Details

The ISA 430 MkII represents the pinnacle of Focusrite's analogue channel strip technology, bringing together all the classic designs in one comprehensive production tool. Augmented with additional features and flavors, alongside unmatched internal routing and connectivity, the ISA 430 MkII enables today's recording professionals to enjoy the unique sonic contribution of these heritage designs within one extremely versatile processor. With the Producer Pack, Focusrite's iconic status as the leading manufacturer of channel strips remains unrivalled.

From mic impedance switching and 'mic air' effect (a wire-wound inductor for increased spaciousness), to three compressor options (VCA, Vintage Opto and Opto Limit) combined with the compressed/uncompressed 'Blend' feature, the ISA 430 MkII delivers an impressive variety of processing sounds.

Routing and monitoring flexibility has also received a booster. The unique 'Listen' feature (allowing you to hone in on the frequency you wish to affect) is now available on compressor, gate, and expander circuits as well as the ISA 430 MkII's unique phase cancellation-based de-esser circuit. In addition, monitoring and inserts are available at a variety of points along the signal chain. Finally, the ISA 430 MkII features an optional 24-bit 192kHz high performance (122dB A-weighted with jitter below 20 pico seconds) stereo A-D converter, allowing you to retain every nuance of your analogue signal as you flow seamlessly into the digital domain.

Features

  • ISA-series transformer-based preamp
    Featuring mic impedance switching and unique 'mic air' effect (a wire-wound inductor for increased spaciousness)
  • Dual topology compressor
    The ISA 430 MkII is the first ISA to feature both the classic transparent VCA circuit, and a vintage optical circuit with both soft compression and crunch settings.
  • Unmatched flexibility
    The ISA 430 MkII features an incredible variety of insert points and variable signal path arrangements. It can operate as four independent modules.
  • Precision VU metering at multiple points
    Including input level, Insert 1 or 2 Return level, Compressor gain reduction or Sidechain listen level (switched).
  • Classic Focusrite EQ design
    An expanded version of the original ISA 110 with two additional shelving positions.
  • Gate and Expander
    Proprietary Focusrite discrete Class A VCA Gate and Expander designs, now both featuring a 'Listen' option for precision control.
  • De-esser featuring 'De-ess Listen'
    A combination of EQ and phase cancellation are used to create a smoother and less obtrusive result.
  • Optional Stereo 192kHz ADC
    Embodies cutting-edge conversion technology, incorporating Focusrite analoguw circuitry to deliver A/D conversion of the highest quality (128dB dynamic range).
