Andy Rigby-Jones’ new MasterSounds flagship 4V is a 4-channel DJ mixers aimed at clubs and DJs who desire “no compromise” audio fidelity. Jones, the genius behind the revered Allen & Heath Xone mixers, builds each of the MasterSounds audio products by hand.
Available in both rotary and linear fader options, the Radius 4V and Linear 4V contain 4 fully-featured channel strips with Aux send (switchable pre or post fader), input level trim, illuminated input select switch, a super smooth 3 band asymmetric equalizer, large illuminated Cue switch, high quality faders (TKD for the Linear 4V and Alps for the Radius 4V) and 10-point LED VU meter.
To the right of the channel strip features a 3-band Master EQ/Isolator, Master and Booth level controls, headphone monitor with split and Cue/add mix control. Below the master section is a high-quality Penny & Giles crossfader, with contour control to adjust the curve from smooth mix to fast cut.
Two 36mm illuminated analog VU meters (LOVE! —Ed.) provide accurate signal level monitoring of the mix buss, these automatically switch to monitoring the Cue level when a channel Cue is activated. If the signal level is excessive, the VU meter illumination will change from warm white to bright red.
At the heart of the 4V are four matched dual triode valves (tubes) which form part of the input buffer stage to the VCAs. The valve’s high input impedance minimizes loading on the preceding stages but provides low output impedance to drive the VCAs, whilst the valve’s natural compression smooth and warm harsh transients. Careful circuit design around the valve minimises noise and distortion. A new split composite/passive RIAA stage featuring Vishay 2% Polypropylene capacitors, close tolerance thin film resistors and JFET pre-amplifiers provide outstanding fidelity from the turntable inputs. All circuit coupling is through bypassed Panasonic electrolytics to preserve this fidelity throughout the entire signal chain. The icing on the cake is a pair of MUSES01 operational amplifiers, providing world class summing for the fully balanced main mix buss.
