The ISA One Mic Pre is designed from Focusrite's classic, transformer-based Forte console in a rugged and portable chassis. The groundbreaking price is guaranteed to be the lowest at Sam Ash, where you'll also get fast, free delivery.

The Focusrite ISA One is a microphone preamp derived from the best that Focusrite has to offer. Renowned for their superior, ISA transformer-based design, the ISA One finally brings the ultimate in flexibility, performance and affordability to musicians of all levels. Its tone can be described as transparent and uncluttered with a very broad frequency response. And, there are several reasons why it's considered flexible...It's a simple solution for guitarists, vocalists and engineers as it has an independent DI (direct input) channel. There are four selectable variable impedance settings allowing you to get the best possible match or "happy accident" mismatch from your microphones. Its elegant VU meter has a variable configuration for both digital and analog recording mediums and is even calibrated to match the reference points of Pro Tools HD. Finally, there's even a convenient insert point which allows you to add extra processing within the signal chain if required.

For anyone who's ever dreamed about getting a true Focusrite mic pre based on their legendary console designs, it's never been more affordable.

    Comments about Focusrite ISA One Single Channel Microphone Preamp:

    This thing is amazing at this price point. If this is what pro audio sounds like, then I am hooked. After upgrading to a Joemeek ThreeQ a few months ago for vocals I was still not satisfied with the results. I went back in to get a better preamp. I grabbed the ISA One and man there is a night and day difference in audio quality. The ThreeQ has edgy and crunchy highs and a small bottom end. The ISA One has silky highs and a fat and full bottom. I have met the breaking point between amateur and professional vocals.
