The ISA sound, evolved
The ISA story starts in 1985 with a request from Sir George Martin to Rupert Neve: build a no-compromise mic preamp. That circuit became the foundation of every ISA product made since. 40 years on, it lives in ISA C8X — Focusrite's first ISA audio interface, housed in anodised aluminium in Focusrite's original blue colour, with heritage transformer sound in a 26-in, 28-out USB-C interface built for the modern studio.
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 setup. The two ISA preamps are based on classic Lundahl transformers and feature all-analogue Console and 430 Air modes for new tonal options plus switchable impedance, balanced inserts, and high-pass filtering. All eight of ISA C8X’s preamps are fully controllable from the front panel and via the Focusrite Control 2 software.
Key Features
-
2U rack-mounted, 26x28 USB audio interface
Capture, route, and mix sessions of any size with 26 inputs and 28 outputs of analogue and digital audio. -
Two remote-controllable ISA preamps
Featuring Lundahl LL1538 input transformers that add subtle warmth and body to any signal, plus balanced inserts, stepped and fine gain control, switchable impedance, high-pass filter, and up to 79dB of gain. -
Analogue tone at the touch of a button
The two ISA preamps include relay-switchable circuitry, enabling variable saturation via Console mode and high-end lift with 430 Air mode. -
Six remote-controllable, ultra-low-noise mic preamps
Alongside the two ISA preamps are six remote-controllable, ultra-low-noise Focusrite mic preamps designed to reliably capture every nuance with 69dB of clear, detailed gain plus analogue Air mode and variable Drive DSP. -
Two front-panel, transformer-based instrument inputs
Both are routed through the Lundahl transformers for console-like feel and feature selectable impedance to enhance the natural tone of guitar, bass, and other instruments. Console and 430 Air modes are also available here for added analogue character. -
Eight dedicated fixed-gain balanced line inputs
Designed for patch-bay setups and permanent installations, ISA C8X provides fixed line inputs that let you connect your outboard gear and avoid re-patching. -
Automatically set your levels
Enable Auto Gain and let ISA C8X set gain automatically across all eight preamps in seconds, directly from the front panel or via Focusrite Control 2 desktop and mobile apps. -
Flagship AD/DA conversion
Record and mix with the same 24-bit/192kHz AD/DA converters used in Focusrite’s RedNet range, offering 125dB of dynamic range with 0.00022% THD. -
12 balanced line outputs
Work in mono, stereo, or up to 7.1.4, with three monitor groups and front-panel or remote switching. A professional +24dBu maximum output level matches the line inputs for consistent line-up levels, with 125dB of A-weighted dynamic range; outputs 1 and 2 are available on both XLR and TRS. -
Two dedicated class AB headphone outputs
Each with independent level control, extra headroom, and optimised impedance for powerful, detailed playback. -
ADAT, S/PDIF, MIDI, and Word Clock
Expand your setup with 16 additional channels over ADAT and two channels via SPDIF for up to 26 channels of recording, plus S/PDIF, MIDI, and Word Clock connectivity. -
Focusrite Control 2 software and mobile app
When front-panel control isn’t practical, Focusrite Control 2 makes it easy to remotely manage, save, and recall your mixes and routing, as well as monitor with low-latency across multiple connected interfaces. -
Award-winning support
