Focusrite Red 16Line Thunderbolt 3 Audio Interface

The Focusrite Red 16Line is a powerful, high-performance 16-channel audio interface designed for professional studios and production environments. Combining ultra-low latency, advanced mic preamps, and flexible digital connectivity, it seamlessly integrates into modern workflows — supporting Pro Tools | HD, Thunderbolt computers, Dante networks, and more — without the need for additional option cards.

Equipped with 2 digitally controlled Red Evolution mic preamps, 16 line inputs and outputs via D-sub, and 2 dedicated main monitor outputs, the Red 16Line delivers pristine audio quality with up to 121dB dynamic range and sample rates up to 192kHz. Its dual-port Dante card enables expansion via Ethernet, making it ideal for large-scale, networked audio setups.
