Radial Engineering Backtrack

Connect both source devices to the Backtrack via ¼" or 3.5mm connectors, and switch between them or mute them altogether using the front panel controls or a JR-2 remote footswitch. A headphone output with level control allows you to check either input at any time, and ¼" monitor outputs feed powered speakers for playback on stage. Dual XLR outputs feed the PA system, and feature a ground lift switch and transformer isolation to prevent buzz and hum from ground loops. The Backtrack lets you easily connect a laptop computer, MP3 player, or recording interface and ensure that even if your primary backing track source fails, the show still goes on.
