Focusrite Pro RED-8LINE 58-in, 64-out Thunderbolt 3 Audio Interface

Red 8Line is a 58-input, 64-output, Thunderbolt™ 3 audio interface that features two Red Evolution mic pres, independent L/R monitor outs, eight balanced line inputs and outputs on DB25 connectors; 32 channels of Dante® I/O; 16-channel ADAT input and output (at 48kHz), and stereo S/PDIF input and output. As with other Red interfaces, it has professional-grade 24-bit/192kHz A-D and D-A conversion for no-compromise recording and audio playback. With 119dB dynamic range A-D and 121dB dynamic range D-A (A-Weighted), the converters have been expertly selected and calibrated by Focusrite to provide the best balance of sound quality, dynamic range, and conversion latency.

With the Windows 10 driver software (download available from Focusrite), the Red interfaces are Windows-compatible for Windows 10 users with the appropriate Thunderbolt 3 hardware.
