Mackie Onyx24: The Premium Analog Mixer Built to Record

The Mackie Onyx24 is a 24-channel (24x4) premium analog mixer with built-in multitrack USB, pairing 18 award-winning Onyx microphone preamps, a 3-band Perkins "British Style" EQ, a high-resolution Dynamic FX engine, and 24-bit/96 kHz recording in a Built-Like-A-Tank steel chassis. It sends every channel to your DAW over a single USB cable and captures a stereo mix straight to an SD card, so the same board anchors a studio session and a live show. For the engineer who refuses to choose between analog feel and modern workflow, it is the centerpiece a serious rig has been waiting for.

Eighteen Onyx Preamps That Stay Clean

The heart of any console is its front end, and the Onyx24 leads with 18 low-noise Onyx microphone preamps that deliver up to 60 dB of clean gain with an equivalent input noise of -128 dBu and total harmonic distortion under 0.01 percent from the mic input to the main out. That headroom lets a quiet ribbon mic and a screaming guitar cabinet share the same board without hiss or grit, and switchable 48V phantom power on every mic channel drives studio condensers directly. The result is the rich, transparent capture that made the Onyx name, ready for a full drum kit, a choir, or a theatre pit.

Perkins EQ: Classic British Tone, Refined

Onyx24 channels carry an enhanced 3-band Perkins "British Style" EQ modeled on the Wien Bridge circuit topology of the hallowed consoles of the 1960s and '70s. Designer Cal Perkins traded a touch of raw boost for a wider, more musical Q, then reclaimed an extra 6 dB of range so each band swings a full plus or minus 15 dB without turning peaky. Low sits at 80 Hz and High at 12 kHz, while the mono channels add a sweepable midrange from 100 Hz to 8 kHz to pinpoint problem frequencies. A hard-bypass switch drops the EQ out of the signal path entirely so you can hear exactly what it is doing.

Multitrack Recording, No Interface Required

The Onyx24 is a class-compliant USB 2.0 audio interface as well as a mixer: connect it to a Mac or PC and record every channel at resolutions up to 24-bit / 96 kHz straight into your DAW. A channel-assignable 4-track USB return brings two stereo pairs back into the board for overdubs and playback, and a dedicated switch sends the finished main mix to USB. When a computer is not welcome, a full stereo mix records and plays back directly from an SD card at the same 24-bit / 96 kHz resolution, so you can track an album or capture a live set with nothing but the mixer.

Studio Command and a Powerful FX Engine

A high-resolution Dynamic FX processor puts a deep collection of reverbs, delays, and modulation effects on the board, each tunable through multi-parameter adjustment and a dedicated equalizer. You drive it all from Studio Command, a full-color LCD with real transport controls that recalls up to six customizable presets from a single intuitive knob, browses SD files, and manages recording without menu diving. Bluetooth streaming pairs a phone or laptop to compare reference tracks or pipe in walk-in music, routing the wireless audio to the aux sends or straight into the main mix.

Built for the Studio Floor and the Big Stage

Every detail of the Onyx24 is engineered for real work: a rugged steel chassis and sealed rotary knobs shrug off dust and spills, QuickGrip side handles make a hefty 24-channel board easy to carry between gigs, and vibrant backlit Mute and Solo buttons keep the mix readable in the darkest venue. Two aux/monitor sends with per-channel level, dedicated control room and headphone outputs, PFL/AFL solo, and a footswitch input for FX mute give you the routing muscle that live sound and multitrack tracking both demand.

Who the Onyx24 Is For

Recording studios tracking full bands, houses of worship and theatres running large input lists, and touring engineers who need one board for front-of-house and multitrack capture all reach for the Onyx24. Bundled with the Waveform OEM DAW and the 16-plug-in DAW Essentials Collection, it arrives ready to record the moment it is out of the box - a premium analog console with the recording power of a modern interface built right in.
