The Mackie ProFX16v3 is a 16-channel professional audio mixer that integrates a comprehensive suite of onboard digital effects, multi-channel USB audio interfacing, and a flexible 4-bus architecture into a single, robust console designed for live sound, recording, and streaming applications. This mixer provides a versatile platform for musicians, DJs, podcasters, and houses of worship to manage multiple microphones, instruments, and line-level sources with professional control and sonic quality. Each of its channels features Mackie's renowned Onyx mic preamplifiers, which deliver high headroom and low noise for clear, detailed sound capture. The mixer's intuitive layout includes 3-band EQ with sweepable mids on most channels, allowing for precise tonal shaping of individual inputs, while dedicated monitor, aux, and subgroup sends offer extensive routing flexibility for stage monitors, external effects processors, or subgroup mixing.

A central feature of the ProFX16v3 is its built-in digital effects engine, which provides 24 professional-grade DSP effects including reverbs, delays, choruses, and pitch correction, accessible via a dedicated section with depth and parameter controls. The USB audio interface functionality is a significant asset, enabling the mixer to act as a 16x4 computer audio interface for multi-track recording or stereo streaming, allowing users to record each channel discretely to a DAW or send a stereo mix to streaming software without the need for an external interface. The mixer also includes a dedicated stereo USB/2-Track return with level control, making it easy to integrate computer playback or recorded tracks into the live mix.

Built into a rugged steel chassis with tactile, responsive controls, the ProFX16v3 is designed for reliability in both stationary and mobile use. It features XLR and balanced 1/4-inch main outputs, independent monitor outputs, and a headphone amp with cue mixing. The inclusion of a one-knob compressor on the first two channels helps manage dynamic sources like vocals or bass guitar quickly and effectively. By combining high-quality analog preamps, flexible routing, integrated multi-effects, and seamless USB connectivity, the Mackie ProFX16v3 serves as an all-in-one production console that empowers users to handle complex audio mixing tasks for live performance, recording, and broadcast with confidence and efficiency.
