Eight High Quality Award-winning Focusrite Pre-amps

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 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 quality Hi-Z instrument inputs

OctoPre MkIIs first two channels feature DI, 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 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 pre-amp.

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.


We always quote 'real world' performance figures (measured to the AES17 standard). Some companies choose to quote chipset performance, which is misleading, and here's why.

  • A/D Dynamic Range 110dB 'A-weighted' (all inputs).
  • JetPLL Technology providing superb jitter reduction for class leading converter performance.
  • Clock Jitter < 250 pico seconds.
  • Sample Rate Clock Accuracy: +/- 20PPM.
  • Microphone Input
    • Frequency Response: 20Hz - 20kHz +/- 0.1 dB.
    • THD+N: 0.001% (measured at 1kHz with a 20Hz/22kHz bandpass filter)
    • Noise: EIN > 125dB (128dB analogue to digital): measured at ~60dB of gain with 150 Ohm termination (20Hz/22kHz bandpass filter)
  • Line input
    • Frequency Response: 20Hz - 20kHz +/- 0.1dB.
    • THD+N: < 0.001% (measured with 0dBFS input and 22Hz/22kHz bandpass filter)
    • Noise: -90dBu (22Hz/22kHz bandpass filter)
  • Instrument
    • Frequency Response: 20Hz - 20kHz +/- 0.1dB.
    • THD+N: 0.004% (measured with 0dBu input and 20Hz/22kHz bandpass filter)
    • Noise: -87dBu (20Hz/22kHz bandpass filter)
  • Analogue Output
    • Frequency Response: 20Hz - 20kHz +/- 0.2dB.
    • THD+N < 0.0010% (-100dB) (measured with 0dBFS input 22Hz/22kHz bandpass filter, un-weighted)
  • No. Format Connector Details
  • 2 mic/line/Inst Combi XLR Switch to instrument via front panel
  • 6 mic/line Combi XLR On the rear.
  • No. Format Connector Details
  • 8 Analogue line 1/4" TRS Jack Balanced
  • 16 ADAT Dual lightpipe 8 channels at 96kHz (Lightpipes are mirrored at 48kHz)
Analogue inputs
  • Mic / Line inputs on XLR Combo with auto-switching between Mic (XLR) and Line (TRS)
  • Mic / Line / Instrument on Channels 1 & 2: 2 x XLR Combos on front panel
  • Mic / Line 3-8: 6 x XLR Combo on rear.
  • Instrument: As above, switched to Instrument (inputs 1 & 2 only)
Analogue Outputs
  • Line level 8 x 1/4" TRS Jack
Digital I/O
  • ADAT Out 1 & 2: 8 channels (44.1 / 48kHz, 16 channels total); 4 channels S-MUX (88.2 / 96kHz, 8 channels total)
  • Running at 44.1/48kHz will ultimately provide the user with 2 sets of 8 outputs (mirrored)
  • Internal Universal Input PSU.
Front Panel Indicators
  • Metering of analogue inputs (channels 1-8), 5 segment (-42, -18, -6, -3 and 0dBFS)
  • 4 Sample Rate LEDs (44.1k, 48k, 88.2k & 96k)
  • 2 Sync Source LEDs (Internal, Word Clock)
  • "Lock" Indicator LED
