For anyone who owns the PSB SubSeries 100:


Do you notice any consistent hissing sound even under the following conditions:

-Relatively quiet room, if quiet enough, audible more than 2 meters away.

-All sound signal inputs disconnected, leaving only power plug connected, and LED is green (non-stand-by)

-Volume turned down to 0,  or any volume, it's the same.

(Safe to say  that this hiss is caused by power alone, nothing to do with the sound source or the sound (LFE) input.)


Or is your PSB SubSeries 100 dead quiet plugging in only power cable and in green LED?


Appreciate any input, thanks!


I am currently in contact with PSB's technician regarding this issue I am having.
