The Clarett+ OctoPre is the eight-channel ADAT preamp designed to bring pure analogue sound to your studio.

The eight Clarett preamps have been meticulously engineered to bring authentic large-format studio sound to any ADAT enabled interface. All-analogue Air mode, with impedance switching, recreates the legendary effect of Focusrite's ISA mic pres, adding clarity and presence to drums, guitars and vocals. Two JFET instrument inputs capture the true characteristics of guitars, just like plugging into an amp. High-quality A-D/D-A converters brings audio clarity to studio tracking sessions with high dynamic range, ultra-low noise, and ultra-low distortion. Ten balanced outputs are hum-free for pristine monitoring, mixing and mastering with studio monitors. Add Clarett+ OctoPre to a 2Pre, 4Pre or 8Pre to expand your I/O easily and consistently via ADAT. Record the whole band together while maintaining analogue purity and clarity as well as bringing the classic Focusrite Studio Console sound to your recordings.

  • Eight inputs, eight outputs; eight Clarett mic pres with two Hi-Z JFET instrument inputs, eight balanced outputs and eight-in, eight-out over ADAT.
  • All-analogue Air mode, with impedance switching, adds presence and clarity to your recordings, recreating the legendary character of the ISA.
  • Low distortion, 24-bit/192 kHz converters with up to 124dB dynamic range deliver incredible sound quality.
  • High-quality inserts preserve the sound of your studio outboard, and effortlessly bring your favourite hardware into your session.
  • ADAT connectivity to bring pure sound to any studio.
  • Three-year warranty and award-winning customer support for life.
  • The truest version of your sound

    From jazz to heavy metal drums, capture the performer’s vision — with masses of headroom so that you can focus on the session without having to constantly adjust gain staging. For the techie engineer, the fully balanced signal path ensures inbound signals are clean and have no unwanted colouration. Be confident in a recording that is right first time and captures the energy of a live session accurately.

  • Get the console sound

    All-analogue Air with relay-controlled circuitry is the engineer’s secret weapon. It captures transients on drums, makes vocals shine, and ensures a precise, clear recording. When Air is engaged the Clarett+ OctoPre switches impedance to 2.2kΩ and adds two cumulative high shelves, totalling a 4dB boost in the high frequencies, which recreates the sound of the classic Focusrite ISA 110.

Maintain your signature style

Exceptional D-A conversion ensures that audio quality is preserved when sending audio to analogue compressors, EQs and effects. You can easily process audio in your signature style and benefit from integrating your outboard into your workflow to achieve accurate results. Send 16 channels of high-quality audio from your computer by connecting a Clarett+ OctoPre to a Clarett+ 8Pre via ADAT — perfect for integrating an analogue mixer into your workflow.

Premium-quality over ADAT

Add Clarett+ OctoPre to a 2Pre, 4Pre or 8Pre to expand your I/O easily and consistently via ADAT. Non-Clarett+ users can upgrade to a professional standard by connecting to any ADAT-enabled interface, bringing the classic Focusrite sound to their recordings as well as the premium quality offered by Clarett+ OctoPre.
