Hello to everyone,

It's been a while since I had my 9000Pro, but I've noticed quite recently that my keyboard is actually "hissing" when I put the volume right up. Of course every electronic musical device creates a fair bit of noise, (I believe it's called signal to noise-ratio) but my 9000Pro is very noisy.

So if there are any users of PSR9000, or 9000Pro, could you please check if your keyboard makes a significant "hiss" at loud volumes?

I have compared this to a Yamaha Motif and the Motif is very quiet. (So much for the Yamaha's "Pro" ). Even on headphones you can hear this "hissing". Not buzzing noise, just hissing.

Could someone please help me out?

Hi: Puzk
I just tried my 9000 Pro & there is no "hissing" or any noise,
I used my headphone's & I can't hear any difference from
volume control set at low to full volume.
Complete silence.
The same holds true going thru my PA system, it is very quiet.
I can get some hissing noise if I connect the Pro to my mixer &
turn everything up to max volume, but I think this is normal.
Hope this helps.
Enjoying the 9000 Pro

I had the same problem when I had my PSR 2000, I had the EQ setting just a little bit too loud. I don't know if this helps but its worth a shot

Have you tried different power sources... perhaps it is line noise?.....
t.

Like Jerry wrote, the problem is most likely in the Eq settings: try to reduce the high frequencies (first two cursors on the right).

I get hiss at full volume on my 9000Pro, but it would be impossible to play at this volume.
As an example play your 9000Pro at as loud a setting as you would normally. Now without touching the volume STOP the keyboard and then listen for hiss....its basically inaudible.

Like Jerry and Andrea said, with flat equalization I don´t have any problem, but if the high frequencies level is too high the "hissing" is too strong.

Turn the MIC volume down in 9000Pro mixer.

Thanks for all your comments and help,

Shakil you were right. Thanks,
I just realised that it was my mic volume. And the high eq'ing made even less noise when I put the volume up.

I was getting suspicious of the power supply of the keyboard because sometimes it was making some noise on the keyboard.

Anyway, I would like to comment that if anyone's using the 9000pro or any other PSR that uses a mic input, to put the mic level to zero when you are not using the mic. It makes a significant noise on your keyboard output.

whoops,

I meant to say, flat eq'ing makes less noise in your output.
