I am unable to get an older PSB Alpha Subsonic 1 subwoofer to work on my RX-A820. I have two of these subs and they work fine on older Yamaha receivers. I have tried both without any luck. I believe I am probably missing something really simple. I have connected using the subwoofer 1 out on the RX-A820 and plugged into the R input on the Alpha Subsonic. When I run the manual speaker setup on the receiver I do not hear any test tone when it cycles through to the sub. I know these are older model units but I am hoping someone might offer some advice here. Thank you!
Stupid question: have you turned on the sub output in the RX-A820's settings? I don't know whether it defaults to "off". The AVR will not automatically detect whether a subwoofer is connected.
Thanks Bob, not a stupid question. I did check and it is on. I have the subwoofer set to “use” in the configuration. I am wondering if there is any easy way to determine if there is output from the sub connections or if it may be an internal problem.
