Mackie ProFX12v3+ Mixing Desk

Mackie ProFX12v3+ — Analog Mixer With Studio-Grade USB and Bluetooth

The Mackie ProFX12v3+ combines a 12-channel analog front end with a 24-bit / 192 kHz USB-C audio interface, giving hybrid studios one desk for live shows, livestreams, and multitrack recording. Seven Onyx preamps provide up to 60 dB of ultra-low-noise gain, while 3-band EQ and one-knob compression on channels 1–4 handle core sound shaping.

What Sets the ProFX12v3+ Apart

Inside the upgraded GigFX+ engine of the ProFX12v3+, the full-color LCD lets players edit decay, size, and high-cut on 24 effects and save custom presets. Bi-directional Bluetooth on a dedicated channel brings in phone guests without adapters, while loopback mode captures computer audio alongside the mixer signal for streaming.

Onyx Preamps and Analog Channel Strip

Built around seven Onyx mic preamps, the ProFX12v3+ front end handles condenser and dynamic microphones with up to 60 dB of ultra-low-noise gain. Each mic channel includes a 100 Hz low-cut filter and 48 V phantom power.

• Onyx Mic Preamps: 7 channels, up to 60 dB gain — clean, transparent headroom for vocals, drums, and acoustic instruments
• 3-band EQ on every channel — high, mid, and low shaping without menu diving

GigFX+ Engine and USB-C Recording Modes

The ProFX12v3+ ships with the GigFX+ engine loaded with 24 effects including Hall Reverb, Plate, Chorus, Flanger, Delay, and Slapback, editable via the full-color LCD. The 2x4 USB-C interface captures audio at 24-bit / 192 kHz with three recording modes.

• Effects Engine: GigFX+ with 24 presets, full-color LCD — edit decay, size, and high-cut in real time and save custom presets
• USB-C Interface at 24-bit / 192 kHz — pristine multitrack capture for studio and live recording

The ProFX12v3+ offers XLR / TRS combo jacks on channels 1–2, XLR inputs on 3–7, line inputs on 3/4 through 9/10, and a stereo 1/8" input on 11/12. FX, monitor, and subgroup busses plus a footswitch jack handle routing.

Who Should Choose This Mixer

The ProFX12v3+ is the right choice for solo artists, podcasters, and small bands who need one desk for live mixing, multitrack recording, and livestreaming. Houses of worship, schools, and event venues get a road-ready console with enough mic inputs for a full band or panel discussion.

Mackie — Built-Like-A-Tank Since 1988

Mackie has designed professional audio gear in Woodinville, Washington since 1988, building a reputation for compact mixers that survive years of road use. The ProFXv3+ series continues that legacy with a solid steel chassis, ABS side protection, and the Built-Like-A-Tank promise, plus the Waveform OEM DAW, DAW Essentials Collection, and a locking power adapter.
