The Red 16Line is a 1U rack model with 64-ins and out, is Pro Tools HD-compliant and has Thunderbolt 3 connectivity. It has low-latency Focusrite converters, its own Red Evolution mic preamps, and up to 121dB of dynamic range. This is a serious unit obviously geared for pro audio and studio use.
The RedNet X2P is a much simpler proposition, being a desktop format unit with 2-in and 2-out, two Red Evolution mic pres, remote control functionality when combined with a power-over Ethernet switch, but can also be sued with mains power. It has inputs for mix control, and control lockout of the mic pre and output settings.
Focusrite are distributed in Australia through Innovative Music Australia.
