does not affect a subgroup's dedicated
SUB OUTPUT. PAN adjusts the amount of sig-
nal sent to the LEFT versus the RIGHT mixes via
the L-R (ASSIGN) switch and the SOLO bal-
ance (in AFL mode). With the PAN knob hard
left, the signal feeds the LEFT mix
left AFL SOLO (assuming their assignment
switches are engaged). With the knob hard
right, the signal feeds the RIGHT mix
the right AFL SOLO. With the PAN knob set
somewhere in between left and right, the signal
is divided between the LEFT and RIGHT buses.

L-R (ASSIGN)

Point Before: PAN
.
Point After: LEFT/RIGHT mixes
If you're doing a conventional stereo mix
and using the Subgroups as master controls
for groups of Channels before they enter the
LEFT/RIGHT mix (by assigning these Chan-
nels to the Subgroup only
the Subgroup's L-R switch, and the signal will
be sent to the LEFT/RIGHT mix. With the
PAN knob set at the center detent, the left
and right sides receive equal signal levels. To
feed only one side or the other, turn the PAN
knob accordingly.

CENTER (ASSIGN)

Point Before: MUTE
Point After: CENTER mix
This switch works the same way as the
Subgroup's L-R assignment switch — engage the
switch and that signal is sent to the CENTER
mix — but it is not a stereo signal. Since the
CENTER assignment occurs before the PAN
control , it receives the same level as the
Fader output regardless of the PAN position.
Be aware: If you're using the LEFT and
RIGHT MAIN OUTPUTS but not the CENTER
OUTPUT, and you want a subgroup's signal to
appear in the center of the main LEFT/RIGHT
mix, engage the L-R switch
PAN control
to the center. Don't use the
CENTER ASSIGN switch — It won't go any-
where, but it will appear in the PHONES mix,
and that could mislead you into thinking it
actually is in the LEFT/RIGHT mix.
If you want to create a LEFT/RIGHT/
CENTER mix for your main feed, and also a
