Radius 4 Black
*Current Radius 4 build time is 5 days*.
In November 2016 MasterSounds launched the Radius 2 analogue rotary DJ mixer in collaboration with Union Audio to a rapture of global praise. Fast forward seven months and the Radius 4 is now here, a product ready to build upon the Radius 2’s worldwide success.
The Radius 4 has been designed by MasterSounds and Union Audio and developed by Union Audio at their Cornwall based workshops. Andy Rigby-Jones, former head of design for the world-renowned Allen & Heath Xone DJ mixer range, has personally designed, built and tested the analogue electronics, whilst MasterSounds founder Ryan Shaw not only worked on the mixers feature set, but his family owned metalworking factory manufacture the mixers outer casing.
Each mixer is lovingly hand-built, tested and shipped direct from Union Audio, ensuring the ultimate in quality, reliability and performance.
Andy says; “Just like the Radius 2, the Radius 4’s signal path features pure high-end analogue topology for minimal distortion, low noise floor and high headroom, aided by only using components of the highest quality”.
With more than twenty years experience of DJing, as well as a background in design and manufacturing, MasterSounds founder Ryan Shaw says, “The Radius 4 is a fabulous addition to the MasterSounds range and is a response to customers who love the Radius 2’s unique design, but require 4 channels when DJing”.
The Radius 4 offers a fantastic clean, open and dynamic sound on both LINE and RIAA inputs across all 4 channels, as well as great usability. The mixer features easy-reading back lit VU Meters, a responsive Master EQ/Isolator, a smooth natural sounding Hi-Pass Filter, and Aux Send on each channel.
A new and unique feature is the ability to reconfigure the Aux Return Jacks as a Mix Buss Insert, giving the user unparalleled flexibility for FX integration, simply at the press of a button.
And last but not least, the addition of two Mic inputs gives the Radius 4 the club standard specification seal of approval.
Size L 350mm X D 190mm X H 80mm.
On the Premium option we use the finest sounding esoteric operational amplifiers on the market today which aide to the already superb transparency of the standard unit.
