The 3204VLZ4's full set of processors lets you travel "rack free" while still making professional sounding mixes.

Mackie relentlessly pursues the perfection of the compact mixer. VLZ4 ups the level of sonic quality at every level, featuring Mackie's flagship Onyx mic preamps and premium components from front to back. The result is the most rock solid, the most easy to use and the best sounding compact mixer ever created. From every input to every output, VLZ4 is optimized to deliver professional-quality results each and every time.

Two of Mackie's patented Running Man FX processors (RMFX+™) are right on the board, providing 24 "gig-ready" effects. Not wasting space on useless effects, these offer a suite of quickly accessible and useable reverbs, choruses and delays that make coloring your mix a breeze.

Additionally, both FX processors feature a tap delay, typically only available on an outboard rack. Delays may easily be sync'd with the song at the tap of a finger. And to accommodate flexible routing, the processed signal may be sent direct to the mains and monitors from the effects section or re-routed to the two stereo channels to bring them through the EQ and aux section, utilizing the 60mm fader to draw them into the mix.

The VLZ4 4•Bus has 8 single knob compressors to stop the dynamic signals from poking out of the mix. Four compressors are located on the last four mic inputs so that the most critical signals (like vocals and snare drum) may be addressed. Plus, there are single knob compressors on each of the four subgroups so that grouped signals (like drum set or choir) may be blended together for ultimate smoothness.

The VLZ4 4•Bus Series Mixers also feature a 4x2 USB recording and playback function. This means up to four signals may be recorded simultaneously and a stereo mix returned to the mixer for playback.
