MACKIE STEREO INPUTS AND RETURNS:
Mono, Stereo, Whatever
The SR24•4 stereo line inputs and stereo
AUX returns are a fine example of the Mackie
philosophy (which we just made up) of Maxi-
mum Flexibility with Minimum Headache.
The inputs and returns will automatically be
mono or stereo, depending upon how you use
the jacks. Here's how it works:
A mono signal should be patched into the
input or return jack labeled Left (MONO).
The signal will be routed to both the left and
right sides of the return circuit, and will show
up in the center of the stereo pair of buses it's
assigned to, or can be "panned" with the
Balance control.
A stereo signal, having two plugs, should be
patched into the Left (MONO) and the RIGHT
input or return jacks. A jack switch in the
RIGHT jack will disable the mono function, and
the signals will show up in stereo.
A mono signal connected to the RIGHT jack
will show up in the right bus only. You probably
will only want to use this sophisticated effect for
special occasions (weddings, bar mitzvahs, Rush
Limbaugh's birthday party, etc.)
MULTS AND "Y"s
A mult or "Y" connector allows you to
route one output to two or more inputs by
simply providing parallel wiring connections.
Channel Insert jack
You can make "Y"s and mults for the outputs
of both unbalanced and balanced circuits.
Channel Insert jack
use a mixer, not a mult or a "Y."
Example: Let's say you're engineering a
show. You have two monitor mixes but only
one reverb device. You want to send some of
this reverb to each monitor mix, but the
SR24•4 doesn't seem to allow this. It's
Y-CORD time.
Channel Insert jack
From the reverb outputs, plug the left
reverb into AUX RETURN 1 left and, via the
Y-cord, AUX RETURN 2 left. Do the same for
the right.
Now, AUX RETURN 1 and 2 will act indepen-
dently, even though they receive the same signal!

inputs. If you need to
combine several outputs
into one input, you must
