I have 2 active PA speakers hooked up to an active 18" woofer. I'm trying to connect a blu ray player to them with HDMI. I purchased a Yamaha with RCA outputs, then got 2 RCA to XLR cables for the job. Sound only works with the radio tuner so I called Yamaha and they told me only analog sources will work. Back to the drawing board. How can I hook this all up?? Receiver is going back to best Buy tomorrow. Do I need a processer or a mixer?
