Built around the same mastering-grade circuitry found in our standalone units, the ISO420 represents the ultimate expression of analogue mixer design, approaching the limits of what is theoretically achievable with just 0.00033% THD+Noise.
Precision components and low noise design enable ISO420’s phono preamps to exceed the measured performance of many single channel preamps costing more than the entire mixer, with RIAA conformity within +/-0.2dB @ 20Hz-20KHz.
– Built around the same mastering-grade analogue circuitry used in our rack-mount units
– Audio measurement figures which exceed any analogue mixer we have ever tested
– Powered from a compact version of our LRPS power supply
– Now ships with front headphone socket as well as rear
– Dimensions 305mm x 305mm x 120mm
0.00033% THD+Noise from input to output (2V RMS, Unity Gain @ 1KHz, RCA Out)
0.00060% THD+Noise from input to output (2V RMS, Unity Gain @ 1KHz, XLR Out)
120dB Channel fader cut @ 1KHz on all channels (+/-2dB)
>95dB Isolator fader cut @ 1KHz on either isolator *
>90dB left-right crosstalk isolation @ 1KHz
<90dB Headphone Residual Trace @ 1VRMS into 30R
Better than +/- 0.2dB Frequency Response from 20 Hz to 20 KHz from any input to
output
Inert gas-sealed relay isolator routing (unlike other mixers, where the isolator is
permanently in circuit, the ISO420 enables you to switch it in and out for comparison,
proving how transparent it is)
Double-skinned hybrid stainless steel / alloy construction
Proprietary solid alloy billet-machined knobs with custom-moulded silicone rubber grips
Better than 0.3dB Channel Matching using specially selected pots
Dual-Mono Phono Preamps on Channels 1-3
Lundahl Output Transformers (manufactured in Sweden – widely regarded as the world’s
finest transformer manufacturer), driven via distortion-cancelling circuitry
