Focusrite ISA C8X USB-C Audio Interface

Legendary Heritage Meets Immersive Future: The Ultimate Studio Centerpiece

The Focusrite ISA C8X is a professional 26-in, 28-out USB-C audio interface featuring two iconic ISA preamps with Lundahl LL1538 transformers, plus six additional Focusrite preamps. It delivers studio-grade 24-bit/192kHz conversion with 125dB dynamic range, all-analogue Console and 430 Air modes for warmth and shimmer, and remote control via Focusrite Control 2. Built for mixing engineers and professional studios handling everything from vocals to 7.1.4 immersive audio.

The Unmistakable ISA Character
At the heart of the ISA C8X are two remote-controlled ISA preamps featuring Lundahl LL1538 transformers selected by Rupert Neve in 1985. These channels offer up to 79dB of gain and switchable impedance for any microphone. New all-analog Console and 430 Air modes deliver low-end weight and high-end shimmer respectively.

Flagship Digital Precision
The ISA C8X utilizes RedNet-derived 24-bit/192kHz AD/DA converters with 125dB dynamic range and ultra-low distortion (0.00022% THD). Every nuance of your analogue signal is captured with absolute transparency, allowing you to monitor and mix with total confidence.

Modern Workflow, Remotely Controlled
The ISA C8X features Multichannel Auto Gain, automatically setting optimal levels across all eight preamps from the front panel or Focusrite Control 2 app. Digitally controlled preamps let you manage gain, routing, and monitor mixes from desktop or mobile, with instant session recall for complex setups.
