ASSIGN

MUTE

PAN

PAN

 adjusts the amount of channel signal

sent, left versus right, to the 

SUB OUT

(and ultimately the 

MAIN OUT

 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 

GAIN

 

 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 

GAIN

 knob is set too low. Conversely, if the fader is

set way down, your 

GAIN

 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 

GAIN

 

LOW CUT

, and 

EQ

 

 settings, making it the perfect

tool for quick inspections of individual or mul-
tiple 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.
