Hi all, i'm new in this forum and i'm from Italy (so i hope you will forgive me for my bad english). i bought the PX5S a few weeks ago, and i'm going mad whit a strange noise in the back when i hear myself whit the phones and when i'm recording: 1 ) just only plugging the phones in the appropriate slot i start to hear a hiss, something like a blow (SSSSSS) indipendent from the master volume. i'm using a pair of AKG K66 (32 ohm) but also with some other phones from a couple of friends i have the same problem: plug the phones in ---> ssssssss i hear the hiss. only with the high impedence ones i don't hear anything, but i think it's only because i hear a lower sound volume. 2) now, when i record my audio tracks in ableton live going into a focusrite scarlett 2i2 with jack-jack reference cables (all connected to my macmini 2012) i have something like the same problem: i see the audio wave dirty also in the parts of silence... and when i normalize it i hear it clearly: sssss in a first time i thought it was a problem of my house electric system but i have the same issue if i go with batteries, disconnecting my piano from the electric circuit. so, is there some way to fix the problem or have i to take the px5s back to the shop and ask them for a checkup? thanks to all who will answer! Enrico
