The Mackie ProFX22v3 is a medium-format analog mixer designed for live sound, recording, and complex audio production tasks where multiple input sources and flexible routing are required. It features 22 input channels, combining a combination of mono microphone/line inputs with stereo line inputs, providing ample connectivity for microphones, instruments, and playback devices. A central component of its design is the integrated professional-grade effects processor, which offers a selection of studio-quality digital effects such as reverbs, delays, and choruses that can be applied to individual channels or groups via dedicated sends. The mixer's 4-bus architecture, comprising 4 subgroup outputs and a stereo main mix, allows for sophisticated routing options, enabling the operator to group related channels (like all drum mics or background vocals) for balanced subgroup mixing before sending them to the main output, which is essential for managing complex mixes efficiently.

The channel strips are designed for clarity and control, each featuring a 3-band EQ with sweepable mid-frequency for precise tonal shaping, along with high-pass filters to eliminate low-frequency rumble. Each mono channel includes a switchable +48V phantom power for condenser microphones, along with dedicated level controls for the two internal effects sends and the four subgroup assigns. The mixer also incorporates a built-in USB audio interface, enabling direct stereo recording of the main mix or subgroups to a computer, as well as playback of stereo audio from a DAW back through the mixer, making it a versatile hub for both live performance and studio work. The rear panel is comprehensively outfitted with balanced XLR main outputs, balanced 1/4" subgroup outputs, and a variety of auxiliary sends and returns for connecting outboard gear.

Built with Mackie's reputation for durability, the ProFX22v3 features a robust steel chassis and responsive, long-life faders and potentiometers. The intuitive layout, combined with clear visual metering via 12-segment LED meters for the main and subgroup outputs, ensures that operators can confidently monitor levels and avoid clipping. This mixer is well-suited for applications such as house of worship sound, live music venues, band practice, and project studio recording, providing a comprehensive set of professional features in a reliable and user-friendly analog format with the added convenience of digital effects and USB connectivity.
