Just took delivery of a SurroundBar and PSW505. I'm connecting it to an HK AVR330, which I previously used with four LSi7s and another PSW505. The sound from the previous set-up was pristine on all channels. I ran the test tone feature, and I'm not getting any sound from the center or left channels. The others appear to work properly. I've checked the connections, and they're all good. I've also checked the inputs on the AVR by switching the speaker wires, and I get tone then. Is it possible that I have a couple of dead channels on the SurroundBar?
