Since 1985, Focusrite has been a name synonymous with no-compromise mic pres following the creation of the ISA 110 for Sir George Martin's Neve console at Air Studios. The legacy of the original ISA 110 lives on today, not only in the ISA range itself, but also in every mic pre we design.
Standing for 'Input Signal Amplifier', the ISA range was born out of the original Focusrite Forte console of the late 80's, and later the Focusrite Studio Console. The core modules from these consoles live on with Focusrite's current range of ISA products, which have in themselves also become recording classics, and the choice of the world's finest producers and engineers. All ISA products use the Lundahl LL1538 input transformer and a custom Zobel network, both of which contribute to their sought-after sound.
