The amplifier is a uP (micropower) chip that shuts down to just several
microAmps when not in use. It's designed for portable systems where
energy conservation is imperitave.
It hasn't officialy been released yet though, and I await it's release,
so I can see if it can be adapted to the SPinTerface Speaker cart. The
cart uses tons of power, even when no sound is made.
Hope I cleared that up for you
