Radial Engineering Backtrack Stereo Track Switcher
The Backtrack™ is a stereo audio switcher designed for bands using redundant playback devices on stage. The primary and backup playback devices are both connected to the Backtrack using dual ¼” TRS connectors or stereo 3.5mm inputs, with XLR outputs feeding the PA system. Should the primary playback device fail, an input select switch on the front of the Backtrack allows you to quickly switch to your backup device to ensure your live performance is unaffected. A JR-2™ remote footswitch can be connected, giving you the ability to switch inputs or mute from anywhere on stage. The Backtrack also includes a headphone section with a dedicated level control and a cue select switch, so you can check each playback device silently without affecting the send to the PA. With the Backtrack in your setup, the show will always go on.
