Radius MK2, it's Radius on another level.
Built for Discerning DJs.
“Radius MK2 stands on the shoulders of our previous Radius model, adding a host of new features and keeping our original footprint. We listened to the comments of our MasterSounds community and added upgrades that felt natural to grace the MK2 Radius model for 2023."
- MasterSounds Founder, Ryan Shaw
“It’s incredible to think that the original Radius design is now in its eighth year. It’s a product that set the benchmark in terms of performance and affordability, so coming up with a successor has not been easy. The design brief was simple, to retain the character of the original product, yet offer a more contemporary feature set without compromising performance. The real challenge then was to achieve all this without adding significantly to the cost, and I'm pleased to say that it’s a challenge we have been happy to meet”.
- Union Audio Founder, Andy Rigby-Jones
What's New for Radius MK2.
4/3 BAND ISOLATOR - Radius MK2 features our 4/3 band isolator, for creative isolation and shaping of sound. Ultra versatile with 4 bands of isolation, switchable to 3 bands at the touch of a button, with full cut to +7dB of boost per band with crossover points from 110Hz to 3000Hz.
ISOLATOR FREQUENCY BANDS
4 Band Mode:
Sub: 110Hz
Low: 210Hz
Mid: 1500Hz
High: 3000Hz
3 Band Mode:
Low: 650Hz
Mid: 1500Hz
High: 3000Hz
VariableQ HPF - The new Variable-Q filter provides a natural roll-off at low frequencies, lending perfectly to mixing with filters alone, but as the HPF knob is rotated the Q automatically rises to provide that classic analogue swept filter sound, with a high-pass filter frequency range of 15Hz –1.5kHz.
ADD MIX - Radius MK2 now shares the ADD MIX knob found on our flagship Valve series, and enables control of the amount of stereo mix sent to your headphones. When the knob is rotated full anti-clockwise only the cued track can be heard. Turning the knob clockwise increases the amount of stereo house mix that can be heard in the headphones.
RETURN - We have added a separate return knob for increased control of the AUX return channels when using aftermarket FX units.
PHONES - Radius MK2 now offers the option of a 1/4” or mini jack headphone input.
REFINED FIDELITY - Redesigned internal circuitry offers superb fidelity with MasterSounds open, natural, and dynamic sound stage, with high headroom & low distortion.
