The ISA428 MkII from Focusrite is a four-channel microphone preamp featuring Focusrite's transformer-based preamps. You get selectable input impedance, direct instrument inputs and an optional eight channels of high-quality analog to digital conversion. As such, this unit is a perfect front end for the discerning audio engineer.

ISA microphone preamps hold a reputation for delivering transparency along with subtle warmth derived from transformer core saturation. The addition of a variable impedance circuit allows users to perfectly match the preamp with any microphone, or to use different settings creatively to shape the sound of the microphone.

The incredibly broad frequency response of Focusrite preamps (close to 200 kHz on top) ensures accurate phase response across the range of human hearing, with the roll-off point entirely outside the range of human hearing. Warm, beautifully open, unrestricted high frequencies is a classic hallmark of the Focusrite designs to which this preamp owes its design.

If needed, the eight-channel analog converter utilizes high-quality Burr-Brown amplifiers and PCM4220 A-D converter chips within Focusrite's analog circuitry. Specifications include a dynamic range of 122dB and jitter performance below 250 picoseconds. Due to the convenient 25-pin D-type connector, it integrates seamlessly with most digital workstations, including Pro Tools.

For your convenience we include a road case that stacks with most other "rackable" cases. So feel free to rent this for a live production or take it to a studio, knowing that it is protected and ready to rock no matter how you want to use it.

Included with your rental:

  • Focusrite ISA428 MkII Rackmount 4-Channel Microphone Preamp
  • 6 foot AC power cord
  • 2U Stackable Road Case
