Mordaunt Short MS 309i subwoofer setup problem

[admin_exported]

Hi

I just bought a second hand MS 309i subwoofer on eBay which supposedly worked fine. Tried to set it up today and I'm not getting any sound out of it. My amp shows that there is a subwoofer there on the front display and I've tried the manual setup, but still no sound. I've tried the test tone and no sound. I've followed all the instructions I can find online for it and still no joy. It powers up OK. There is a red light at the back which goes green when I turn the power on, and a blue light at the front. I'm wondering if there is something I'm not doing. I had 5 surround speakers running off the amp beforehand but just wanted to add a sub. Can anyone help, I'm at my wit's end.

Thanks

Andrew

Thanks for the link but, that's what I've been using to set up the subwoofer, along with my amp instructions. I think its bust!!
