From ISA Heritage to the Clarett+ Series: A Modern Classic
Clarett+ continues Focusrite's signature by bringing the spirit of legendary consoles into a compact rack format. The "Air" mode is achieved here by a relay-controlled analog circuit that adapts impedance (2.2 kOhms) and applies two cumulative high shelving filters to recapture the brightness and openness of ISA channels. The converters have been optimized to further reduce noise and distortion while offering greater depth and headroom.
Who Is the Clarett+ OctoPre For?
Perfect for demanding studios, mobile producers, and live recording venues, it instantly adds eight channels of high-end preamplification to an ADAT interface. Low latency, phantom power switchable by groups, and precise level indicators make multi-mic sessions easier, from drum kits to string ensembles.

Questions frequently asked
Can the Focusrite Clarett+ Octopre add 8 preamps to an ADAT interface?
The two ADAT outputs allow adding eight preamp channels to a compatible interface. Two ADAT inputs are also provided for digital expansion at various sample rates.
How does the Air mode on the preamps work?
Each channel features a relay-controlled analog Air mode. It adjusts the impedance to 2.2 kOhms and applies two high shelving filters to add brightness and openness to the signal.
Can a guitar be plugged in directly on the front panel?
Two front panel instrument inputs use wide-bandwidth JFET stages. This design is intended to preserve a natural feel when recording guitar or bass.
What analog connections and inserts are available?
Eight independent analog inserts allow integration of external processors during tracking. The eight mic inputs are combo XLR/jack format, while the line outputs use a Sub-D25 connector.
What is the stated conversion quality and dynamic range?
The A/D and D/A conversion operates at 24-bit / 192 kHz. The dynamic range reaches up to 118 dB, and the equivalent input noise is specified down to -129 dBu. The preamps offer up to 57 dB of gain.
