Mackie ProFX16v3 16-Channel USB Analog Mixer

The Mackie ProFX16v3 is a 16-channel professional analog mixer with a built-in USB recording interface and onboard effects. It brings microphones, instruments, stereo playback sources, monitoring, and computer audio together in one hands-on console. It is suited to small live-sound systems, rehearsal spaces, home studios, streaming rigs, and production setups that need more source capacity than a compact mixer provides.

Its eleven Onyx microphone preamps provide up to 60 dB of gain for dynamic, condenser, and other compatible microphone sources. Channels 1 and 2 add switchable Hi-Z operation for direct connection of guitars, basses, and similar instruments without a separate DI box. Built-in single-knob compression on channels 1 through 8 helps manage changing vocal, speech, and instrument levels before they reach the mix.

The ProFX16v3 uses a practical analog workflow with gain controls, channel EQ, routing assignments, mute switches, PFL solo, and long-throw faders. Its 3-band EQ includes a sweepable mid-frequency control on channels other than the 1/8-inch stereo input channel. A 100 Hz low-cut filter and EQ bypass capability provide useful tools for shaping sources and simplifying setup.

For computer recording and playback, the integrated USB 2.0 interface supports 24-bit conversion at sample rates up to 192 kHz. The 2x4 USB design records a stereo signal to a computer while returning two independent stereo playback streams to the mixer. A dedicated blend control supports direct, latency-free monitoring alongside DAW playback during overdubs.

The onboard GigFX engine provides 24 selectable effects presets, including room, hall, plate, chorus, delay, flange, auto-wah, and other processing. Three aux outputs support separate monitor mixes, while four subgroup outputs expand routing for larger setups and external devices. Main outputs, control-room outputs, headphones, inserts, USB connectivity, and an external FX footswitch connection make the mixer adaptable as a central control point for a growing audio system.

Design & Installation

The ProFX16v3 uses a rugged, desktop-format mixer chassis with a clearly organized control surface, channel faders, dedicated master controls, and dual 12-segment main meters. Mackie does not specify a chassis-material designation, but the design is intended for regular studio, rehearsal, and live-production use. Main output connections are located on the rear panel, keeping system cabling organized around the mixer.

Connect microphones, line-level sources, and instruments before powering the mixer, then feed powered speakers, amplifiers, or processors from the main outputs. Use the three aux outputs for monitor systems, the control-room outputs for studio monitors, and the headphone output for personal monitoring. The mixer uses a detachable 3-pin IEC power cord and can connect to a Mac or PC through USB; optional rack ears are available separately for rack installation.
