Strange noise after amp's off ???

Have you looked to see if there's anybody in there? Safety first!

Sincerely, I remain

Hi. I have a Plinius 8200, which is very similiar. Mine does the same thing. I wouldn't worry about it. Most of the time, I just leave my amp on; it has a stand-by mode and a mute switch, so not much signal is going to the speakers. Have you thought of doing that? I only turn it off when I'll be out of town or if electrical storms are expected in the area (then I also unplug it).

Hope that helps,

Dan

two theories here:

• you’re experiencing “dieseling” that can be corrected with fuel injectors kept very clean;

• when you turn off your system, the sounds from the elevator can once again be heard (see, e.g., nanci griffith, “love at the five and dime.”)

My amp has a delayed shut off. I hear a soft sound like that first in the right channel, then the left. For my amp it is normal.

Hi Dan,

Thanks for your suggestion !!!
I almost forgot there's a mute switch that enables the disconnection of the output...

Besides, Plinius suggests to keep it on, accoring to the munual...

Thanks again !!!
