The family of the noble Rotary Boutique Mixers gets further growth: MasterSounds Radius 4 is the four-channel version of the two-channel DJ Mixer Radius 2, presented in November 2016, which received much praise. Like the small vanguard, the big brother is available in black and silver finish, has an analogue signal path for minimal distortion, low noise and high headroom, and is completely hand-made in England.
