Focusrite Scarlett OctoPre
The Focusrite Scarlett OctoPre adds eight mic preamps to an audio interface with an ADAT input and converts their signals to digital at up to 192 kHz.
Its eight channels use Focusrite’s second-generation Scarlett mic preamps, each taking a mic or line signal on a combo XLR input. Conversion is 24-bit, with 109 dB of dynamic range.
Every channel has a switchable 8 dB pad for loud sources such as drums. Phantom power at +48 V switches on in two groups, channels 1 to 4 and 5 to 8.
Inputs 1 and 2 sit on the front panel and switch to instrument mode, with headroom for high-output guitar pickups.
The ADAT optical outputs carry eight channels at 44.1 or 48 kHz, eight at 88.2 or 96 kHz across two cables, and four at 176.4 or 192 kHz. Word clock in and out on BNC lets the OctoPre run as the clock master or follow another device.
Eight balanced line outputs on 1/4-inch TRS jacks carry each channel’s preamp signal. The OctoPre can feed a console on stage while it records over ADAT, or work on its own as an eight-channel mic preamp.
Five-segment LED meters show each channel’s level, and rack ears fit a standard 19-inch rack. Focusrite covers it with a three-year warranty.
