Eight Focusrite Pre-amps
Upholding Focusrite's high bandwidth (20Hz to 200kHz!) philosophy, ensuring low noise and distortion whilst delivering clarity without unwanted artifacts

Two Instrument D.I.s
OctoPre LE's first two channels feature high specification instrument inputs, instantly accessible on the front fascia.

Two ‘Super Channels’
These two channels offer mic impedance matching and instrument DI inputs, alongside phase reverse on the front fascia.

Optional Eight channel CODEC
With eight channels of A-D and D-A via ADAT, OctoPre LE helps make the most of often neglected ADAT* inputs and outputs for tracking and monitoring (see 'Related Products').

Eight Front Panel Line Inputs
Allows quick and easy connection of line level sources

Focusrite has, over the past decade, built a reputation as the market leader for high quality recording equipment, with is 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 is 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 Platinum and Saffire ranges 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 Saffire range 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.

OctoPre LE, the "lite edition" of the company's established OctoPre, brings Focusrite pre-amplification and A/D-D/A conversion to a new level of affordability for DAW and digital console users. OctoPre LE provides eight channels of pristine Focusrite preamps, including two "Super Channels" that offer mic impedance matching and instrument DI inputs plus other features.

With the optional A/D-D/A board installed, OctoPre LE brings more to the DAW via ADAT* lightpipe than ever before, allowing users to make the most of often neglected ADAT* inputs and outputs for tracking and monitoring. In addition, the A/D-D/A option provides wordclock in and out as well as being the only converter in its class to feature 256x clock - a must-have for Pro Tools engineers.

Extremely easy to use, OctoPre LE helps to save session time and engineer heartache. Auto switching front and rear panel inputs and total control of the digital I/O from the front fascia allow the unit to remain racked and patched, with every I/O solution available at the flick of a switch. In typical Focusrite fashion, the OctoPre LE upholds professional standards throughout, boasting class-leading specifications.
