Focusrite ISA430-MKII overview

  • 1Description

The ISA 430 MKII is a single input analog channel strip that brings together all of Focusrite's classic processor designs in one comprehensive production tool. Apart from the microphone preamp, the unit is augmented with a compressor, limiter, EQ, de-esser and gate, alongside very comprehensive internal routing and connectivity.

The ISA 430 MKII enables today's recording professional to enjoy the unique sonic contribution of these heritage designs within a single, extremely versatile processor.

Classic Focusrite transformer-based Mic-pre with variable impedance and "Air" feature
Multi format compressor that switch between Focusrite's transparent VCA circuit and a vintage optical circuit
Unmatched flexibility with an incredible variety of insert points and variable signal path arrangements
Ability to function as three separate modular processors - microphone preamp, EQ and dynamics
Precision VU metering of input level, insert 1 or 2 return level, compressor gain reduction or sidechain listen level (switched)
Classic Focusrite EQ design based around an expanded version of the original ISA 110
Post microphone preamp output for the shortest possible signal path
"Listen" feature for precise control over compression, gating, expansion and de-essing
De-esser design based on optical technology for lower distortion and transparency
