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.
The Focusrite Red range is the best choice for professionals who work in Pro Tools™ | HD and other DAWs — on both Mac and PC. With both mini-DigiLink and Thunderbolt 3 connections, it's possible to instantly switch between Pro Tools and other DAW applications without the need to reconfigure your audio settings. Simply change the host mode either in RedNet Control software, or using the Red 8Line front panel, to change DAWs in seconds. This ability to quickly switch between production environments means you'll never lose that moment of inspiration, or leave your clients waiting.
Red 8Line features the latest implementation of Thunderbolt 3, with Focusrite's session-proven, ultra-low-latency, rock-solid Thunderbolt drivers. This speed provides the flexibility to use DAW plug-ins in real time, so you can harness the processing power of your DAW to track through plug-ins and record virtual instruments. With two Thunderbolt 3 ports as standard, it's also possible to daisy-chain Thunderbolt devices, such as third-party plug-in accelerators, hard drives, external 4K displays, processing units and Thunderbolt hubs.
On-board Dante connectivity enables Red 8Line to communicate with industry-standard Audio-over-IP equipment from hundreds of manufacturers. Dante makes it easy to expand your system, embrace new ways of working, and discover rapid system expansion using Focusrite RedNet interfaces or devices from third parties such as Neve, Yamaha and DiGiCo. Red 8Line has built-in monitor control for mono, stereo and multi-channel monitoring environments up to 7.1.2. Compatibility with the new Focusrite RedNet R1 desktop remote controller allows even greater flexibility, and customised presets for immersive monitoring environments including Dolby Atmos®.
