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.

Key Features
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').
