I got a pioneer 1019 ahk reciever for Christmas. Man is it a great reciever. I wanted to hook up some rear wireless speakers so I bought a pair of JBL wireless 2.4Ghz speakers. The problem is I didn't realize that the transmitter needs a preamp signal and the reciever only has amplified outputs for rear surround. I am not electrically inclined, but it seems that a RCA to wire adapter, while good in theory, would blow the transmitter. Is that right? If I am right in that assumption, is there another way to get a preamp signal from the reciever to be recognized as the rear surround speakers? The speakers work great in zone 2, but I am scared to connect them to the rear speaker output. Thanks!
