Product Description

Key Features

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 groundbreaking 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.
