Focusrite OCtoPre MKII Main 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.
