The Scarlett OctoPre is the ideal 8-channel expansion for any Scarlett — or other digital interface with ADAT inputs. ADAT is a simple and easy way of increasing the number of simultaneous recording channels available in your studio. With eight channels of Focusrite's 2nd generation Scarlett preamps and precision A-D conversion at sample rates up to 192 kHz, Scarlett OctoPre is the ideal way of increasing the number of inputs in your studio. It also offers eight balanced line outputs, sourced directly from their respective mic preamps for use on stage in a live environment.

Eight natural-sounding 2nd generation Scarlett mic/line inputs deliver high headroom, plenty of clean gain, low noise and minimal distortion — ideal for tracking drums as well guitars, keyboards, vocals and more. The front panel features two newly-designed instrument inputs with extended headroom. ADAT outputs let you connect to any interface or digital system with ADAT optical inputs, and analogue line outputs let you feed an analogue console at the same time as recording with the digital outputs.

The sound of Scarlett - and more of it

 

Eight Scarlett mic preamps

Scarlett OctoPre features eight Scarlett mic inputs – balanced line inputs too – all running through Focusrite precision 24-bit conversion at up to 192kHz resolution with 109dB dynamic range.

 

Dual front-panel instrument inputs

Two high-headroom instrument inputs will handle high output guitar pickups and are right there on the front panel for easy access.

 

 

Plenty of headroom. Pads for the most extreme inputs

With high-headroom inputs and a pad on every channel, Scarlett OctoPre is ideal for tracking drums as well guitars, keyboards, vocals – and more.

 

Outputs for live or standalone use

Eight balanced line outputs, sourced directly from the inputs, allow Scarlett OctoPre to be used in a live situation whilst capturing the recording via the digital ADAT output.
