Focusrite ISA TWO

Focusrite ISA Two – Microphone Preamplifier

Overview

The Focusrite ISA Two microphone preamplifier delivers the sonic character of the legendary Forte and Studio consoles in a compact 1U rackmount chassis. Featuring two independent channels, it provides flexible connectivity for microphones, line-level sources, and direct instrument inputs.

A variable impedance selector allows precise tonal shaping, enabling engineers to introduce the desired warmth while maintaining exceptional clarity and detail. This makes the ISA Two an ideal choice for professional recording environments.

Sound Character and Design

The ISA series has a distinguished heritage based on its transformer-driven analog circuitry. Since its introduction in 1985, this design has become a benchmark in professional studios for its outstanding transparency.

Transformer core saturation introduces a subtle analog warmth while preserving open and unrestricted high-frequency response. This unique combination of warmth and transparency defines the recognizable Focusrite sound that continues to be highly sought after in top studios worldwide.
