Mackie 1604VLZ4 16-Channel 4-Bus Compact Mixer

A legend in compact mixer design, the 1604VLZ4 now combines the proven performance of Onyx preamps with the no-compromise high-headroom/low-noise design that has made the 1604 an industry mainstay.

All 16 channels feature an Onyx mic pre, line input and insert in a compact 4-bus design built for application flexibility and professional performance. Plus, it is truly "Built-Like-A-Tank" with a ridiculously rugged solid-steel chasis that includes high-contrast controls for ultimate tactile control.

Found in countless professional broadcast and post facilities and easily the most proven band-friendly analog mixer ever, the 1604 stands alone in the world of compact mixing.
