just out of curiosity,
it is my understanding that pre-amp out on a hu is a dc signal correct?

what I am trying to figure out is when you examen the signal on RCA's, is there a signal on the center pin and on the shielding? if yes, then why do soo many people recommend to ground the shielding to take care of noise instead of installing a transformer in the line?:confused: it is almost like running the negative speaker wire to ground!?

i do not have an in-depth understanding of the RCA's, but would like to know:D

The signal coming out of the RCA outs is an AC signal.

There is only signal on the inner pin. The shieding is simply a ground.
