New switching device intended for concerts where backing tracks are used to reinforce the performance.

Vancouver, Canada (July 31, 2019)—Radial Engineering has shipped its SW8-USB auto-switcher and USB playback interface.

The SW8-USB is an eight-channel switching device designed primarily for live concerts where backing tracks are used to reinforce the performance. If a primary playback source suffers a failure or dropout, the SW8-USB can switch to a backup source mid-performance. The switching can be done automatically by the SW8-USB, manually using a switch on the front panel or by remote control.

The SW8-USB allows users to connect directly to a playback computers over USB, eliminating the need for additional audio interfaces which in turn reduce the weight and cost of a redundant system.

The SW8-USB is equipped with two USB connectors and 24-bit/192 kHz digital audio converters that provide eight channels of audio playback over balanced XLR outputs. Designed to feed the PA system, the mic-level outputs are transformer isolated to eliminate noise from ground loops, and can also be set to line-level operation. Additional line-level outputs are provided for local monitoring of playback signals, with the choice of DB25 or 1/4” TRS connections.

In addition to passing audio over USB, the SW8-USB is also able to function as a MIDI interface, allowing use with show control systems to trigger lighting or video cues, or to control and synchronize audio playback on primary and backup computers. For larger shows that require more than eight channels of audio playback, up to three SW8-USB units can be linked together for a total of 24 output channels.
