Allen & Heath Xone:43C Mixer Review

Phil Morse
Last updated 8 January, 2019


The Lowdown

A full-featured four channel mixer compatible with Serato DJ and can be upgraded to support Serato DVS. A great “basic” pro mixer that’d be more than happy at the heart of an ambitious home DJ system for Serato DJ, especially for DJs wanting to use CD or vinyl DVS, and wanting to add something like a Xone:K1 for more controllerist-style features. One to grow with you and your DJing.

First Impressions / Setting up

The modern-looking, quite funky and cheerful top panel of the Xone:43C. Note that the “fifth” input (mic/aux) and the headphones sockets are all on the top panel; there’s nothing on the front at all except a logo.

Allen & Heath is a quality brand, and its gear always looks and feels the part. From the off, this mixer doesn’t disappoint. In the company’s new, updated livery, the Xone:43C looks rounded and funky, while still meaning business. It’s aluminium, making it a sturdy and relatively lightweight design, and the knobs are mounted metal-to-metal on the chassis. The box has a couple of leads and some spare knobs and fader caps in with the bagged quickstart guide, which is a nice touch.

Setting up involves installing Serato DJ, installing the Allen & Heath Xone:43C driver from within Serato DJ software itself, and finally if you want to use DVS (I think most users will), ensuring you have that version: Buying the Club Kit version outright is £110, or upgrading to Club Kit is you already own Serato DJ is £65. (Note that once you have Club Kit, you can use Serato DJ with any compatible digital mixer, not just this one.)

Once you’ve calibrated your digital vinyl and followed the audio routing wizard, you’re ready to go.

In Use

The mixer has four switchable analogue/digital channels, plus an extra mic/aux channel, that has a rotary gain and two-band EQ, effectively making it a fifth channel. Paired with Serato DJ software, it gives you control over all four Serato decks. The four main channels are switchable phono/line/USB, and each has its own VU meter in addition to the master VU.

The channels all have a big fat “X-FX” knobs that I suspect many DJs will assume at first glance is a filter per channel, but actually, these knobs are individual sends to any external FX unit you may have plugged in. (In the video, you’ll see we tested it with a Pioneer RMX-500.) There aren’t individual hardware filters at all, but there is a single Allen & Heath hardware filter, and you can switch each channel on or off in order to send its output through that filter. The filter sounds great, with “mild to wild” resonance and a choice of high-pass, low-pass or (unusually) mid-pass options, but analogue DJs using the mixer may find a single filter restrictive.

The back of the unit. Note a full complement of four phono inputs, and the X-Link network socket for adding in Allen & Heath extra hardware, meaning only one USB back to the computer.

The feature set past everything mentioned so far covers all the basics a pro would need: As far as inputs and outputs go, all four main channels can be record decks or line as well as digital, there’s that fifth mic/aux channel, and outputs are balanced XLR/unbalanced RCA master, plus unbalanced RCA booth; many DJs will love the fact that the headphones section includes a split cue; likewise, scratch DJs will appreciate the crossfader three-way adjust, although the crossfader itself is too stiff for advanced scratching (it’s Mini Innofader replaceable, though).

Unlike Allen & Heath’s more expensive mixers such as the Xone:DB2 and Xone:DB4 there are no onboard FX past the single filter; this is very much a mixer designed for expansion when the DJ is ready to spend more money, as stated earlier, so there’s the extensive FX send/return feature for adding an external FX unit if desired.

However, as mentioned in the intro, the X-Link network socket offers a really simple way to add a controller for software control; the Xone:K1 is Serato DJ-supported out of the box and will give you loops, cues, sync, library controls, and control over both software FX and filters, so you get your per-channel filters that way. For DVS users or even users wanting a stripped down modular set-up, adding a controller like the K1 would be a great move a great move.

As far as sound quality and the “in use” feel of the mixer go, the best way to describe DJing with it is that it doesn’t feel like you’re using a digital DJ set-up at all: It really does feel like DJing done “the old way”, as everything’s that much bigger and more spaced out, and to me at least, having comprehensive and trustworthy metering helped to add that “manual” feel back to things. The sound overall was fantastic, and the hardware filter sounded great… plus as we hooked it up to an external FX unit too, we found it hard to pull ourselves away to actually film and write the review!


This mixer is a statement of intent by any DJ buying it. It says: I’m going to build a DJ system at home that looks, feels and acts similar to the gear I find when I play in clubs. It says: For me, a simple controller isn’t going to be enough. Hooked up with a pair of (any type of) DJ CD player, or a pair of record decks, the Xone:43C gives you an easy to set up, professional feeling basic DJ system but which you can, from there, take in any number of directions as your DJing career develops.

Want hardware control over loops, filters, FX, library selection etc? Add the Xone:K1 and with a single cable, it’s all there. Want to add in an external FX unit, having fallen in love with one in a club you DJed at? The send/returns you need are present and correct, and the mixer has a really versatile X-FX system to let you get the most from such a unit. Want to simply DJ from CDs or records? Depending on the “deck flavour” you chose for your DVS control, at the flick of a switch, you can – even in the same DJ set. Want to DJ with a vocalist, or another DJ with their own controller? You’ve got a decently featured channel to plug them in, too.

It’s an attractive and modern-feeling device, in keeping with the “new” Allen & Heath look, as sported by the Xone:23, Xone:23C and Xone:43.

Indeed, while it’s sold and badged for Serato DJ, there’s nothing stopping you using it with any DJ software, and it’d work just as well with Mixvibes or Virtual DJ DVS, for instance, right out of the box in the same way that it works with Serato DJ Club Kit. So again, another layer of flexibility.

At its list price of £799, it’s a fair and solid piece of kit to build a system around, and while its feature set is relatively basic compared to higher end (and more expensive) mixers, it has few limitations for growing with you into the future. Couple that with great sound quality, and the clever X-Link idea to make adding extra components easy (and remember, nowadays with Serato you can map supported devices yourself, so they’d be nothing stopping you daisy-chaining K1s, for instance, to make a controllerist’s dream set-up…), and you have a very desirable mixer for the serious hobbyist or ambitious prosumer DJ.
