The Valve MK2 is available now in two and four-channel options with each unit hand-crafted in Cornwall, England.

To celebrate its 15th birthday, English Hi-Fi firm MasterSounds have unveiled a brand new MK2 version of their highly praised Valve DJ mixer in partnership with Union Audio. The Valve MK2 stays true to the original by continuing to prioritize sound and simplicity over all else but goes further by adding a VariableQ high pass filter per channel, a re-designed 3-band EQ and RIAA Input stage, plus Innofader as standard.

The mixer was designed by Union Audio founder Andy Rigby, a leader in analogue DJ mixer design for over 25 years, and MasterSounds’ founder Ryan Shaw, creator of revered high-fidelity audio products including DJ mixers, FX units, turntable weights and more.

Speaking on the release Shaw said, “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 DJs. Valve’s club-standard feature set and beautiful open, dynamic & transparent sound is a real gem to experience.”

Rigby adds: “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 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.”
