MasterSounds & Union Audio unveil the new MK2

MasterSounds and Union Audio continue their award-winning partnership with the creation of the new MK2 version of their flagship Valve range of hand-made esoteric DJ Mixers. Released today and marking 15 Years of MasterSounds, the Valve MK2 range is now available to purchase.

Valve MK2 encompasses the true spirit of its predecessor, with its esoteric principles of sound and simplicity, and now includes added playability with a VariableQ high pass filter per channel, a re-designed 3-band EQ and RIAA Input stage, plus Innofader as standard.

Designed by Union Audio’s founder Andy Rigby Jones who has been at the forefront of analogue DJ mixer design for over 25 years and MasterSounds’ founder Ryan Shaw, whose history in DJ and audio has pioneered an incredible and revered line of high-fidelity audio products from DJ mixers, FX units, turntable weights and more, each Valve MK2 unit is hand-crafted in small numbers by Union Audio in Cornwall, England.

“We are so very proud of Valve, and the addition of the new features in our MK2 model elevates the DJ mixer’s playability for discerning DJs, from club and bar owners to home DJ’s, Valves club standard feature set and beautiful open, dynamic & transparent sound is a real gem to experience”
– Ryan Shaw (MasterSounds, Founder, Director)
“It’s hard to believe that five years have passed since we launched the original FourValve, but it’s a fitting anniversary on which to launch the new MK2! The addition of VariableQ high-pass filters and an all-new EQ adds another level of playability and audio manipulation. The new MK2 comes fitted with an Innofader as standard and a revised RIAA preamplifier, which along with all the other changes makes this a significant update on the previous model”
 Andy Rigby Jones (Union Audio, Founder. MasterSounds MK2 Valve Series, Product Designer)
MK2 Valve is available in both 2 and 4-channel options, in MasterSounds classic black and silver finishes.
Priced at £1895 for the Radius Two Valve and £2695 for the Four Valve model (minus VAT for buyers outside the UK).
