With eight pristine class A Focusrite mic pre’s, eight compressor/limiters, and almost all the interface options known to man, OctoPre is the perfect partner for any Digital audio workstation, making high quality, multi-channel recording (eg. Drums and synths) easy.
Equally, it can be utilised as an instant location recording solution, (as part of an ultra-compact 8-channel system with a laptop,) or as an additional set of pre-amps for any analogue or digital console or hard disk recorder. Each channel boasts the award-winning pre-amp featured in VoiceMaster PRO, alongside a revolutionary dynamics circuit, ensuring transparency and warmth with total control. The first two ‘Super channels’ also feature phase reverse, as well as TRS Jack inputs on the front fascia for quick and easy, DI-free plug-in.
Finally, the high quality digital converter options cover almost every interfacing eventuality. Up to sixteen digital outputs can run simultaneously with any mix of analogue outputs, and all the settings are adjustable, directly from the front fascia. With this entire package fitting into a single 1U chassis, OctoPre sets the standard for multi-channel recording solutions.

Key Features
Eight award-winning Class A discrete transistor-based Focusrite pre-amps This pre-amp demonstrates the same wide bandwidth philosophy featured in the original vintage Focusrite units, ensuring low noise and distortion.
Eight independent Focusrite Compressors/Limiters Revolutionary circuit design allows dynamics to be handled via a single control.
Up to 16 digital outputs (24bit, 96kHz) Two high quality 8-Channel A/D converters are available. Both converters are 24 bit and 128 x over-sampled, handling sample rates of up to 96kHz, but can dither down to 20 or 16 bit.
Two ‘Super Channels’ No separate D.I. is required, with TRS Jack inputs and phase reverse on the front fascia.
