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 professional to enjoy the unique sonic contribution of these heritage designs within one extremely versatile processor.
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 ISA430 MkII delivers a 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 24bit-192kHz high performance (123dB 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.
