MasterSounds unveils 3rd gen Radius 2 & Radius 4 DJ mixer

MasterSounds has unveiled the third generation of Radius 2 and Radius 4 DJ mixers that are now more efficient than ever and feature more simplified post-fader circuitry than the predecessor. Both of the DJ mixers offer a high dynamic range on Line and RIAA inputs as well. On the top panel of the MasterSounds Radius 2 and Radius 4, you will find two analog VU meters, a Master EQ/Isolator, a HPF for each channel, & more controls.

While both of the products share similar features, they also differ from each other in various aspects. The biggest difference between the MasterSounds Radius 2 and Radius 4 is the number of channels each DJ mixer can offer. Radius 2 offers two channel-inputs with stereo RCA (PHONO & LINE) ports for each individual channel. Whereas the Radius 4 comes with four channel-inputs supporting the same PHONO & LINE configuration for each individual channel.

Unlike Radius 2, the Radius 4 DJ mixer equips 2 mic inputs. You can engage or disable either of the mic input via the “MIC ON” switch on the rear panel.

Apart from connectivity, these DJ mixers offer a slight difference in terms of dynamic range and distortion.

Statement from Union Audio’s Andy Rigby-Jones

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 optimized 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.

Statement from MasterSounds Founder Ryan Shaw

“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.
