Focusrite CLARETT+ OCTOPRE

Focusrite Clarett+ OctoPre – 8-Channel ADAT Mic Preamp

The Clarett+ OctoPre from Focusrite is an eight-channel ADAT mic preamp designed to deliver pure analogue character to any ADAT-enabled interface. It brings the depth and punch of a large-format studio console directly into your recording setup.

Eight Clarett mic preamps provide exceptional headroom, clarity and detail. The fully analogue Air mode with impedance switching recreates the legendary tone of the Focusrite ISA range, adding presence and openness to drums, guitars and vocals.

Two Hi-Z JFET instrument inputs capture the true feel and response of a guitar plugged into a real amplifier. High-performance A-D / D-A converters deliver up to 124 dB dynamic range with ultra-low noise and distortion.

Easily expand a Clarett+ 2Pre, 4Pre or 8Pre via ADAT and record full band sessions while maintaining analogue purity and clarity.
