The VLZ3 is an improvement on the favored design with enhanced XDR2 microphone preamplifiers, an ultra quiet mix bus with improved headroom and a new look.The1604-VLZ3 provides the quality and features that target most recording, P.A. and live applications. The Popular 1604-VLZ3 features sixteen line inputs, switchable between balanced and unbalanced signal. Sixteen insert points are standard and provide plenty of routing options to external signal processors. The 1604-VLZ3 features Extended Dynamic Range (XDR2) mic preamps that result in pristine, transparent audio signal at an impressive 130dB of Dynamic Range. XDR2 mic preamps are optimized to meet the demands of 24-bit, 192kHz recording.The rugged design and steel chassis virtually eliminates noise caused from poorly shielded cable and ground loops. The 3-band EQ section features a sweepable mid range and four AUX sends provide options for routing signal to effect processors. Four dedicated buses and eight direct outputs provide plenty of routable outputs for sending signal to multitrack recorders, monitor feeds etc.Key FeaturesImproved XDR2 Microphone Preamplifiers
Featuring four improved XDR2 microphone preamps provide an impressive 130dB of Dynamic range. The microphone preamps deliver a wider frequency range than the older XDR mic preamps.Improved Mix Bus
All VLZ3 series mixers have more headroom and less distortion thanks to an improved mix bus. Negative Summing results in a quiet output signal with improved gainDurable 60mm Fader Control
60mm tapered faders control Channel, "Sub Group 1-4" and "Main Mix" level. Rugged Construction
All steel construction virtually eliminates noise caused by bad grounding. Because the chassis is steel, connections are automatically grounded on contact.Flexible Routing Options
The 1604-VLZ3 PRO provides Inserts on all channels and "Main Mix" out. There are 8 direct outputs on channels 1-8 and 4-direct Sub-Groups for routing input channels to multitrack recorders, monitor feeds etc.Switchable Soloing

The mixer is equipped with dual 32-bit RMFX+ effect processors, each with 24 effects including tap delay. It also includes compression on dedicated channels and subgroups that allow for simple, sweet dynamic control.Additionally, both of the FX processors feature a tap delay and the delays may easily be synchronized with the song at the tap of a finger. The processed signal may be sent directly to the mains and monitors from the effects section or re-routed to the 2 stereo channels to bring them through the EQ and AUX section, utilizing the 60mm fader to draw them into the mix.The 24-channel, 4-bus FX mixer has 8 single-knob compressors to stop the dynamic signals from poking out of the mix. There are 4 compressors are located on the last 4 microphone inputs so that critical signals (such as vocals, snare drum, guitar or keyboards) may be addressed. In addition, there are single-knob compressors on each of the 4 subgroups so that grouped signals (such as a drum set or a choir of vocalists) may be blended together for paramount smoothness.This mixer also features a 4 x 2 USB recording and playback function. This means that up to 4 signals may be recorded simultaneously and a stereo mix returned to the mixer for playback. Its built-like-a-tank construction delivers years of reliable use under strenuous conditions. The VLZ4 4-Bus Series offers a compact FX mixer solution in a design that’s flexible, rugged, and professional.Key Features4-bus mixer featuring high-headroom, low-noise designBoutique-quality Onyx microphone preamps
