The Mackie MCK-2051302-00 ProFX16v3 is a 16-channel professional mixer that integrates a comprehensive feature set for live sound reinforcement, recording, and streaming applications. It provides a flexible input layout with sixteen channels, each equipped with Mackie's renowned Onyx microphone preamplifiers known for their high headroom and transparent sound quality, making them suitable for a wide variety of microphones and instruments. The mixer is structured around a 4-bus design, offering separate control over main mixes, monitor sends, and subgroup outputs, which provides sound engineers with greater routing flexibility for managing different sections of a band or creating separate mixes for monitors and front-of-house. This architecture, combined with dedicated stereo channels for line-level sources, makes it a capable centerpiece for small to medium-sized venues, houses of worship, and project studios.

A standout feature of the ProFX16v3 is its built-in digital effects processor, offering 16 professional-grade effects presets including reverbs, delays, and choruses that are easily accessible and assignable to any channel via dedicated send controls. The inclusion of a USB audio interface expands its functionality significantly, allowing for direct multi-track recording to a computer or digital audio workstation (DAW), as well as the playback of stereo audio from a computer back through the mixer. This makes it an excellent tool for podcast production, live streaming, and capturing high-quality live recordings without the need for an external interface. The mixer also includes a dedicated talkback microphone and a built-in slate tone generator, streamlining communication with performers during setup and providing reference tones for level calibration in recording scenarios.

Designed for both durability and user-friendly operation, the mixer features a robust steel chassis, responsive 60mm faders, and clearly labeled controls laid out in an intuitive workflow. The one-knob compressors on the first four microphone channels help manage dynamic sources like vocals effortlessly, while the three-band EQ with sweepable midrange on all mono channels offers precise tonal shaping. The Mackie ProFX16v3 successfully bridges the gap between analog mixing simplicity and modern digital connectivity, offering musicians, engineers, and content creators a versatile and reliable audio hub that enhances live performances, facilitates high-quality recordings, and supports professional streaming broadcasts with a single integrated unit.
