Stereo Audio Switcher
http://www.radialeng.com/
The Backtrack from Radial Engineering is a compact stereo audio switcher, designed for bands running redundant backing tracks on stage, or for switching between any stereo audio sources.
Connect both source devices to the Backtrack via 1/4-inch or 3.5mm connectors, and switch between them or mute them all together 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.
Backtrack has a street price in the US of $349.99.
