We hand build all our DJ mixers, FX units & LinearPOWER accessories to order, via analogue legend Andy Rigby-Jones & his small team of ultra passionate audio professionals in approximately 7 days.
The new generation Radius 2 and 4 offers clean, open, and dynamic sonic quality on both LINE and RIAA inputs, as well as improved usability. Both mixers feature easy-reading analogue VU meters, a responsive Master EQ/Isolator, a smooth natural sounding hi-pass filter on each channel, and an AUX send/Return system with insert button for easy integration of external effects, including MasterSounds own FX unit. Radius 4 also includes 2 mic inputs, selectable via the rear panel.
“The redesign challenge meant going back to the drawing board to see where we could simplify the circuitry without impairing performance. For instance, the Split Composite Passive RIAA stage remains identical to the previous generation but we have simplified the post-fader circuitry. The biggest change was to the internal construction and PCB board shapes, where we have optimised them for maximum efficiency through our in-house fabrication plant which has made them a lot easier to manufacture. What we haven’t compromised on is the quality of the components used, and the third-generation mixers all feature Alps pots/switches, close tolerance resistors/capacitors, and Panasonic electrolytics. I am very happy with the result of the engineering changes, and these compact mixers offer exceptional value for money,” explains Union Audio’s Andy Rigby-Jones.
“The Radius 2 and 4 hold a special place in my heart, it’s the mixer Andy and I began our audio journey with, and one that gives the user a really unique way of blending records. Both Radius 2 and 4 are desktop products, with a small footprint, which makes them perfect for home, touring, and club use, or all three! It was the right time to re-engineer Radius, giving more DJs the opportunity to experience our wonderful product, at a price unseen given each mixer's quality of build and fidelity of sound,” concludes MasterSounds founder, Ryan Shaw.
