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.
