Product Details

The ISA-828 from Focusrite is an eight-channel microphone preamp, featuring original ISA transformer-based preamps with the signature high-end Focusrite sound.

The microphone input stage provides a variable impedance circuit comprising four input impedance settings. Maximum gain is a very healthy 80dB, for use with low output dynamic and ribbon microphones.

Channels one through four include DI inputs that feature high and low impedance options, delivering a comprehensive and accessible DI solution. An eight-channel optional analog to digital converter card makes the ISA-828 the perfect front-end for a DAW.

  • Eight channel microphone preamp featuring original ISA transformer-based preamps
  • Each channel can accept either microphone or line input
  • Channels 1 - 4 also accept instrument inputs for guitars and basses, or vintage synthesizers with high impedance outputs
  • Microphone input can deliver up to 80dB of gain, particularly useful when working with very low output dynamic and ribbon microphones
  • Phantom power and phase switches provided on each input
