32-ch Analog Mixer with 28 Onyx Mic Preamps, 6 x Aux Sends Per Channel, 4 x Mix Buses, Built-in Effects, and 4x2 24-bit USB Audio Interface. Beyond sounding great, the Mackie 3204VLZ3 mixer is one piece of gear you can truly rely on.

The 3204VLZ3 also boasts effects DSP with two internal FX sends, and even a 4 x 2, 24-bit USB audio interface for easy, high-quality recording. And with high-resolution meters, generous I/O, and sealed rotary controls that keep out dust and grime, the Mackie 3204VLZ3 is one of Mackie's best mixers ever.
