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.
Eight Award-winning Focusrite Pre-amps
The best sounding multi-channel mic-pre in its class.
Eight Channel 24-bit/96 kHz output
Make the most of your interfaces ADAT input. OctoPre connects via its built-in lightpipe output, with a real world dynamic range performance of 110dB.
Mic-Pres Optimised For Tracking Drums
OctoPre MkII is designed not to clip, with pre-amps optimised to handle extreme levels from sound sources like kick drum and snare.
Two Hi-Z Instrument Inputs
OctoPre MkIIs first two channels feature DIs, ready for you to plug in your Guitars and Bass, instantly accessible on the front fascia.
5 LED Input Metering
OctoPre MkIIs fast-acting 5-LED input meters provide clear reference of input levels, helping you to avoid analogue or digital clipping.
-10dB Pads
OctoPre MkII is drum-ready, with 10dB pads to stop hot signals from overdriving the microphone pre-amp.
Direct Outputs
For routing and flexibility, especially in the live environment. Each mic-pre can be routed to the mixers analogue channels, with two mirrored ADAT outputs (44.1) left free to send to digital recorders.
48V Phantom
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.
