The preamps on ZED Mid mixers provide a huge 69dB of gain, enough for low output dynamic microphones and quiet acoustic sources, while keeping noise and distortion to a minimum. Gain is evenly distributed throughout the gain control ensuring precision control at all levels.

Allen & Heath AH-ZED12FX - Multipurpose Mixer with FX
Allen & Heath AH-ZED12FX
The ZED-12FX is ideal for groups who need to travel light. Even with its small footprint, the 12FX squeezes in 4 auxiliary channels and swept semi-parametric EQ on top of the already impressive feature set including configurable USB audio in/out makes it easy to capture stereo recordings.
Integrated FX Add Depth With FX
The three ZED Mid FX models feature an essential selection of 16 reverb, delay and modulation effects, crafted by our renowned in-house effects team, that can be dialled in quickly to bring a performance to life.
USB AUDIO FLEXIBILITY
All ZED Mid models feature a 2-channel interface with flexible send options including Main Mix L+R pre or post-fader, Auxes 1-2 or Auxes 3-4. The USB return comes back in on a stereo channel for playback and monitoring. 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 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! CD quality audio to and from your PC or Mac. Switches and connection through jack socket terminals provide different send/return configurations:
SEND OPTIONS
1) Main Mix Left + Right (Post-fade)
2) Main Mix Left + Right (Pre-Fade)
3) Auxes 1-2
4) Auxes 3-4
RETURN OPTIONS
1) To Stereo 3 channel
MUSIQ
Our analogue engineers designed the MusiQ EQ especially for ZED mixers, carefully optimising the curves and target frequencies to deliver a simple to use, musical EQ that works equally well on stage or in the studio. Each ZED Mid mixer features a responsive 3-band, swept mid frequency EQ design with optimised slope (or Q factor) for equalising individual instruments. The ZED-12FX features a responsive 3-band, swept mid frequency EQ design which utilises MusiQ – with optimised slope (or Q factor) for equalising individual instruments.
ZED-FX
ZED-12FX has an essential selection of 16 time-delay effects, designed 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. Our DSP engineers worked hard, crafting and refining beautiful reverb algorithms to enhance every performance. These effects are available nowhere else at this price point – this quality and integration is only available from the ZED-FX. ZED effects are easily controlled using 3 buttons with 9 display LEDs. For example, the ideal delay time can be quickly tapped-in, or the perfect amount of reverb on the lead vocal can be dialled-in. There is one-stop navigation and editing – in fact, it’s just as easy as using effects pedals. To alter effects parameters, the TAP button is held down and the up/down buttons pressed to adjust the specific parameter for that effect, for example, the decay length on PLATE, or the depth on CHORUS.
DUOPRE
Based on the proven pre-amps from the hugely successful PA series, ZED-12FX has DuoPre 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 and also matching to a
higher input impedance.
