Radial Engineering SW8-USB 8-Channel Interface with Dual USB Inputs and MTC for Redundant Playback Systems

A streamlined solution for employing redundant playback systems live and onstage, Radial Engineering's SW8-USB Auto-Switcher USB interface is designed to execute simply for peace of mind in any professional setting. Connect directly to primary and back up computers via dual USB inputs for eight channels of high-quality audio.

With huge productions in mind, where backing tracks are used for orchestration, vocals and sound effects, the SW8-USB utilizes an adjustable gate to detect a machine malfunction and automatically switches over to a second back-up machine, keeping the performance flawless to the audience's ears. Dual USB inputs with separate 24-bit, 192 kHz converters allow two MacOS computers to be connected simultaneously, allowing the digital workstations on both to connect with the SW8-USB as an audio and MIDI interface. The optional JR-2 footswitch (sold separately) can be used to toggle USB inputs with just a tap. Up to three SW8-USB may be linked together for up to 24 channels of playback.
