Go to power and versatility

I own 2 of these. One stays in my studio, has been there a decade. It works every day, with plenty of gain to push a quiet acoustic guitar when that happens. It provides complete connectivity for my Pro Tools rig, 16 channels of great sound, reliable. I also use one live, with my band and rentals. That mixer sees a lot more abuse, riding around in a case and trailer, lugged up stairs, pounded around, bumpy carts and roads. It never blinks, it only works it's butt off. I've never used all 6 aux mixes, but I use the aux (monitors), mains (FOH), EQ and gain just like I do in the studio. This mixer is capable of solving both problems, and I don't even give it a second thought. In a world where folks are buying mixers with digital controls on their IPAD, I could still sell these Allen & Heath mixwizards to anyone with a brain. It's just gonna take care of you.

Great Board and Sound

Great board. Using it as our main sound board with a Sound Craft for Sub Mix of our Drums. Monitoring for the band is now super easy.

Allen & Heath WZ4:16:2

If you have ever experienced latency issues when recording in your studio, this is the best front end your system can possibly have. The six aux sends permit individual monitor mixes that musicians/engineer(s) can use to monitor playback in real time, The direct outs on each of the channels are great for recording in the studio, or live. I'm surprised more manufacturers don't have something like this.

Mixwizard magic

We purchased a Mixwizard 16:2 for our FOH running into powered speakers - construction is solid, all knobs and switches feel pro and the long channel sliders feel great and hold a wealth of headroom set in conjunction with the highly adaptable Gain and Pad level controls. 4-way channel EQ with mid-high and mid-lows sweepable is unbeatable, onboard effects are really good with enough parameters to tweak and the processor runs as a dual/stereo one so you have 2 effects available per channel. Love the input connections going horizontally into the back panel - keeps the mixer desk so much cleaner - and the under-mixer storage also helps heaps with keeping your work area tidy during the show. Enough AUX sends to sink a ship, direct outs an amazing "extra" feature and master L and R Main Mix Insert means we can add a FOH stereo EQ rack to tune to a room. Overall headroom and noise floors are amazingly clean, board layout is very intuitive given how many channels and features are squeezed onto a rack width panel.

This board has been upgraded substantially since the version I had for over 3 years. They came out with Mix Wiz 3 and now 4. I was ready see what was out there and was told Soundcraft had really improved their pre - amps and quality. I had a S.C. for 8 years and liked it so i bought what is supposed to be their comparable board to The A&H Mix Wix 4 { The S.C FX 16:2 } It does NOT compare !. Maybe it does to my 3 year old A&H board which is very good, but I wanted better and traded it in for the A&H Mix Wiz 4. All I can say is the pre-amps have DEFINITELY been redesigned and upgraded. They are very punchy, clean with much more headroom, which in a rock band is really needed ! The board is built sturdy and has a better digital effects section and an EQ in/ out switch which is very helpful. A+ to A&H for staying on top of their game !

Sweetwater Advice

Tyler Berggren

I use my MixWizard as the front end of my recording rig. Using the channel direct outs set to post fader gives me full control of my levels before hitting my A/D converters. The preamps have gobs of headroom and plenty of gain on tap, the EQ section is great for boosting what you like about a sound and cutting out what you don't, and the built in effects can hang with any stock DAW plugins easily.

Evan Mehre

The WZ4:16:2 is not just a great board at an approachable price point, it’s THE STANDARD for analog, rack-mounted consoles. It’s built like a tank, but easily serviceable, and with its quality preamps and built-in effects, it’s a gem. I’ve mixed on mine for YEARS, and I’d happily use one at any show with an appropriate input list!
