Clarity Redefined

The Clarett+ OctoPre is the eight-channel ADAT preamp for both the aspiring and established engineer. Eight high headroom, low noise, and low distortion Clarett+ preamps — featuring All-analogue Air with relay-controlled circuitry — capture drums, vocals, and acoustic instruments with superb clarity. 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. Exceptional D-A conversion ensures that audio quality is preserved when sending audio to analogue compressors, EQs, and effects.

Add Clarett+ OctoPre to a 2Pre, 4Pre or 8Pre to expand your I/O easily and consistently via ADAT, so that you can record a whole band together while maintaining analogue purity and clarity as well as bringing the classic Focusrite Studio Console sound to your recordings.

Key Features

Get the classic Focusrite sound with All-analogue Air

Get closer to the origins of Focusrite with premium, relay-controlled analogue circuitry on every preamp that emulates the classic Focusrite ISA 110, as featured on the original Focusrite Studio Console. When Air is engaged it switches the impedance to 2.2k? and adds two cumulative high shelves, totalling a 4dB boost in the high frequencies.



Capture the truest version of your sound with Clarett+ Mic Pre

Achieve clear recordings in any session. With 118dB of dynamic range and 129dBu EIN, the natural sound of source signals is preserved. The fully balanced signal path ensures inbound signals are clean and with ultra-low noise — giving sessions the professional Focusrite sound.



Stay plugged in with inserts on every channel

Clarett+ OctoPre’s eight dedicated channel inserts allow you to track through your favourite outboard and capture its true character. Easily add analogue equipment to the signal path with our flexible insert design.



Clear, accurate multi-tracking with improved A-D converters

Multi-track with confidence and handle any recording session. Offering ultra-low noise and ultra-low distortion, Clarett+ OctoPre’s A-D conversion combined with the powerful preamps give professional-sounding tracks ready for mixing.



Preserve your signature style with improved D-A converters

Clarett+ OctoPre’s exceptional D-A conversion allows engineers to easily process audio in their signature style, confident that audio quality is preserved when sending audio to analogue compressors, EQs, and effects. Connect Clarett+ OctoPre to a Clarett+ 8Pre via ADAT and send 16 channels to a mixer.



Premium-quality audio 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 and bring the classic Focusrite sound to their recordings by connecting to an ADAT-enabled interface, benefitting from the premium quality offered by Clarett+ OctoPre.



Preserve the natural tone of your guitar

Capture the true characteristics of guitars with Clarett+ OctoPre’s JFET guitar inputs. Wide input bandwidth retains the purity of high frequencies and feels like you are plugging straight into an amp.
