Question about Yamaha DVX-S120 System
I have positioned the amp below a Digital Satellite receiver. On occasion, about 5 minutes after switching the unit on, a high audible level Air sound comes out of the amp -- only switching off the unit and powering on again removes the interference.
On many occasions high pitch interference is a result of bad wiring and grounding problems. Check to make sure that you followed the manufacturer's instructions concerning grounding and installation of the amp, and if possible try and install it at another location in your house, using other electricity sockets. If the problem is solved by relocating the system, you might be looking at wiring problems (audio equipment can be very sensitive to that), if changing anything in the installation process solved the problem then the problem was probably due to bad grounding and "loose" electricity. Try making the installation as "clean" as possible, avoid tangled wires and stressing a single socket with too many electric appliances. If the problem persists, and you are still under warranty, I suggest contacting your local Yamaha dealer. If you're out of warranty I suggest locating a professional repair person.
