Every ISA model is inspired by Rupert Neve’s original 1985 designs, and delivers the sought-after Focusrite Heritage Sound that lies behind hundreds of top class recordings made in the world’s leading studios. The ISA 430 MkII is the most sophisticated of the range: a complete channel strip in which every element can be used independently or patched in virtually any order – including a classic mic pre, versatile EQ, VCA/optical compressor, expander/gate and de-esser.

• The Most Versatile Channel Strip: The ISA 430 MkII features Focusrite's ultimate heritage sonic signature including transformer-based mic pre, versatile EQ with two dual-range parametrics, compressor with both transparent VCA and vintage optical circuitry, expander/gate, phase-cancellation de-esser and optional 192kHz/24-bit 2-channel AD conversion
• Full Control Over Dynamics: The mic pre suits almost all mics including vintage and 'difficult' models such as ribbons. Variable impedance can be set for transparency or to highlight special features of the mic, such as presence bumps and rolloffs. Switchable additional inductance adds "air" without EQ.
• Four Units in One, Independently Accessible: Use the mic pre, EQ, Dynamics and A-D converter independently, or route them to build powerful simultaneous processors. Re-order different sections to create multiple alternative signal paths.
• Powerful Processing Options: Insert HPF, LPF and EQ into the Dynamics sections for frequency-sensitive processing. Listen function lets you audition the side-chain to fine-tune the effect.
• Control Over Dynamics: Expander/gate features "hysteresis" setting to avoid chattering on difficult signals. De-esser is based on phase cancellation at the chosen frequency, for more natural sound.
• Lundahl LL1538 Input transformer: The original mic transformers used in the original Red modules help to provide the unique sound and performance of this ground-breaking design
• Backlit VU Meter with Variable Calibration: ISA 430MkII has a moving coil VU meter with variable calibration to suit analogue and digital recording media, alongside two six-LED peak meters; inputs can be metered either pre- or post-insert.
