6 Mic Preamps + 3 Stereo Channels

Six mic/line inputs with DuoPre mic preamps (with 69 dB gain) handle your microphones and DI boxes. Three dual-stereo channels, each with gain control and 2-band EQ, have your back for line-level stereo sources like keyboards or audio players. Each stereo channel offers a main stereo input on jack sockets with additional inputs from phono sockets or from the USB audio input. You can select the USB return to one of the extra inputs so that it feeds either the main LR bus or the stereo channel.

Internal FX to Sweeten Your Sound

What sets the ZED-12FX apart from other mixers in its class is its impressive FX section. The mixer sports 16 digital effects ranging from delays and reverbs to flanger and chorus. On each effect, there's a tweakable parameter for dialing in your sound. Five of the effects even support tap tempo. These ZED FX are controlled using three buttons and nine LEDs, which are easy read more to view in the darkest of rooms. Sweeten your sound even more with the ZED-12FX's musical 3-band EQ with MusiQ.

USB Interface Lets You Mix, Record, and Play Back Music

Allen and Heath ZED-12FX Mixer

Complementing the existing ZED series, the ZED FX has been developed around an FX chipset purely for this model. Allen and Heath's DSP engineers have been working hard, crafting and refining beautiful reverb algorithms. The effects are available nowhere else -- this quality and integration is only available from the ZED FX.

16 essential time-delay effects add to the already bulging feature set. The mixer is ideal for small groups who don't want to carry around an effects unit with their gear but who still want great quality FX at their gigs and on their recordings.

In addition to the DuoPreTM mic pre-amps, 100mm faders and MusiQ EQ section which are shared with the whole ZED range, the ZED FX has 16 unique effects, designed by Allen and Heath's DSP team, in Cornwall.


ZED FX are easily controlled using 3 buttons and 9 LEDs. Quickly tap the ideal delay time or 'dial-in' the perfect amount of reverb on the lead vocal. One-stop navigation and editing. In fact, just as easy as your effects pedals. Hold down the TAP button and press the up or down button to alter the effects parameter, for example on patch (9) Plate, this would adjust the decay length. The ZED FX is designed to fulfill all the functions a small band would need without their own sound engineer. The layout and features have been arranged to be logical and instantly recognizable at a dark gig -- a mixer you can trust to perform.

The USB audio interface, with its uniquely flexible capability, allows different signals to be sent to USB, from LR or from selected aux buses. The USB return signal can be routed straight to the LR mix or to a stereo channel. The connectors are placed on the top surface for easy plugging & patching, and the construction, with individual circuit boards firmly nutted to the top panel, is as rock solid as Allen & Heath's top of the range ML Series mixers.

The ZED FX range currently comprises of the ZED12FX and the 22FX. Between them they offer a solution for any small group or singer songwriter needing up to 16 mono inputs and 3 stereo inputs. Keyboards, microphones, samplers, the sky is the limit. Each mono channel has an insert point, allowing in-line effects such as compressors to be added to the signal chain, just like A&H's large-format mixers.

Internal FX

16 separate effects have been crafted into the ZED-FX range. These include Delay and Reverb, Ping-Pong delay, a selection of reverbs with different room/hall/arena properties, a flanger and a chorus. All have been designed to complement the material the engineer is working with. Each of the effects has a parameter which can be altered: pre-delay can be adjusted, room sizes tweaked, and flanger speed dialled-in. Five of the effects can have their tempo tapped in, and the output auditioned by the FX PFL.


One of the great things about the ZED series is the number and variety of things you can plug in. In addition to the six mono channels there are three dual stereo channels, each with a main stereo input on jack sockets, and with the ability to take additional stereo inputs from phono sockets or from the USB audio input, flexibility gives you control. 6 mic/line channels are provided on ZED12FX -- plenty for mics or DI boxes for a small band, duo or solo performer 4 stereo line inputs -- dual inputs, both with gain and 2-band EQ


Based on the proven pre-amps from the hugely successful PA series, the ZED series has DuoPreTM pre-amps, which use a two stage design, with carefully controlled amounts of gain in each stage. When amplifying the signal from the XLR input, the gain range is huge -- 69dB of range to be exact - and is very evenly distributed around the gain control, meaning better control of signal level. Most of the gain comes from the first stage, so unwanted noise is kept to a minimum. Line level signals are simply plugged into the second stage of the pre-amp by using the line input jack socket, which has the great advantage of less noise when using the line input.

EQ section

ZED-FX features a musical 3-band EQ derived from the acclaimed GL2400 mixer.
The design utilises MusiQ -- optimised slope (or Q factor) for equalising individual instruments.

Auxiliary sends

4 aux sends are provided, of which 1&2 are prefade for foldback monitoring, and 3 & 4 post-fade for effects sends. A stereo signal can be sent from auxes via USB to computer to create 2 separate record feeds independent of the main LR mix (1&2) and or used as FX sends (3&4).

USB audio flexibility

Getting audio to and from a computer easily is now a common requirement for live sound and music production. The way A&H have implemented this on ZED is super-flexible and super-easy! No longer do you need to fiddle around the back of your PC to get to the soundcard inputs, only to find that the levels are all wrong and noisy. Just plug in a USB lead to your ZED, select the USB routing on the mixer and the device on your computer and that's it! Quality audio to and from your PC or Mac. Three switches provide different send/return configurations for recording, playback and utilizing external FX.


The ZED12FX has been designed using individual vertically mounted circuit boards with each rotary control fixed with a metal nut to the front panel -- making a much more robust product that will resist damage and give years of reliable use. ZED also has professional 100mm faders for ultimate control over your levels.

Sonar LE

Allen and Heath have teamed up with Cakewalk to bundle Sonar LE with this ZED mixer. The two team up together in many ways -- for example straightforward recording of a stereo mix, recording tracks individually to build up a song, or for inserting a Sonar LE effects plug-in.

I have used Mackie mixers for 13 years now and that mixer lasted the 13 years since I bought it. This mixer, the way it feels and performs, should last me till it dies. Even if it does dies on me, you know I'll be getting another one to replace it in a heartbeat.
I have used Mackie mixers for 13 years now. This is the first mixer other than Mackie that I have used, and I have to say, I wished that I have bought Allen & Heath years ago. This is by far the best mixer I have ever played through. The sound is transparent and silky smooth. The effects are like butter and is a pleasure playing every night with the mixer.
For what I need it for, you can't beat what it has to offer. I am just a solo guitarist, and for my needs, it's the best. I did a trio last night and worked very well. The other 2 musicians were in awe with the smoothness and the sound clarity of this board.
Ease of Use
Very easy, and straight forward.
This mixer is built and feels like a tank. Everything from the knobs to the sliders feels like it was made to stand time and usage. Very well built.
For the price, I don't think you can find a better mixer with what it offers. Allen & Heath really outdid themselves when designing this mixer.

The Wow Factor
The color and aesthetics of this mixer looks great. I love the color coordination of the sliders and knobs. You won't get confused with all knobs being black and searching up and down for what you need.
