Expand your DAW setup or digital console with 8 channels of clean, high-headroom Focusrite amplification. The Focusrite OctoPre MkII is a 1U rackmount 8-channel mic/line preamplifier equipped with 24-bit / 96 kHz ADAT optical outputs, making it the industry standard for adding inputs to any ADAT-equipped audio interface (such as a Focusrite Scarlett 18i20, Clarett, Apollo, or RME unit).

Channels 1 and 2 feature front-panel combination XLR/TRS inputs with selectable Hi-Z instrument DIs for tracking guitars and basses directly, while channels 3 through 8 feature rear-panel balanced inputs. Each channel provides independent gain control, a -10 dB pad for loud sources like snare and kick drums, and fast 5-segment LED metering.

Key Features:

• 8 Focusrite Preamps: Transparent, low-noise preamplification optimized for tracking full drum kits, multi-mic setups, and live ensembles.

• 24-bit / 96 kHz ADAT Output: Dual optical Lightpipe outputs supporting 8 channels up to 48 kHz or 4 channels per port via S/MUX at 88.2/96 kHz.

• Dual Front-Panel Instrument DIs: Quick access on Channels 1 & 2 for high-impedance guitar/bass tracking without external direct boxes.

• Individual Channel Pads: Dedicated -10 dB pad per channel to prevent clipping on high-output transients.

• Analog Direct Outs: 8 balanced 1/4" TRS direct outputs allow you to route preamps directly into an analog desk, outboard hardware, or secondary recorder.

• Switchable +48V Phantom Power: Two discrete 4-channel phantom banks (1–4 and 5–8) for condenser mics and active direct boxes.

• Clocking Flexibility: Internal clocking (44.1k, 48k, 88.2k, 96k) and rear-panel BNC Word Clock In with JetPLL jitter-reduction technology.
