Hello, I got my first OAW3 for my SVS sub, hooked to my Onkyo receiver and it appears to work fine. So I ordered another transmitter and 2 receivers to go from my iTunes on my mac to both of my Onkyo receivers. It constantly cuts out then it will play for awhile 10-15 minutes then cut out for a minute sputtering sound. Very annoying and I have adjusted the transmitter and the receivers to no avail. I am using a different channel than the one for the sub. Has anyone else had this problem? The transmitter is only about 20-25 feet from the 1st receiver, though it is in a hidden equipment room, a french door and a wall away. Did I get a bad unit? Help this sooo frustrating I feel like crawling under to hard wire it. Thank you in advance, Dan
