Radial Engineering is now shipping the Backtrack compact stereo audio switcher. The Backtrack is an ideal tool for bands running redundant backing tracks on stage, or for switching between any stereo audio sources.
Connecting your playback devices to the Backtrack is easy via either dual quarter-inch TRS or 3.5mm stereo inputs. XLR outputs feed the PA system, and feature a ground lift switch and transformer isolation to prevent buzz and hum from ground loops. Quarter-inch TRS Monitor outputs are also provided for powered speakers on stage.
Once connected, an A/B switch selects between inputs so the backup source can be quickly activated should the primary playback system fail. A JR-2 remote can also be connected to the Backtrack to change the inputs remotely. When cueing up tracks for playback, a mute switch cuts the feed to the main and monitor outputs, allowing tracks to be silently monitored using a dedicated headphone output. This output features its own level control and input selector switch, so even during live performance, either source can be checked without disturbing the main outputs.
The Backtrack is an ideal switching system for redundant playback devices, where reliability and portability is crucial.
