THE SR24•4-VLZ PRO is the latest update of our SR24•4 sound reinforcement console, incorporating our ultra-high quality XDR™ (Extended Dynamic Range) mic preamps with the best RFI rejection of any sound reinforcement mixer design on the market.
Like all Mackie mixers, the SR24•4-VLZ PRO is designed for rugged, 24-hour-a-day use. With its multiple input/ output configurations, true 4-bus architecture, 6 aux sends, and extensive routing capabilities, it can be used in a variety of live sound and recording applications. Its sturdy steel construction houses rugged, double-sided SMT-plated fiberglass circuit boards, and 60 mm faders with ultra-tight lip seals for keeping out dust and other contaminants. Impact-resistant knobs are mounted so they “ride” just above the steel chassis.
The SR24•4-VLZ PRO has 20 mono mic/line input chan- nels, with XLR mic inputs and 1/4" TRS line inputs, and 2 stereo line input channels with 1/4" TRS inputs. All mono channels have TRS insert jacks (tip = send, ring = return). Each channel strip has an input trim, 6 aux sends (2 pre- fader, 2 post-fader, and 2 switchable pre or post), 3-band EQ with sweepable midrange (4-band EQ on the stereo chan- nels), pan control, and mute, solo, and bus assign switches. A 60 mm fader provides output gain for each channel.
Twenty XDR mic preamps provide high-headroom and low-noise. They are impedance-independent, so the fre- quency response remains constant whether the mic preamp is presented with an extremely high- or low-impedance load. Additionally, each channel has its own switchable low-cut filter (18 dB/octave @ 75 Hz).
The mono channel EQs provide a range of ±15 dB at the following frequencies: 12 kHz shelving high-frequency EQ, 100 Hz to 8 kHz sweepable peaking mid-frequency EQ, and 80 Hz shelving low-frequency EQ. The stereo channels (21-24) provide ±15 dB of boost and cut at the following frequencies: 12 kHz shelving high-frequency EQ, 3 kHz peaking high-mid frequency EQ, 800 Hz peaking low-mid frequency EQ, and 80 Hz shelving low-frequency EQ.
