The Mackie MCK-2040766-00 1642VLZ4 is a professional 16-channel compact mixer that represents a significant evolution in the renowned VLZ series, known for its pristine preamplifiers and robust build quality. This model is engineered to serve as the central nervous system for sophisticated live sound, project studio recording, and complex multimedia presentations, offering a comprehensive channel count within a remarkably efficient physical footprint. The mixer features Mackie's signature Onyx microphone preamplifiers across all mono channels, which are designed with high headroom and ultra-low noise floors to deliver transparent, detailed audio from a wide variety of microphones and instruments. This professional-grade preamp performance ensures that subtle sonic details are preserved, whether amplifying a delicate acoustic performance or driving powerful vocal takes in a live setting.

The mixer's architecture is built around a flexible 4-bus design, comprising stereo main Left/Right outputs along with two additional auxiliary mixes. This provides immense routing flexibility, allowing separate monitor sends for performers, connections to external effects processors, or creation of discrete sub-mixes for recording or zone-specific sound reinforcement. Each of the 12 mono input channels is equipped with a comprehensive 3-band EQ with swept midrange, a high-pass filter, and pre-fader aux sends, while the four stereo channels offer dedicated 2-band EQ for line-level sources like keyboards or playback devices. The inclusion of dedicated stereo USB audio interface functionality is a key modern feature, enabling direct 16x4 digital recording to a computer and playback back through the mixer, seamlessly bridging the analog and digital domains for hybrid workflows.

Housed in the iconic VLZ all-steel chassis, the 1642VLZ4 is constructed to withstand the rigors of regular transport and heavy use. The intuitive layout, with its clear visual feedback and responsive controls, promotes rapid operation during dynamic live events. Additional professional features include multi-channel digital effects, robust solo and mute functions, and comprehensive metering for accurate level management. For the working audio professional, this mixer delivers a compelling combination of premium analog sound, extensive connectivity, digital integration, and road-ready durability, making it an indispensable tool for demanding applications where reliability and audio fidelity are paramount.
