The VLZ4 design goal was simple: every VLZ4 mixer must have the highest headroom and lowest noise possible. Plus it truly is "Built-Like-A-Tank" with a rugged solid steel chasis and high contrast controls for ultimate tactile control. And with features like instrument level inputs, phantom power and level metering, the 1642VLZ4 offers a true step up performance and durability that's ideal for your professional application.VLZEach generation of VLZ mixers benefits from a reinvestment in performance, all without raising prices. By continuing to ignore the “race to the bottom,” VLZ4 benefits from generations of performance improvements like transparent EQ, class-leading negative summing bus architecture and custom-designed op-amps to ensure signal integrity from every input to every output. The result is a mixer that is at the peak of performance and is the obvious go-to compact analog mixer for engineers who demand professional results.OnyxThe performance of Mackie’s Onyx mic preamps is more than proven.
