Description
The Allen & Heath ZED-12FX is a 12-channel multipurpose analog mixer built for live gigs and studio recording, with six mic/line inputs, three stereo channels, and 69 dB of preamp gain. It features 16 built-in digital effects—such as reverbs, delays, flanger, doubler, and chorus—for creative processing on every channel. Thanks to its 2-in / 2-out USB interface, you can record and stream your performance with flexible routing via main mix or aux sends. Each channel offers a MusiQ 3-band EQ with sweepable mids, plus high-pass filters on mono channels for clean and controlled tonal shaping. The mixer includes four Aux/FX sends for external monitoring or effect integration, along with 100 mm faders for smooth, precise control. Ruggedly built with vertically mounted channel boards and durable components, the ZED-12FX holds up to the demands of both live sound and travel.

Flexible Stereo USB Recording
The ZED Mid features a 2-in/2-out USB interface for flexible routing of Main Mix L+R or Aux 1–4 to your DAW, with the stereo USB return coming back on a dedicated channel for seamless monitoring and playback, allowing easy recording of live sets or rehearsals and smooth playback of backing tracks.

Integrated FX Engine
The ZED Mid series includes 16 built-in effects such as reverb, delay, and modulation designed by Allen & Heath’s in-house team. These effects are crafted to enhance vocal and instrument clarity in live or studio settings. Each preset can be dialled in quickly to add depth and polish to any performance.
