Hello,
I just purchased a 2000 watt Pyle stereo receiver and hooked my speakers to it. About every 2 minutes on the dot it makes a high pitched sound for about 5 to 7 seconds then goes away until the next 2 minutes creep around. I've unhooked the cd player that's hooked up and you can hear the sound still. I've tried unhooking the speakers and trying them 1 by 1 and the sound still persist. I figure it has something to do with the reciever but I dont know what. Thanks for any help anyone can give me. Clint
