Pure DMX-50 Review: Winner DAB Microsystem (9/10)

Pure Digital DMX-50 DAB MicrosystemDespite our catastrophic experiences with the Onkyo DAB CD unit, we’d developed a taste for DAB radio/CD combos so were right on Pure Digital’s case when they announced their new DAB/FM/CD/MP3 micro system, the DMX-50.

Perhaps better known for their distinctive portable sets, Pure are a world-leading, UK-based DAB radio retailer, with a reputation for innovation.

Rolled out just in time for Christmas, the £230 ($395, €336) DMX-50 is an attractive 40W RMS micro-sized system, cunningly disguised to look like three hi-fi separates.

Finished in a pleasant grey metallic finish, the unit is dominated by a large, five-line LCD screen which provides DAB/FM radio station information, scrolling DAB digital text, CD/MP3 track listings and access to a variety of user-selectable options.

Setting up the DMX-50 was an absolute breeze – no sooner had we got the thing plugged in than it was busying itself automatically locating and storing over 50 DAB stations within range. Nice.

Locating FM stations was equally swift and painless, with the large, intuitive interface making it a breeze to find, sort and order presets – kudos to Pure for simplifying a process that can sometimes turn grown men into fist-shaking balls of frustration.

Playing CDs was straightforward enough too, although the CD tray was a little too flimsy for our liking.

We especially liked the fact that it displayed both CD and MP3 track and artist information onscreen, making it easy to find tracks.

Pure Digital DMX-50 DAB MicrosystemA unique feature to Pure is the ReVu function, which lets you pause and ‘rewind’ live DAB digital radio, courtesy of a constantly updating 20 minute buffer.

This means that it’s possible to rewind back to the start of a show you may have missed the beginning of, or pause the radio to take a phone call.

DAB digital transmissions can be recorded (or played back) on the built in SD card slot, and a USB port lets you play back and transfer recorded files to your PC.

The USB connection can also be used to download software upgrades for the DMX-50.

Further connections come in the form of a pair of spring loaded speaker clips, two aux inputs (for plugging in an MP3 player, for example), an optical out and a Line/Sub Out for hooking the unit up to an external amplifier or connecting a sub-woofer.

Quick to set up and a pleasure to use, Pure’s straightforward interface, massive LCD and impressive feature set make this a great player for music fans who don’t fancy wading through hefty manuals before they can start listening to tunes.

At this price level we weren’t looking for high-end hi-fi quality, but the DMX-50 gave a good account for itself and was a pleasure to listen to.

The bass output perhaps wouldn’t excite dub aficionados, but when cranked up, the sound was beefy enough to encourage a bit of air guitar work around the office.

Throw in CD/MP3 text, a SD slot and the unique ReVu feature and you’ve got the best all-round DAB/CD player we’ve come across so far.
