ABOUT THIS MANUAL The stuff you MUST read: Further information: This icon marks information that is critically important or unique to your mixer. For your own good, read and remember them. First, you must read and follow all the safety instructions on page 2. Before you get to work, please read the “Quick Start” section on page 6. It’s a list of steps that will familiarize you with the mixer and help you set up a basic performance.

Set these controls fully down (for rotary controls, “down” refers to the Control Fully Down fully counter-clockwise position; for faders, it refers to all the way down): 1. On the rear panel, turn the POWER switch and the PHANTOM off, and the OUTPUT LEVEL fully down. Switch Up 2.

MAKE THE CONNECTIONS: 1. Make sure your amplifiers are turned off before making any connections. 2. Connect speakers to your amplifier’s outputs (unless, of course, you have powered speakers, such as the Mackie SRM 450 active monitors). 3. Plug all the sound system components into suitable AC outlets; properly grounded and capable of delivering adequate current. Use power strips to minimize ground loops. 4.

3. INSERT EFFECTS: SERIAL OR PARALLEL? With nothing plugged into this jack, the channel’s signal goes straight through the mic/ line preamp to the channel strip. With an external effects device plugged into this jack, the channel’s signal leaves the mixer, goes through the effects device and back into the channel strip. Use these jacks to send the channel signal through a compressor, graphic equalizer or similar device.

CHANNEL STRIP FEATURES The channel strip is where you dress up each channel’s audio: setting the gain, adding EQ, riding the fader, tapping signal off to stage monitors and effects devices. After a signal leaves the channel strip it goes through a mix stage and on to the master section (page 22). The 24•4-VLZ PRO has 20 mono channels and two stereo channels. The 32•4-VLZ PRO has 28 mono channels and two stereo channels. All of the mono channels are identical, and all of the stereo channels are identical.

Mono channels 35. THIS OL’ LED 39. SOLO This LED represents a bad thing: If a channel’s OL LED lights up, its signal is too hot, and subsequent circuitry may overload (clip). To correct this, perform the SET THE LEVELS procedure on page 8. Engaging this switch isolates the associated channel’s signal and sends it to the control room, phones and meters. See RUDE SOLO LIGHT (61) and MODE (63) for more information. 36. -20 LED Note: A muted channel can still be soloed (set MODE (63) to PFL).
PAGE 22
MASTER SECTION FEATURES In the master section, signals leaving the channel strips are mixed, manipulated and sent to the outputs in the patchbay. Additionally, there are four more stereo inputs here, used to add effects to the main mix or other destinations.

STEREO AUX RETURNS: (48 to 52) 53. TAPE RETURN 48. STEREO AUX RETURNS Having entered through the TAPE IN (6) jacks, tape returns are controlled by this knob, and then sent to TAPE RETURN TO PHONES/ C-R (69) and TAPE RETURN TO MAIN MIX (71). Having entered through the STEREO AUX RETURNS (9) jacks, effects returns are controlled by these knobs, and typically continue on to the MAIN MIX FADER (72).

SUBGROUPS: (56 through 60) LAMP 56. AIR U U U AIR is a high frequency peaking EQ centered at 16kHz. Turned fully up, these controls provide 10dB of boost and fully down effectively bypasses the circuit. Use AIR to provide a crystalline effect to subgroups, helping them stand out in the overall mix.
PAGE 25
60. SUBGROUP FADERS These faders provide 10dB of gain fully up, unity gain at the “U” label and are effectively muted fully down. Each fader is the master level control for a subgroup’s signal, affecting both the SUB OUTS (8) and the main mix, via L/R ASSIGN (59). lar for studio recording applications; providing the actual outputs of individual or multiple channels. 64.
