SOLO

PAN
PAN
 adjusts the amount of channel signal
sent, left versus right, to the 
SUB OUT
s 
(and ultimately the 
MAIN OUT
s   via the
SUB ASSIGN
   switches). On mono chan-
nels, the knob places the signal somewhere
between hard left and hard right. On stereo
channels, it works like the balance control on
your home stereo, by attenuating one side or
the other.
With the 
PAN
 knob hard left, the signal will
feed 
SUB 1
 and 
SUB 3
 (assuming the channel’s
ASSIGN
   switches are engaged).
With the 
PAN
 knob hard right, the signal
will feed 
SUB 2
 and 
SUB 4
 (assuming the
channel’s 
ASSIGN
   switches are engaged).
With the 
PAN
 knob set somewhere in be-
tween, the signal will be shared across both
sides of the mix.
MUTE
When you engage a channel’s mute switch,
its signal disappears from these outputs: 
MAIN
OUT
  , 
MAIN INSERT
  , 
SUB OUT 1-4
  ,
AUX SEND 1 & 2
  , 
EFX SEND 1 & 2
(including the send to the 
EMAC EFFECTS
PROCESSOR
  ). The only thing it doesn’t
mute is the channel’s 
SOLO PFL
   switch, so
you can audition channels, via headphones,
without sending them to the main mix.
ASSIGN
Used in conjunction with the 
PAN
   knob,
ASSIGN
 determines the final destination of a
channel’s signal. Engaging 
ASSIGN 1-2
, for in-
stance, sends that channel’s signal to the 
SUB
1
 and 
2
 Faders   and, via their 
SUB ASSIGN
switches, the 
MAIN MIX
 Fader  .
Typically, 
ASSIGN 1-2
 will be engaged on all
channels destined for the main mix. By config-
uring 
SUB 1
 and 
2
 to feed the main mix, the
channel 
ASSIGN 1-2
 switches become the
equivalent of being “Main Mix” switches.
Some channels can use 
ASSIGN 3-4
 in-
stead; creating a submix for a set of channels
(all the drum channels, for instance). Then, by
configuring 
SUB 3
 and 
4
 to also feed the main
mix, you can “ride” the 
SUB 3
 and 
4
 Faders 
independently of the rest of the mix.
SUB
 Faders  , 
SUB ASSIGN
  , and
MAIN MIX
 Fader   will explain this further.
FADER
Although the most self-explanatory item on
a mixer, we’ll explain it anyway: The fader is
the master level control for the channel’s sig-
nal. Subtle adjustment of the channels’ fader
positions is the key to a finely-tuned mix.
Typically (providing the 
TRIM
   knob is set
correctly) the fader position will be positioned
somewhere between 0 dB (“
U
”) and –30 dB.
If you have a fader set all the way up, adding
10 dB of gain, that’s usually a sign that your 
TRIM
 knob is set too low. Conversely, if the fader is
set way down, your 
TRIM
 may be set too high.
“U” LIKE UNITY GAIN
Mackie mixers have a “
U
”
symbol on almost every level
control. This “
U
” stands for
“unity gain,” meaning no
change in signal level. Once
you have adjusted the input signal to line-level,
you can set every control at “
U
” and your sig-
nals will travel through the mixer at optimal
levels. What’s more, all the labels on our level
controls are measured in decibels (dB), so
you’ll know what you’re doing level-wise if you
choose to change a control’s settings.
SOLO PFL
Engaging a channel’s 
SOLO
 switch causes
this dramatic turn of events: The 
PHONES
and Meters  , which ordinarily receive the
main mix signals, instead receive the 
SOLO
PFL
 signal. PFL, being a mono signal, is sent to
both sides of the 
PHONES
 outputs and to the
LEFT
 meter. Additionally, the 
RUDE SOLO
LED flashes obnoxiously to remind you that
“you’re in solo.”
The 
SOLO PFL
 signal is tapped before the
channel’s 
MUTE
   and Fader   controls. It
does, however, follow 
TRIM
  , 
LOW CUT
  ,
and 
EQ
   settings, making it the perfect tool
for quick inspections of individual or multiple
channels. The channel’s 
PAN
  , 
MUTE
and Fader   settings have no effect on the
SOLO
 signal. See 
RUDE SOLO
   for more
information.
WARNING: Pre-fader
SOLO
 taps the channel
signal before the fader 
.
If you have a channel’s
fader set well below “
U
”
(unity gain), 
SOLO
 won’t know that and will
send a unity gain signal to the 
PHONES
output. That may result in a startling level
boost in your headphones.
