The Focusrite ISA428 MKII 4ch Microphone Preamp is a microphone built to help you sound more professional — supplied as genuine Australian stock with local warranty. Utilising the Rupert Neve designed ISA 110 circuit, this is one of the finest preamps you're likely to hear.

Why You’ll Love It

  • Sound more professional — what's better than a Focusrite ISA preamp.
  • Capture the detail of your voice or instrument — not only that, but the instrument DIs are incredible too.
  • Cut down on background noise — a bass guitar plugged straight into the ISA DI input is that punchy, round, crystal clear bass sound you've always dreamed of.
  • Plug in and record — the ISA428 MkII provides four of Focusrite's prestigious transformer-based microphone preamps.
