Radial Engineering SW8 8-Channel Backing Track Switch with D-Subs, 1/4" Inputs and Isolated DI Outputs

The Radial SW8 is an 8-channel auto-switcher that allows you to set up a redundant backup system by automatically switching between two sources such as a pair of digital recorders, computers or network systems.

With huge productions in mind, where backing tracks are used for orchestration, vocals and sound effects, the SW8 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. It monitors any continuous audio signal like SMPTE on the main playback system, and should that signal drop it will automatically switch to the backup. Toggling the inputs can also be done manually on the front panel or by using a footswitch like the Radial JR2 (sold separately). Multiple SW8s can be linked together for systems that are larger than eight channels.
