Focusrite Clarett+ OctoPre – 8-Channel ADAT Preamp with Hitmaker Expansion Bundle

The Focusrite Clarett+ OctoPre is a high-end, 8-channel microphone preamp with built-in A/D and D/A conversion, designed for modern professional and home studios. This unit delivers exceptional audio quality, wide dynamic range, outstanding clarity, and flexible connectivity thanks to its dual ADAT ports. Ideal for producers, engineers, and musicians looking to expand their setup with eight premium input and output channels — without compromising audio performance.

Key Features

Equipped with eight Clarett+ microphone preamps, each channel supports independent activation of the analog Air mode. This feature emulates the sound of classic ISA preamps, modifying the input impedance and adding a subtle high-end boost for extra presence and brightness. Two front-panel Hi-Z instrument inputs (JFET) allow you to plug electric guitars or basses directly into the unit without the need for a DI box. Each channel also includes a dedicated insert point (TRS 6.3 mm), letting you add external processors like compressors or EQs before the A/D conversion.

Expand Your Studio with Confidence

Focusrite Clarett+ OctoPre is the perfect choice for anyone looking to increase their I/O count while maintaining pristine audio quality. With dual ADAT inputs and outputs, you can transmit 8 channels at 44.1/48 kHz, or 4 channels at 176.4/192 kHz via SMUX. The DB25 output delivers eight balanced line outputs, suitable for analog summing, external mixing desks, or monitor feeds. Integrated Word Clock I/O (BNC) ensures easy synchronization with other studio gear.

Use Cases

Whether you're working in a small home setup or a large commercial studio, the Clarett+ OctoPre is built to meet the demands of serious audio production. It's ideal for recording full bands, drums, vocals, or acoustic instruments — wherever clean and detailed sound is essential. With compatibility across devices supporting ADAT, including Focusrite Scarlett 18i20 and Clarett+ interfaces, it becomes a versatile expansion tool. High sample rates, onboard inserts, and the Air mode make it an outstanding choice for tracking, mixing, and even live sound applications.
