OVERVIEW

The Backtrack is a two channel redundant switcher used for live
performances where backing tracks are being utilized. Should the
primary playback device fail, the Backtrack allows you to quickly and
seamlessly switch over to a backup device; this is done using a switch on
the Backtrack itself, or using an optional remote footswitch.

The primary and backup playback devices can be connected to the
Backtrack via ¼” TRS connectors or 3.5mm jacks that allow easy
connection to the outputs of smartphones, laptops and tablets. Balanced
and transformer isolated XLR outputs are provided to feed the backing
tracks to the PA system with a ground lift to eliminate hum and buzz from
ground loops. The outputs can also be monitored with a pair of powered
speakers by utilizing the ¼” TRS monitor outputs. To silently test each

playback source, a headphone ampli er is built into the Backtrack, which

includes a separate level control and the ability to listen to input A or B
without affecting the output to the PA.
