NEXT-GENERATION SOUND QUALITY GETS PC-LIKE POWER

-

Today’s music-lover has never had it so good: the vinyl revival, internet radio, plus the growing popularity of music streaming, like Spotify, Amazon Music and Google Play Music services. We’re even able to enjoy recording studio sound quality (better than CD) with the right equipment.

Most of today’s music is digital and there’s one crucial piece of electronic­s that determines how good that music can ultimately sound: a DAC (digital to analogue convertor). The chances are, you’ve already used a DAC in the past 24 hours: that smartphone call, TV news catch-up or internet surf; DACs are essential circuit board devices embedded into everyday gadgets converting digital signals into analogue ones, so you can hear them.

Most are tiny chips, costing no more than a few pounds, machine-soldered into circuit boards, like the one in your phone. At the opposite end of the scale, however, are external, matchbox-sized DACs that plug in to smartphone­s, tablets, laptops, computers, TVs, hi-fis and more, to upgrade (and transform) sound quality. The difference can be likened to HD video: suddenly music has more clarity, more resolution and is more “real”.

The world leader in DAC technology is British. Kent-based Chord Electronic­s has been making award-winning DACs using proprietar­y technology since 1996. Having discovered basic chip-DACs sounded awful, it applied computerli­ke levels of processing power to the task, employing highly advanced programmab­le devices (FPGAs), customcode­d by its expert audio designers.

Chord Electronic­s’ DACs, from the smartphone-enabling rechargeab­le Mojo to the Hugo 2 (pictured) are hand-made in the UK with British design, expertise and software. The company has the most advanced digital technology the world has to offer and has accumulate­d more major awards than anyone else. To experience your favourite music in HD, search ‘Chord Electronic­s Mojo’ to begin your journey of discovery.
