Classic Mic Pre With Independent DI. Featuring a rugged, portable all-metal enclosure, ISA One combines the classic Focusrite microphone preamp with a flexible, independent DI channel and optional 192kHz precision A-D conversion. At the heart of the ISA range is the microphone preamplifier with its Lundahl input transformer – essentially the same circuit, based on the original ISA 110, that has been used for 30 years in successive Focusrite designs. The input transformer imparts a special character to the sound that can't be truly emulated in any other way, while the modern twist of variable input impedance allows for a new degree of flexibility.
Whether you're an artist, engineer or producer, you'll appreciate the versatility of the ISA One, with its front-panel DI input. The DI includes low/high impedance switching and an amplifier output, and its own feed to the optional A-D converter and separate rear-panel XLR output.
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.
