SECTION 3: OFFICIAL GUIDED TOUR —
PANEL LAYOUT & FUNCTION
Those of you with a lot of sound mixing
experience can see that the Mackie SR24•4
(and 32•4, obviously) has a pretty straightfor-
ward layout, and you may not need to take the
detailed Guided Tour which follows. However,
we've built a few tricks into the SR24•4, and
you might want to take particular notice of
the solo mode switch, the various EQ curves
and some of the special switching in the
Monitor/Output Section. Check for the VERY
IMPORTANT icons.
Everyone else, the tour leaves at the next para-
graph in about 5 seconds. Shirts and shoes are
recommended but not mandatory; cameras and
recorders are allowed. Please, please do not feed
the Chihuahua, no matter how much it begs.

FRONT PANEL

Most of the Mackie SR24•4 front panel
consists of the 22 channel strips for the mixer
inputs (30 on the 32•4). You'll notice that
Channel Strips 1–20 (or 1–28) are identical
(MOTTO: Learn one and you learn them
all) and that the strips numbered 21–22 and
23–24 (or 29–30 and 31–32) are almost the
same, but in stereo (MOTTO: Learn one and
you learn both). You can already see this
promises to be painless.
To the right of the channel strips is an area
which we can call the Monitor/Output Section
and be right most of the time. This is where
you set and meter the overall volume level,
make adjustments to solo, auxiliary and
headphone levels and accomplish other
miscellaneous essential tasks.
