2.1/2.0 Speaker Systems (READ ONLY ARCHIVE)

Hi all,

I just got this new set of speakers, the Logitech Z2300 and I'm not sure about the quality of the product.

My problem is that when I turn the power of the speakers on (without my PC running), I can hear a very suttle buzz coming out from both speakers. It's not loud, I have to put my ear close to the speaker to hear it so I was wondering if all of you had this issue. I hear it even if I turn the volume all the way down. If I turn the potientiometer all the way up, the buzz is even higher and much more noticable (it starts beeing higher at 75% of the potentiometer).

Now, if I turn my PC on and I put 100% volume within Vista (so max output from OS), the buzz becomes much, much higher. I though this could be my on chip Realtek Sound Card so I bought the Creative X-FI Fatality Titanium which reduced the output noise but not that much.

Do you guys have the same problem? What would you suggest I do?

Hello Jtheoof, Welcome to Logitech's online forums.

In your case, try a Product swap from your retailer. Depending on which batch you have at the point of Manufacturing, (see manufacture stamp on inside flap of the box) the odd ones might be faulty. The buzz is amplified when the volume is turned up (normal behaviour).

In my case, the buzz comes from the faulty internal power supply.

Thanks for your answer,

Can you explain what you mean when you say that it is the normal behaviour that the buzz is amplified when the volume is turned up?

So every Z-2300 has this "issue"?

When I turned my computer off yesterday night, after I plugged it on the Creative SoundBlaster X-FI Titanium Fatal1ty, I did not hear the increase in the buzz when the volume was max. It seems it only appears when Windows runs. Both with the Realtek chipset and Creative sound card.

You think I should RMA my speaker set? (I bought it with Amazon).

The Buzz is amplified to the speakers when the volume is turned up, hence called amplification - Almost every speaker system produced not just logitech (If I'm not mistaken) has this issue.

Refer to the site below for speaker info about hum, buzz, hiss, pop, clicks & Stutter (Linking doesn't work)

I don't know a thing about external sound cards....

If your speaker system is within 2 years then you could give RMA a call. But call Logitech's Customer technician first.

Thanks Insomialife for your help.

As I read on the link you gave me, it seems the reason I hear the buzz louder when I set the potientiometer of the Z-2300 to 100% is because the Realtek chipset is very bad compare to the SoundBlaster X-FI.

I will call a Logitech technician to make sure the light buzz I hear when I get my ear very close to the speakers is normal.

Thanks again.

Good luck with your system. The Z-2300 is an excellent product even after 2 years. Mine still works like new.
