Allen & Heath sound with USB!

Allen & Heath's ZED-428 gives you all the essentials you need for flexible live mixing: 24 channels with smooth, long-throw faders, 4-band EQ with swept mids, six aux sends, and four sub groups. You also get a direct output on every channel and master level controls on all outputs. It's an incredible amount of flexibility, at a great value, but Allen & Heath added another dimension of functionality to the ZED-428: USB connectivity! Now you can get clean, clear audio straight into and out of your computer with the ZED-428.

Allen & Heath ZED-428 at a Glance:
  • Legacy
  • Best of previous designs
  • USB

Legacy
The ZED-428 has a fantastic pedigree which comes from nearly 40 years of making mixing desks for the professional sound community. The audio circuitry is based on years of continual development and refinement and the performance of all the elements within the mixer has been perfected to ensure the very best sound quality possible.

Best of previous designs
The ZED 4-Bus series takes inspiration from different product lines within the A&H range, combining them with fresh new ideas to give stunning results in a neat and easy to use package.
The padless DuoPre mic/line pre-amplifier is the new design first implemented on the ZED-14 and delivers a high-headroom, low-noise signal. The 4-band, 2 sweep EQ, along with the low noise summing amps, is borrowed from the acclaimed GL2400, while the bus architecture is a simplified, but equally comprehensive, version of that employed in the successful GL series.
USB
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.

Allen & Heath ZED4-28 Features:
  • 24 Channel
  • 4-band EQ with 2 swept mids and in/out switch
  • 6 auxiliary sends (2 pre, 2 post, 2 pre/post)
  • 4 sub groups fed from each channel
  • L, R and M main mix outputs
  • Individual channel 48V phantom power
  • Direct output on every mono channel
  • 2 dual stereo inputs with 4-band EQ
  • Peak and signal indication on every channel
  • 2 matrix sections available; can send output to USB
  • Configurable USB stereo audio in/out
  • Master level controls on all outputs
  • Easy to use layout - all connections and controls on top surface
Allen & Heath's ZED-428 brings the best of the past into the present!

What is Demo Gear?

At Sweetwater, we're so picky that what we call a "demo" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

What demo means to us is that we've had it out of the box, or maybe it was in a customer's hands for a few days and isn't "factory fresh" as a result. Every demo item we sell has Sweetwater's 2-year Total Confidence Coverage™ warranty, and has been tested and verified up to "new" specs by our factory-authorized technicians to make sure it's in perfect working order before we ship it to you.

When you buy a Demo item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Rated 5/5

Best so far

This is the 9th mixer I have bought in the last 11 years for a school system. I have used Peavey, Mackie, Yamaha and some others during my tenure setting up and designing systems for numerous schools. This mixer is the most musical, thought out, responsive I have yet to use. Post and Pre fade monitors for all channels plus USB. We do a lot of theatrical productions, and this has been the best fit so far. Highly recommend it. All of the praise should go to my sweetwater rep Luke, he has yet to lead me astray.
Rated 5/5

Just as advertised

Want a great mixer? This is it. With super quiet preamps, plenty of headroom, great EQ section, six aux sends, silky smooth long throw
faders and built like a tank. This true 24 channel mixer is a winner.
I use the USB to record band rehearsals for instant playback reference and for "live" demos and song ideas. The recordings are crystal clear.
You will have to use the channel strips to return your aux/efx sends since it has no aux returns or inserts, but that's how the big shows do it anyway.
So, for a great price and the Allen & Heath name, you can't go wrong with this mixer.

King of the 24 Channel Analog Consoles

This board is the greatest 24 channel mixer ever made for less the 2000 dollars.

I have been the chief sound engineer at my high school for the past 3 years, and have used this board almost the entire time. In my time it has been through 3 musicals, 4 cabaret shows, 8 talent shows, 13 concerts, and preformed absolutely flawlessly.

This board was bought used by the school in 2002, and I have been told that it was manufactured in 1996, and used as a rental up until we bought it. That means that it managed to survive 6 years in a PA rental house, and 8 years of student sound engineers up until I arrived. It is still as good as new.

Unfortunately, earlier this year, someone opened the flight case locks and vandalized the board while I had it set up for a show. I sent it off for repairs, and had to use a Soundcraft LX7ii while I was waiting for it to come back.

Following that experience, I swear I will never use another brand of large format analog mixer ever again. Allen and Heath is the best.

Sounds great and built like a tank

Based on great reviews about this board, I purchased a ZED428 to handle studio recording and live sound situations for me. The other reviews were right, and I'm adding mine to the pile...this is a great piece of gear! Fit and finish are excellent. My favorite features are: 100mm faders, signal LED's on each channel, direct outs on each channel, switchable phantom power on each channel, bypassable 4-way eq's, and the small level meters on the subs and mains. Between the two matrix sections, 4 subs and 6 aux channels, there are a lot of routing capability with this desk. Highly recommended!

Nice sound board

I have had this mixer for about a year and really like it. Lots of in's and out's. Nice pre's but not the best. It's not a 5000 dollar mixer but works well for me. Top loading makes it easy for recording. Has most of the bells and whistles but no on board effects. If the pre's were just a little warmer and on board effects were added it would surely be one of the very best. Over all performance is great. Totally happy with this mixer. I called Allen And Heath with a question and they responded to my question FAST. They emailed me with a answer in just a few minutes.
