Legendary ISA Preamps with Complete Control
At its core, the ISA C8X features two classic ISA mic preamps that provide subtle warmth, depth, and clarity thanks to Lundahl LL1538 transformers. Each preamp offers stepped and fine gain control, switchable input impedance, high-pass filtering, balanced insert points, and up to 79 dB of gain. Control is possible both on the front panel and remotely through software, ensuring ultimate flexibility.
Analogues Tone Shaping for Signature Sound
The ISA C8X delivers authentic analogue tone shaping inspired by vintage studio hardware. Console mode introduces soft saturation and weight, enhancing low-end warmth, while 430 Air mode adds shimmer and high-frequency clarity with an inductor-driven high-shelf design. These modes allow you to achieve rich, characterful tones without external processors.
Six Extra Ultra-Quiet Mic Preamps
Alongside the ISA channels, six additional Focusrite mic preamps provide pristine sound with up to 69 dB gain. These preamps feature analogue Air processing for added brightness and a Drive control that adds harmonic saturation, enabling tonal versatility from transparent to distinctive.
Premium Conversion for Accurate Audio
ISA C8X uses high-grade AD/DA converters from Focusrite’s RedNet range, delivering pristine audio quality with 24-bit/192 kHz resolution, 125 dB dynamic range, and exceptionally low distortion (0.00022% THD). This ensures every recording and playback is clear and true-to-source.
