With eight channels of Focusrite pre-amplification and a built-in 24-bit / 96 kHz ADAT output, OctoPre MkII is Focusrites powerful input upgrade for your Pro Tools system, or any digital audio workstation. Its also a great expansion for any analogue or digital console, or hard disk recorder.
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 interfaces ADAT input to create a high quality, multi-channel recording solution, ideal for tracking drums, as well guitars, keyboards, vocals and more.
Key Focusrite OCTOPRE-MKII Features: Eight High Quality Award-winning Focusrite Pre-amps Built-in eight channel 24-bit / 96 kHz digital output
Make the most of your interfaces ADAT input.OctoPre connects via its built-in lightpipe output, with a real worlddynamic range performance of 110dB. Mic-pres optimised for tracking drums
OctoPre MkII is designed not to clip, with pre-ampsoptimised to handle extreme levels from sound sources like kick drum andsnare. Two quality Hi-Z instrument inputs
OctoPre MkIIs first two channels feature DIs, ready foryou to plug in your Guitars and Bass, instantly accessible on the frontfascia. 5 LED input metering on every channel
OctoPre MkIIs fast-acting 5-LED input meters provideclear reference of input levels, helping you to avoid analogue or digitalclipping. -10dB Pads on every channel
OctoPre MkII is drum-ready, with 10dB pads to stop hotsignals from overdriving the microphone pre-amp. Direct outputs on every channel
For routing and flexibility, especially in the liveenvironment. Each mic-pre can be routed to the mixers analogue channels, withtwo 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 iscapable of supplying phantom power, for use with most condenser microphones. State-of-the-art Clocking Solutions
OctoPre MkII's internal clockdelivers a jitter performance of < 10 PPM. For external clocks, a BNCconnector is provided and industry-standard JetPLL jitter eliminationtechnology is employed.
