Focusrite ISA C8X

Original price was: $3,499.99.Current price is: $3,299.99.

Description

ISA C8X combines the trademark ISA sound with comprehensive remote control and all the analogue and digital I/O, routing, and recallability you need to run your entire studio, plus switchable impedance, balanced inserts, and high-pass filtering. The first two channels feature ISA preamps with classic Lundahl LL1538 transformers and Console and 430 Air modes for new tonal options. All eight are fully controllable from the front panel and via Focusrite Control 2.

Key features

  • 2U rack-mounted, 26-in/28-out USB-C audio interface
  • Eight remote-controlled preamps with up to 79dB of gain, two of which are ISA preamps with Lundahl LL1538 transformers
  • All-analogue Console and 430 Air modes for tonal shaping
  • 24-bit/192kHz AD/DA conversion with up to 125dB of dynamic range
  • Additional Sonnox bundles available
