The Mackie ONYX24 is a premium 24-channel analog mixer that combines the warmth and immediacy of analog signal processing with the advanced capability of multi-track USB recording, catering to professional studios, live sound venues, and complex project studios. It is built around Mackie's renowned ONYX microphone preamplifiers across all 16 mono input channels, delivering ultra-low noise, high headroom, and transparent sonic character for a wide range of microphones and instruments. The mixer features a comprehensive 4-bus architecture with eight auxiliary sends, four subgroup outputs, and a flexible routing matrix, providing extensive control for live mixing, broadcast, and studio production. Its robust, all-metal chassis and intuitive layout with 100mm faders ensure both durability and efficient workflow management during demanding sessions.

A defining feature of the ONYX24 is its integrated high-resolution multi-track USB audio interface, which allows all 24 input channels (including the stereo returns) to be recorded simultaneously as discrete tracks to a computer. This capability makes it an exceptional hub for capturing live performances or multi-instrument studio sessions in pristine quality without the need for an external interface rack. The USB connection also provides stereo playback from the computer to the mixer's main outputs or dedicated control room/headphone feeds, facilitating overdubs and mixdowns with near-zero latency monitoring. This seamless integration bridges classic analog mixing with modern digital audio workstation workflows, offering unparalleled flexibility.

The mixer is equipped with extensive professional features, including 3-band EQ with sweepable midrange on mono channels, high-pass filters, and pre-EQ channel inserts. It boasts a dedicated monitoring section with separate control room and studio outputs, two independent headphone amplifiers, and a talkback microphone input for studio communication. By merging high-quality analog components, flexible routing, and advanced multi-track digital interfacing, the Mackie ONYX24 serves as a powerful and versatile nerve center for audio professionals who demand both the sonic integrity of analog and the convenience and power of computer-based recording and production.
