AUTO SENSE
The XDi 1200.6 uses BTLD (Bridge Tied Load Detect) Turn-on circuit
that offers a significant improvement in reliability over previous
designs. Instead of relaying on the music to supply enough signal to
turn the amplifier on. Robert Zeff’s design detects the IC (chip) used
in the vast majority of stock head units and amplifiers.

It is important to note the Auto Sense will not always work. Do to
the hundreds (or thousands) of different OEM system configura-
tions, no single solution can be 100% successful. If your system
does not reliably switch on and off, look for an alternative turn on
source. It is possible to spend many hours trouble shooting an
Auto Sense problem. This is time that could be spend enjoying
your new audio system.
