Connecting the outputs
The Backtrack has two stereo outputs: the main XLR outs and the Monitor
¼” TRS outputs. We recommend using the XLR outputs to feed a pair of
line inputs on the PA system, as they feature transformer isolation to help
eliminate the possibility of encountering hum or buzz from ground loops.
A ground lift is also provided on the XLR outputs to further reduce noise
should you encounter a ground loop.
The 1/4” TRS monitor outputs allow you to feed a set of powered speakers
on stage to listen locally to the Backtrack outputs.
Headphone output
The Backtrack features a headphone
output to allow you to test your primary
and backup playback systems. This
is equipped with a level control and
CUE SELECT switch which will choose
whether the headphones monitor
input A or B. Note that this switch will
not affect the main or monitor outputs
of the Backtrack, so you can use the
headphones to ensure both sets of
backing tracks are playing back in time
and at the same volume.
