The Lowdown

The Reloop Flux is an excellent modern addition to the DJ gear market, filling a real need for a Serato (and wider) DVS audio interface, a gap left by other companies exiting this niche. It turns any mixer into a DVS mixer with modern USB-C sockets including USB-C PD, and is a 2-port USB-A hub too for good measure. Plus, it unlocks Serato DJ Pro and Serato DVS. Top marks!

First Impressions / Setting up

The Reloop Flux is a well-made, all-metal DVS audio interface for Serato. It has recessed edges to protect the buttons, switches and sockets, and two flush buttons on the top for audio through.

It’s pleasingly weighty, and comes with a pair of RCA cables for plugging from the unit into your mixer, and also with a choice of USB cables for plugging into a computer from its USB-C socket.

The Flux comes with everything you’d expect on modern gear, and fills a real gap in the market.

It’s a six-in, six-out audio interface, meaning you can use it with up to three turntables/CDJs. The third input can feed through Serato’s sampler channels. There are discrete switches for switching from line to phono. There is an earth pin for earthing your turntables.

The unit is bus powered, but you can use USB-C PD power too, for instance, if you want to power it without a computer in order to use the through function for just DJing with vinyl, or if you want to power your computer from it. All of this makes it a really thoughtfully designed device for DJ use.

In Use

Because you can use this bus-powered or by using a power supply in use, it’s extremely convenient, because in a permanent set-up you could have everything powered through this, including your computer. Conversely, in a club – there’s no need to fuss around trying to find a power supply – you can just power from your laptop.

Also the fact that you’ve got the hub means that it’s just very convenient to add a computer, controller decks/accessories etc and leave everything set up all the time, neatly.

Setting up is a breeze, so DJs can easily add this to their home studio or bring along to a gig.

The LEDs on the top are super-cool because they show you how everything is configured at a glance, and so this really is a set-and-forget device.

Because it’s 24-bit 96 kHz, it sounds great and it’s also ultra low latency, so basically from a performance point of view, it’s as good as any DVS interface that has preceded it – but it’s brought thoroughly up-to-date with the new USB-C and power-over-USB additions.

Basically, you’re going to love using this if a USB DVS audio interface is something you’ve been yearning for.


Well done, Reloop! With Rane and Denon interfaces now hard or impossible to find (or hopelessly outdated), there was a gap for this, and Reloop has always been pretty good at spotting this kind of niche.

The combination of unlocking Serato, high-quality audio, and a USB hub including power over USB simply means this is a future-proofed audio interface that – for the DJ who still requires this kind of device – is going to be a godsend.

Reloop has a real knack for spotting much needed, niche items, and this one’s a belter.

If you are wanting to use Serato or indeed any other software that works with DVS with an old mixer that you love and don’t want to replace, it’s certainly going to be for you – but also if you have a boutique mixer (and there are plenty of those out there at the moment) that doesn’t have an audio interface built-in, again, it’s the perfect way to add the extra functionality.

It’s not particularly cheap, but you’re getting a well-made audio interface for your money, and you’re also getting that software licence thrown in as well. Unlike the old Traktor Audio 10 (for instance) it is not a four-channel DVS device – most DJs will use this with two decks – but I think for nearly everyone that will be fine. Remember you’ll need to provide your own control vinyl, as none is included.

Top marks to Reloop for this!
