Technics SX PR604 digital piano - How to suppress the hiss sound?
by James
When I switch on my piano, there is a low hiss sound, not loud enough to interfere in my playing but it does bother me. You cannot hear I play the piano, not even when I hear it from headphones or if I plug it into separate powered amplifier. Its just when you switch on and don't play anything or when you are looking at the sheet trying to focus on what’s written that it really bothers me. Can this be fixed anyway? How much would it cost to repair it on my Technics SX PR604 digital piano?
