Overview

Now in its second generation, the ISA 428 Mk II incorporates four of Focusrite’s renowned mic pres in a simple-to-operate 2U enclosure, placing four mic preamps, instrument inputs and line ins at your fingertips. The original Focusrite mic pre was designed to suit the microphones of the time; today’s model makes one small change, adding three additional input impedances to the classic ISA110 setting, allowing you to match any microphone, old or new, and access a wide range of sounds, from the character and warmth of a vintage mic to the clear transparency of a modern design. Or you can experiment and bring out just the qualities you want.

  • Four ISA series transformer-based preamps

  • Selectable impedance (low, ISA 110, Med, High
  • 48V Phantom Power
  • Supports instrument, line, and send/return inputs
  • Variable High-Pass Filter
