Scorpio is a 32 channel, 36 track mixer-recorder and the most powerful product ever designed by Sound Devices. With 16 mic/line preamplifiers, 32 channels of Dante in and out, AES in and out, 12 analog outputs and multiple headphone outputs, Scorpio is well-suited for any production scenario. A fully-customizable routing matrix enables sound professionals to send any input to any channel, bus, or output. Up to 12 buses may be individually mixed. Due to its compact form factor, the Scorpio is equally at home over-the-shoulder or in a mobile rig.

Scorpio incorporates Sound Devices’ most cutting-edge technology. An ultra-powerful engine comprised of three FPGA circuits and six ARM processors deliver the horsepower needed for the most complex tasks. FPGA-based audio processing with 64-bit data paths ensures the highest sound quality and reliability. The Scorpio also features Sound Devices’ latest and best in analog microphone preamplifier design. These preamps have the smoothest sound and lowest noise of any preamp in the company’s 20-year history and include built-in analog limiters, high pass filters, delay, 3-band EQ and phantom power.

The Scorpio has an internal 256GB SSD and can simultaneously record to two SD cards for redundancy. For additional flexibility, sound professionals can send different files to their choice of media. The companion SD-Remote Android application allows for control of the Scorpio via a large display.

Great attention to detail has been paid to every aspect of the Scorpio’s design. Most common menus are accessible with only one or two button presses, and many menu shortcuts can be achieved with only one hand. Scorpio features a built-in dual L-Mount battery charger and may be powered with L-Mount batteries or via the TA4 DC inputs using smart batteries, NP-1 batteries, or in-line power supplies. The ultra-accurate, fully-featured timecode generator contains its own battery to hold timecode for up to four hours after power off.
