Hi,

Before i get started, i know this problem isnt related to Dell, but i've seen plenty of peeps posting here that have the same speakers in their sig's, and maybe someone might have some advice/help, thx.

Well, I recently bought some Logitech Z680 speakers, as an upgrade
from my old Z640's. The sound/power of the Z680 speakers is
really awesome, but i get this constant white noise (hiss)
from the speakers. The loudest hissing noise coming from
the centre speaker. At lower volumes the hiss from the
centre speaker can still be heard (although the hiss from
the remaining satellite speakers is drowned out even at
very low volumes).

At first it didnt bother me, but after a few hours at my pc
it starts becoming unbearable listening to the high pitched
hissing. When not playing music or gaming, i just cant keep
the speakers on.

I have read on the logitech support site, that most high
powered speakers emit a slight hiss/noise which can only be
heard when your ear is right next to (or 'very close' to)
the speaker. Well, the closest speaker is about a metre
away from my ear, and the noise can still be heard
(clearly).

I have an Audigy2 sound card (retail version) so i dont think that it could
be causing the problem. My old Z640's had not one bit of
inteference or noise/hissing. I am using the analog inputs
that came with the Z680's, would a digital input solve the
hissing problem?

Please could you give me some advice on what the problem
is? This constant hiss/noise is driving me mad.


Thanks for any help.
