Channels can be assigned to buses 1-2, 3-4, and
Main Mix L/R, and the 4 subs can be assigned to
Left
and Right Main Mix. Furthermore, each bus is
“double-bused,”
providing eight outputs that can be
connected to an 8-track recorder without repatching.
Each sub out (1-4) and main out (L/R) has a TRS insert
jack. Furthermore, Mackie’s unique “AIR” EQ circuit is
included on each of the four subgroups. It provides a
gentle nudge to the extreme high-end, without affect-
ing lower treble octaves.
Outputs include XLR and 1/4" TRS line outputs for
the left and right mains, 1/4" TRS line outputs for
subs 1-4, and an XLR mono main output. The mono
main out has its own level control, so a mono mix can
be sent to another zone and adjusted accordingly.
The Phones/Control Room switch and level control
are connected to two stereo headphone outputs and
the left and right Control Room output, allowing the
stereo Tape Return, Left/Right Main Mix, and Solo to
be monitored.
A stereo playback device can be monitored via the
Tape Return Inputs. Tape Return to Phones/C-R routes
the tape playback signal into the monitor system and
meters, and the Tape Return knob adjusts the level of
playback, which can be monitored via headphones.
Tape Return signals can also be assigned directly to
the Main Mix. The SR24•4-VLZ PRO also has RCA-style
Tape Outs for output to conventional stereo recording
devices.
Each of the six aux sends has its own individual
master send control, driving 1/4" TRS output jacks.
Six stereo aux returns are provided, with 1/4" TRS
input jacks. Two aux returns can be folded back into
Aux Sends 1 and 2 via their own volume controls to
add effects in stage monitors.
An XLR input is provided for a talkback mic, which
can be assigned to the Main Mix or to Aux 1-2. The
talkback mic has a level control in the talkback section.
