The two Lundahl transformer-based ISA preamps feature all-analog Console and Air 430 modes for new tonal options plus switchable impedance, balanced inserts, and high-pass filtering — all controllable from the front panel and via the Focusrite Control 2 software.\u003c\/p\u003e\n\u003cp\u003eC8X’s two ISA preamps each feature 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 — all digitally controlled via the Focusrite Control 2 app.\u003c\/p\u003e\n\u003cp\u003eConsole mode introduces warm analog saturation and low-end punch, based on a soft-clip circuit with fully variable digital control. 430 Air, lifted directly from the ISA 430 MkII, adds high-end shimmer via an inductor-based high-shelf filter.\u003c\/p\u003e\n\u003cp\u003eInspired by the ISA One’s well-regarded DI channel, the front-panel instrument inputs feature a selectable impedance for preserving the natural tone of guitar, bass, and other instruments. These also run through the ISA transformer circuitry, allowing you to apply both Console and 430 Air modes.\u003c\/p\u003e\n\u003cp\u003eAlongside the two ISA preamps are six remote-controllable, ultra-low-noise Focusrite mic preamps. Each one is designed to reliably capture every nuance with 69dB of clear, detailed gain and includes both analog Air processing for high-end clarity and variable Drive DSP for analog-style harmonic saturation.\u003c\/p\u003e\n\u003cp\u003eWhichever inputs you choose, you’ll be recording and mixing with the same 24-bit\/192kHz AD\/DA converters used in Focusrite’s RedNet range, offering 125dB of dynamic range and ultra-low distortion at 0.00022% THD. And C8X’s two headphone outputs each offer independent level control, extra headroom, and optimised impedance for powerful, detailed playback.\u003c\/p\u003e\n\u003cp\u003eDesigned for patch-bay setups and permanent installations, ISA C8X provides fixed line inputs that let you connect your outboard gear once and avoid awkward re-patching. For immersive formats, the 12 balanced line outputs enable everything from mono up to 7.1.4, with support for up to three monitor groups and switching via both the front panel and Focusrite Control 2. And the entire system is expandable, thanks to 16 additional channels over ADAT and 2 via S\/PDIF for digital gear, plus MIDI and Word Clock I\/O.\u003c\/p\u003e\n\u003cp\u003eFocusrite Control 2 is designed for both desktop and mobile devices, making it easy to manage gain levels, route audio, save and recall preset mixes, and monitor with low latency — wherever you install ISA C8X in your studio. It also supports control of multiple connected interfaces simultaneously, so when expanding your setup via ADAT with other Focusrite Control 2-ready devices, you can switch between them and control each one directly from the app.\u003c\/p\u003e\n\u003cp\u003eISA C8X is future-proof and designed for reliability.
