I had a JBL E250P malfunction so bought the Polk PSW 505 based on reviews for this range. I am an old rocker so I have a Yamaha RX-797 (I bought mainly for the bass , treble and loudness controls.) The manual does not say if the sub out is full range but assume it is as it is not a digital receiver. I was always taught to hook these up to the left RCA input but the manual with the 505 says you need left and right connections. I can't see how using a "Y" adapter would do any good as it would send the same signal twice. I assume that I should just hook up the sub out to the left non LFE input??
Thanks of any input
