Complementing the Allen & Heath's ZED series, the ZED-12FX and its fellow FX series mixer have been developed around an FX chipset. Allen & Heath's DSP engineers worked hard, crafting and refining beautiful reverb algorithms. The 16 effects they created are available nowhere else-this quality and integration is only available in the ZED FX series. 16 essential time-delay effects add to the already bulging feature set. The ZED 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, the ZED-12FX USB mixer gives you DuoPre mic pre-amps, 100mm faders, and the MusiQ EQ section which are shared with the whole ZED range.

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 dialed-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 Allen & Heath's ZED series is the number and variety of things you can plug in. In addition to the mixer's 6 mono channels, there are 3 dual stereo channels, each with a main stereo input on the jack sockets, and with the ability to take additional stereo inputs from phono sockets, or from the USB audio input. 6 mic/line channels are provided on the ZED-12FX-plenty for mics or DI boxes for a small band, duo, or solo performer, as well as 4 stereo line inputs-dual inputs, both with gain and 2-band EQ.

Based on the proven preamps from their PA series, Allen & Heath's ZED series has DuoPre preamps 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 preamp by using the line input jack socket, which has the great advantage of less noise when using the line input.

EQ section

The ZED-12FX USB mixer 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 L/R 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 this has been implemented on the ZED FX mixers is flexible and 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 mixer, select the USB routing on the mixer and the device on your computer, and that's it. Three switches provide different send/return configurations for recording, playback, and utilising external FX.


The ZED-12FX 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. It also has professional 100mm faders for ultimate control over your levels.

SONAR LE included
Allen & Heath teamed up with Cakewalk to bundle SONAR LE with the ZED 12-FX mixer. The two work together in many ways, from straightforward recording of a stereo mix to recording tracks individually to build up a song, or even for inserting a SONAR LE effects plug-in.

ZED FX Series
ZED FX mixers 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. Talk about one-stop navigation and editing, it's just as easy your average 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 mixers are designed to fulfill all the functions a small band would need without needing their own sound engineer. The layout and features have all been arranged to be logical and instantly recognisable even at a dark gig to make it 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 L/R or from selected aux buses. The USB return signal can be routed straight to the L/R 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.

Great Mixer

By Mike

from South Portland Maine

Comments about Allen & Heath ZED-12FX USB Mixer with Effects:

So far I love this mixer!The vocals are crisp, the effects are clean and infinitely adjustable, and it's made with high quality components I know will stand up to the heavy use I put it through as a full time Disc Jockey.

It's worth every penny

By Duane Eby

from Fort Wayne, Indiana

Comments about Allen & Heath ZED-12FX USB Mixer with Effects:

I have never owned a piece of Allen & Heath equipment before this purchase...the quality of the mic pre's alone are worth the money...there are no more "mic vs line" gain problems...the PFL buttons are new to me also as is the sweepable midrange...I can get right at the sound of my guitar instead of "living with" whatever I could squeak out of my old mixer....and being able to hear selected channels through a headphone mix is invaluable. I wish I had this mixer 20 years ago! Also my local GuitarCenter personnel were very efficient and helpful (Eric).

gives off smell

By Howard Page

from Seabrook,NH

Comments about Allen & Heath ZED-12FX USB Mixer with Effects:

I bought one of these brand new and have only used it 4 times. using it primarily as a pa amp. I noticed after the first time it had a smell to it similar to burning electrical components. Saw no smoke, no heat,still working great. If only I could get rid of that smell. It is always cased when not in use so no dust or dirt inside. Really pumps out the volume.

Fantastic mixer - solid construction/great sound

By Chris Wilson

from Portland, OR

Comments about Allen & Heath ZED-12FX USB Mixer with Effects:

We use this mixer for an acoustic group that has three vocal mics, bass, mandolin and two guitars. It was easy to get up and running, sounds fantastic, and feels very solidly built. We've only had it for about a month, but we put it through two QSC K-10s and we couldn't be happier with the sound. We even have to push the pre-amp big time for the mandolin (the pickup on the mando is weak) and it still sounds great. The EQ is very nice (love the sweepable mids for gtr and mando). Overall, we feel like it's very transparent and yet rich, if that makes sense. The effects are very solid for live performance. It eliminates having to bring an external fx unit - we mainly only use reverb and it does nicely. If you need flexibility with your fx (i.e., you want delay on the guitar but not the vocals) it's easy to add an fx unit with the aux sends. We'll be using the USB out for recording our live performances but have nothing to report about the sound quality of the A/D converters at this time.

Very Nice!

By Jules Tarrant

from Lake Ridge, VA

Comments about Allen & Heath ZED-12FX USB Mixer with Effects:

I love this mixer. I've used Behringers in the past and this one beats the rest. Very low noise if any, even with effects. I selected this one based on the number of channels and the small selection of effects. I've used this to record a live band with great exporting results. Very easy to control parameters/equalization. Solidly built like a tank. Good looking. Very impressed. Effects are limited but why would you need 100 mediocre effects when just a few awesome ones will do the job.

Very clean sound

By Ken

from Amite, Louisiana

Comments about Allen & Heath ZED-12FX USB Mixer with Effects:

Very clean sound. I've got it running to a pair of Electro-Voice ZLX-12s & the entire system sounds super clean. I am especially impressed with its ability to add clarity and punch to the vocals. A vocalist dream! ... seems very sturdy and should last a long time. I haven't found the effects as effective as I would have hoped but I haven't spent a lot of time trying to find effects. Give me another month & I will know much more. I am happy wity the clean sound and I am glad I got an Allen & Heath. I've been playing 37 years and seem equipment come and go but this is by far the cleanest sounding system I have had or seen.

A Dueling Piano Mixer


from Hollywood, FL

Comments about Allen & Heath ZED-12FX USB Mixer with Effects:

I have a dueling piano show that I book frequently for corporate events and private parties. Hauling gear has been a real back breaker. This mixer is one of he items I bought to reduce my load. The board performs well in every aspect of my needs for a team of two piano players. The effects are limited, but excellent, and more than enough for any vocal setting I use. The mixer has three usable busses for monitors, one more than I need. (The fourth is a dedicated onboard effects bus. The signal is very clean and noise free, and the channels have enough EQ control that a graphic EQ is not needed. A great little lightweight board that fills all my needs. I ilke it.


I like everything about it
