Trends Audio Ta-10.1 - white noise?

Hi!

Is it normal, that a constant hiss is comming from that amp while not connected to any input source? It can be heard from the tweaters in a very close distance only.

Or are your Ta`s completely silent?

Thanks for your info!

sounds very normal to me. when an amp has an open input connection it sees everything in it's surroundings, including it's own rf pollution at the input. with a input device (i.e. a cd player) connected most of this airborne pollution is drawn away to earth via the output resistance of the input device. If there is no noise with a close connection than there's is absolutely nothing to worry about.
