With approval from house heavyweights, Bicep, and supreme selector, Giles Peterson, boutique UK mixer brand, MasterSounds is renowned for its high-quality rotary mixers. Radius 2 and Radius 4 DJ mixers became favourites in the deck-spinning community after their launch in 2016, and are making a return with some technological enhancements and a new price tag.

“Four years on, and the brand has seen remarkable growth but the higher production costs of a premium rotary mixer rule them out for DJs on a tighter budget,” explains MasterSounds’ founder, Ryan Shaw. “Designer, Andy Rigby-Jones, and I decided to do something about it, by redesigning the compact Radius 2 and Radius 4 to make them more affordable but without compromising any of the features, the feel, or the audio fidelity of the original model.”

The new Radius 2 and Radius 4 feature improved sonic quality on both Line and RIAA inputs, sounding more “clean, open and dynamic, as well as improved usability” according to MasterSounds. They feature easy-reading analogue VU meters, with a responsive Master EQ/Isolater with smooth high-pass filters on each channel. An AUX send/return system will please experimental DJs looking to include external effects, including MasterSounds own FX unit. Radius 4 also includes 2 mic inputs, selectable via the rear panel.

MasterSounds collaborates with Union Audio on these mixers, an engineering company run by Andy Rigby-Jones, who was head designer of the Allen & Heath Xone range. Speaking on the new Radius models, Rigby-Jones says“ “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”, Andy Rigby-Jones continues. “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,”

The two new rotary mixers are available now, with Radius 2 priced at £799 and Radius 4 priced at £1089. Find out more at
