Too much load on the line is causing a voltage drop, If it only occurs
on that one circuit then your loading it greater than the line can
handle, which makes sense since it only occurs during the few cycles
that the motor is starting (which is a muuuuch greater load). If you
own, run a dedicated feed for your stereo/myth, if not, plug it in
somewhere else =)
