RD 800 : Weird high frequency sound on key D5

Post by Homerun »

Hello,

I just bought new RD-800 for 5 days now. Kind of happy with overall on my first time purchasing a keyboard. The piano sound is great but the only thing that bug me playing is the weird high frequency around 8khz when I press key D5 using "0001 Concert Grand".

Is this a normal characteristic for this piano?

Thanks for your input!
