Features

Eight high-quality award-winning Focusrite preamps: The best sounding multi-channel mic pre in its class


Built-in eight channel 24-bit / 96 kHz digital output: Make the most of your interface’s ADAT input. OctoPre MkII connects via its built-in Lightpipe output, with a ‘real world’ dynamic range performance of 110dB

 

Mic preamps optimised for tracking drums: OctoPre MkII is designed not to clip, with preamps optimised to handle extreme levels from sound sources like kick drum and snare

 

Two quality Hi-Z instrument inputs: OctoPre MkII’s first two channels feature DI’s, ready for you to plug in your guitars and bass, instantly accessible on the front fascia

 

5 LED input metering on every channel: OctoPre MkII’s fast-acting 5-LED input meters provide clear reference of input levels, helping you to avoid analogue or digital clipping

 

-10dB Pads on every channel: OctoPre MkII is drum-ready, with 10dB pads to stop hot signals from overdriving the microphone preamp

 

Direct outputs on every channel: For routing and flexibility, especially in the live environment. Each mic pre can be routed to the mixer’s analogue channels, with two mirrored ADAT outputs (44.1) left free to send to digital recorders


48V Phantom power available on every channel: Switched in two groups (1-4 and 5-8) every channel is capable of supplying phantom power, for use with most condenser microphones


State-of-the-art clocking solutions: OctoPre MkII's internal clock delivers a jitter performance of < 10 PPM. For external clocks, a BNC connector is provided and industry-standard JetPLL™ jitter elimination technology is employed
