Roland SI-24 Studio Interface

The SI-24 Studio Interface is the perfect way to expand the analog inputs and mixing capabilities of a VS-2400. This compact mixer and hardware control surface sports eight XLR inputs with phantom power, which can be routed digitally to the V-Studio using the 8-channel R-BUS port. The SI-24's 13 motorized faders provide additional realtime control when mixing, making the SI-24 a valuable upgrade.

Surface Features

* Compact digital mixer and control surface for use with VS-2400
* 8 XLR inputs with phantom power and 24-bit/96kHz sound quality
* 6 analog outputs, plus S/PDIF digital I/O in coaxial and optical formats
* 13 motorized faders and 12 knobs for additional realtime control when mixing
* Route signal to VS-2480/2400 digitally using an 8-channel R-BUS port
