Mackie PROFX12 V3 Helimikser

12-Channel Analog USB Mixer for Live and Studio Use

A 12-channel analog USB mixer that handles every source cleanly gives you a reliable foundation for live gigs, podcasts, and home studio tracking. The Mackie PROFX12 V3 combines seven Onyx mic preamps, a 24-effect GigFX engine, and a 2x4 USB audio interface into a single rugged chassis. Musicians and content creators use this board to capture high-resolution audio at sample rates up to 192 kHz while keeping the workflow hands-on and immediate.

GigFX Effects Engine and Built-In Dynamics Control

What sets this mixer apart from competing analog boards is the combination of a 24-effect GigFX processor and four dedicated one-knob compressors on channels 1 through 4. The effects library spans reverbs, delays, choruses, and a delay-plus-reverb preset handy for vocalists wanting both spatial depth and rhythmic echo from a single knob. Mute effects between songs using a footswitch, so you never have to reach for the board mid-set.

Onyx Mic Preamps and Input Architecture

Clean gain staging is the foundation of any mix. Seven low-noise Onyx mic preamps deliver up to 60 dB of gain—more than enough for demanding dynamic microphones without introducing hiss.

• Mic Preamps: 7 Onyx preamps, 60 dB gain — both low-output dynamics and condensers are managed with ease
• Phantom Power: 48 V on all mic channels — designed for condenser microphones in studio and live settings
• Plug guitars and basses straight in using the Hi-Z switchable inputs on channels 1 and 2—no DI box required.
• Low-Cut Filter: 100 Hz per channel — removes stage rumble, handling noise, and HVAC hum before it reaches the mix

Three-Band EQ and Channel Compression

Each channel is equipped with a three-band equalizer and a hard-bypass switch to allow instant comparison between processed and unprocessed sound.

• EQ Bands: High 12 kHz, Mid 2.5 kHz, Low 80 Hz — shape your sound across the full spectrum for any input
• Compressors: 4 one-knob compressors on channels 1–4 — tame vocal peaks and even out instrument dynamics with no need for extra rack gear
• Channel Inserts: Available on channels 1–4 — integrate external processors such as gates or graphic EQs with ease

USB Recording and Routing Flexibility

The USB interface serves as both a live mixer output and a recording interface, doing away with the need for a dedicated audio interface.

• USB Audio Interface: 2x4 I/O at 192 kHz / 24-bit — stream a stereo mix to your DAW while returning two independent channels for playback or backing tracks
• Direct Monitoring: Latency-free with blend control — real-time balance between live input and DAW return
• Subgroup Bus: Stereo subgroup with per-channel assignment — group background vocalists or drum mics for unified level control
• Feed stage monitors or an in-ear mix independently from the main output with the two aux/monitor sends and individual channel control.

Built for Live Performers, Podcasters, and Home Studio Engineers

For small bands managing their own PA, a compact mixer that fits in a carry bag yet handles every source is essential. Podcasters and streamers make use of the USB interface and latency-free monitoring, eliminating the echo that plagues software-only solutions. The PROFX12 V3 is the right choice for content creators in need of a single device that serves as both live mixer and recording interface. Houses of worship, school auditoriums, and rehearsal spaces can take advantage of the internal power supply with a standard IEC connector—forget unreliable external power bricks. With Waveform OEM DAW and the DAW Essentials Collection of 16 plug-ins included, you’re ready to record right out of the box with just a laptop and a few cables.

Mackie — Decades of Professional Audio Design

Founded in 1988 in Woodinville, Washington, Mackie built its reputation on mixers that survive the road. The ProFX series has become one of the world’s top-selling analog mixer lines, and the V3 generation continues that legacy with upgraded Onyx preamps, a higher-resolution USB interface, and an expanded effects engine.
