Focusrite ISA One Desktop Microphone Preamp

The Focusrite ISA One Preamp is an amazing method to get into the Forte console’s history in an ultra-portable manner. The ISA One is based on the original ISA 110’s topology, including the Lundahl L1538 transformer and Zobel network. All of the bases are covered with inputs for microphone, line, and instrument-level sources. A variable impedance selector also allows you to fine-tune the response. Furthermore, the ISA One’s instrument- and microphone-level inputs operate in simultaneously, allowing you to combine direct signals.

ISA preamp in a portable metal chassis

Focusrite’s ISA preamps are designed to give you the same classic performance and sound as the legendary Forte console, which is often thought of as the pinnacle of analog recording. The ISA One gives you this preamp design in a portable desktop form factor. You no longer have to go through the hassle of un-racking and re-racking your gear when you have to track elsewhere. And forget hiring a team and truck to move a Forte! Now you can just grab your ISA One and go.

Selectable impedance, perfect for matching with any microphone

The microphone input on the ISA One offers the awesome addition of impedance matching. Since so many mics like to see a different impedance at the preamp, one size doesn’t necessarily fit all. With the ISA One, you come prepared. You can select between four different levels to match with the mic you’re using. Or break the rules and find an “incorrect” sound that works for your needs! No matter the mic you choose, you’ll be covered by the ISA One.

Mic, line, and direct instrument inputs offer great tracking options

One of the best features of the ISA One is all of the tracking options you get in such a compact package. You get mic-, line-, and instrument-level inputs – you can actually blend an instrument input and a mic input at the same time. Then you can listen back to your mix through the headphones out, while the sounds you need get on your track.
