Hi everybody, thanks for a really good forum!

I got my PSR2000 some weeks ago, and so far I'm very satisfied, with one exception: The Headphone outs seems to be very noisy. As soon as i plug in the headphones, there is a pretty strong "hiss", and the level is constant, independent of the music volume. That means that even if I turn the volume all the way down, the noise is still the same. I can't hear any noise in the main speakers or in the normal line outs when I use them.

Anybody else experienced this? Would appreciate any suggestion or comments.

Mon,

Because I'm on so late at night, I always use my PSR2000 with headphones. I've never encountered a problem with it at all.

Hi MonSound,
Did you also try the test with a different pair of headphones? If you are still experiencing noise (hiss), then I think you DEFINITELY need to return your keyboard. Your PSR2000 may have a noisy (defective) headphone amp. When I plug my headphones (Sony MDR V6) into my PSR2000 with the volume turned all the way UP, I hear no noise whatsoever. In fact, I think my PSR2000 headphone amp may be quieter than all of my other keyboards. - Scott

Good suggestion Scott !
A pretty important issue is the 'impedance' of the headphones. (almost the same as 'resistance')
Some have 30 Ohms, 60, 120, 200 or even 600 or higher !
The impedance is not an indication for the quality..... just different types.
You could try to find out the best sounding impedance ? (Scott : your impedance ?)

Thanks for all suggestions. I don't know the impendance of my headphones (cant' find the papers, and it's not written on the phones itselves). I've however tried different brands of headphones, and I'm not able to sense any difference, the hiss is still there. Sounds like a defective amp? Funny though, that the hiss level is constant regardless of the volume settings?

I heard a loud hissing noise when I first brought my new keyboard home, but later realized it was only my wife reacting to the purchase.

Actually the headphone outputs are extremely clean.

Well DonM, I'm not married and live by myself, so I doubt if the hiss can come from that source...

Seems like I've got to return it for reparation.

I was so confused as to why I heard a hissing noise before I even plugged my new 2000 in..but thanks to Don, now I know why...lol

The headphone output from my 2000 is very clean too on every pair of headphones I own, so unfortunately, maybe there is a problem with yours Mon. The noise from the wife after she found out about the purchase was not QUITE as clean.

I earlier mentioned that I'd tried different brands of headphones with the same result. Today I tried a cheap old Phillips Headphone, and the hiss was gone! I then borrowed a more expensive Sony, and the same result: No hiss at all, even with the volume turned all the way up! But when I swithced back to my own phones of the brand "db" and "Koss", the hiss was back.

Could it be that the impendance of my headphones was wrong? I noticed that I couldn't get as much volume in the headphones that worked OK as I used to get in my own headphones.

Glad that I discovered this before I returned the keyboard. Now I'll just have to test som new headphones to make sure I got a pair that works...

It is great you found the cause !
As I mentioned before I expected the headphone's impedance to be the reason.
The best choice is high-imp ones (200-600 Ohms)Enjoy your KB !
