L/R ASSIGN
There is a L/R ASSIGN switch [2] above
each bus fader. The submix bus audio signal
is always routed to the SUB OUT jacks on the
rear panel. Additionally, the L/R ASSIGN
switch [2] on the SUB strip can assign the
submix audio to the main Left/Right Buses.
This allows you to submix several channel
strips to one fader for easier control, and then
re-assign that bus into your final mix.
PAN
When the L/R ASSIGN switch is pressed,
the PAN control [3] allows you to position
the submix signal at any point in the L/R ste-
reo field. As with all Mackie pan pots, there is
a detent at the top of the control for center
positioning.
SOLO
The SOLO button [5] solos the submix in
the same manner as the channel SOLO

switch. The SUB SOLO LED [6] (near the
SOLO level control) flashes when this
SOLO is used.
As in the channel strips, the SUB SOLO
mode can be switched from PFL to Solo-
in-Place (SIP) via the solo MODE
switch. There's a catch, though: in SIP
mode, submixes cannot be soloed until
you depress the L/R ASSIGN switch.

neering staff to decide what to fill it with.
Entries ranged from a combination ash tray/nut
dish to a tiny crystal pyramid (to keep razor
blades sharp). After rehabilitating his engineer-

a special form of EQ set
into the submix masters, a
smooth, broad hill of shiny
hyper-treble centered at
16kHz, with gossamer
skirts extending as low as
12kHz and wafting as high
as 20kHz. When AIR is set
at 0, it is effectively out of
the signal path and the
submix bus has a flat
response. But when you
need a little more "air" in
your sound, just a hint of
high treble to add that at-

your vocalists or that

your guitar, give the AIR
knob a twist. We think
you'll like it.
