With eight channels of Focusrite pre-amplification and a built-in 24-bit / 96 kHz ADAT output, OctoPre MkII is Focusrite's powerful input upgrade for your Pro Tools system, or any digital audio workstation. It's also a great expansion for any analogue or digital console, or hard disk recorder.

The digital output allows users to make the most of often-neglected ADAT inputs; ideal for expanding the number of mic-pre inputs on your interface. Connect OctoPre MkII to your audio interface's ADAT input to create a high quality, multi-channel recording solution, ideal for tracking drums, as well guitars, keyboards, vocals and more.

Focusrite has, over the past two decades, built a reputation as the market leader for high quality recording equipment, with its mic-pre technology as the cornerstone of that enviable reputation. The original mic-pre, as featured in the early Focusrite Forte console, used rotary switched gain controls and high quality audio transformers. This mic-pre is still used by many of the industries greatest producers and has contributed to the sound of countless hit records. Today, Focusrite design equipment for a far greater audience, from professionals to amateur enthusiasts, all with varying budgets.

As with the Red and ISA ranges, the Mic-pre technology found in the OctoPre MkII is designed to the highest possible standards. They uphold the same wide bandwidth philosophy featured in the original forté console, back in 1989. All Focusrite mic-pres feature custom components which have undergone an intense testing and qualification process. With the facts and figures in, Focusrite designs then have to pass the essential listening stage. Any design can measure well on the test bench but only a great design can be qualified in the studio. The FET-based design in the OctoPre MkII is no exception and ensures the same low noise and distortion performance as earlier transformer-based designs. It delivers clarity without colouration and exhibits the signature transparency for which Focusrite have become famous.
