Focusrite ISA Two – Dual-Channel Vintage-Classic Mic Preamp with Modern Flexibility

ISA Two brings the iconic transformer-based ISA sound to your desktop. Featuring two vintage-style mic preamps with flexible gain, hi-pass filters, variable impedance, and a classic EQ section, it adds rich analog character to vocals, instruments, or track layers—infused with professional versatility and available now at Soundium.

Key Features

• Two ISA transformer-coupled mic preamps: Vintage console tone with subtle harmonic saturation and deep harmonic detail
• Stepped gain with analog trim control: 0–60 dB gain in 5 dB steps, plus ±10 dB fine trim for precise level setting
• Variable impedance options: Four selectable mic input impedance settings—including classic ISA 110—affect tone and response
• High-pass filter and phase reverse: Switchable 75 Hz low-cut and phase invert on each channel for easier tracking and polarity control
• Analog EQ section: Dual shelving EQ with rock shelf (80 Hz & 8 kHz) and presence shift (1.5 kHz) for tonal shaping without plugins
• Insert points on each channel: Route outboard gear before conversion for creative analog processing
• Direct monitoring outputs: Dual analog outputs plus DSP mix outputs for cue or headphone feeds
