Mackie PROFX12V3 Overview

The Mackie ProFX12v3 is a 12-channel mixing console featuring seven Onyx microphone preamps with 60 dB of headroom and a built-in effects engine with 24 built-in FX, making it well suited for live sound, home recording, and content creators. The integrated 2x4 USB audio interface offers high-quality 24-bit / 192 kHz recording and playback with zero-latency monitoring.

Channels 1-2 offer combo XLR-1/4" mic/line connections and a Hi-Z switch (for guitar and bass), while channels 3-4 offer XLR or 1/4" inputs. Channels 1-4 include inserts, and single-knob compression. Channels 5/6, 7/8, 9/10 offer two 1/4" inputs, while channel 11/12 uses a 3.5mm stereo input. Channels 1-10 feature gain controls, a 3-band EQ, an aux (monitor) send, a dedicated FX send, pan, mute, and level faders. Engaging channel 11/12's USB 3-4 switch will override the 3.5mm input and enable the USB return from a computer. 

Each channel strip includes button selectors for Main L/R, Sub 1/2, and Solo (PFL). The master section offers dedicated faders for Main, Sub, and FX. Main output connectors include both XLR and 1/4", while sub and control room outputs use 1/4" connector. A dedicated 1/4" TRS headphone output includes its own independent level control. Other features include an input / USB 1-2 blend control, a dedicated FX output, an FX level fader, and an FX mute, which can also be controlled via the 1/4" footswitch input.

Everything was packaged correctly!! Product was just as summarized! Everything I have ordered from B&H always have been packaged with care. I will order from this company again!!

Good mid-sized option, just the right number of inputs

By Michael

I have both the 6 and the 16, but needed something mid-sized for a standard show. This has nearly all of the functions of the 16 with a smaller footprint in my DJ case. A selling point that puts this above the 10 is that the channel faders are sliders, not knobs.

Is the USB output of this board in stereo? The USB output of the v2 was mono mix
Asked by: Mark
I have 3 of the V2 boards, and their USB out is decidedly mono mixdown, not separated stereo. I hope v3 does fix this. I had to purchase a Scarlett to put after the v2 boards I have to get true stereo to my computer.

How many inputs will be available on my DAW when using the USB function?
Asked by: Bryan
This mixer has just 4 USB out channels, which is basically two stereo pair. If you are recording a small ensemble or solo artist this may be ok, but it is really not intended to be a full fledged multi-channel interface, rather a live board with the ability to record a live mix, or stream. If you are interested in something that might be good in both a live situation where you need a lot of inputs an routing capabilities, yet wish to record tracks to your DAW, consider the Tascam Model 12. It is a hybrid 12/10 io USB interface built in to a nice 12-channel live board. https://www.bhphotovideo.com/c/product/1539340-REG/tascam_model_12_mixer_intrfc_recordr_controlr.html

Does this mixer allow for a mix minus?

Does this mixer allow for a mix minus?
Asked by: Mark
Unfortunately not; the Mackie ProFX12v3 12-Channel Mixer does not feature a dedicated mix-minus channel.
