Hello,

I just bought Meridian D2500 sub-woofer, while the previous owner says it works.
I have connected the sub to my Denon AVR-987 via pre sub out. The sub would not get a test tone. There is power going to sub and when I turn it on I can hear a thump.

Please help me to resolve the issue.

Thanks
