need help with getting sub to function!

Hi


I am now at my wits end trying to get my sub to work since the addition of my new Panansonic ES10 dvd recorder.
I cant get the sub to work with any dvd or audio cd through the amp (Sherwood RVD 6095RDS)

When i switch subwoofer (Mordant Short MSW20) on it powers up fine and still buzzes which has done for a long time, but i cant get any output from it no matter what sound setting i try, i have toggled with my speaker settings on amp and set all my speakers to the 'SMALL' setting but the amp wont let me toggle the sub setting to on, no matter what! I have still got the manual for this amp, and is says through speaker settings you can toggle sub on and off through the speaker setting button, it wont let me do this.

I have even took my sub to local electrical repair shop, and they have tested it A1-it works fine other then buzzing noise which i can put up with.

I have checked and re-checked wiring but have changed nothing since it worked fine with my old Pioneer DVD 515 player. I have a quality RCA phono lead going from PRE-OUT sub conecter on my amp to LINE INPUT connecter on my sub.

could the sub channel on amp have blown??

i have never really hammered the sub as its very powerful probably too much so for my small lounge, and have never really had need to unplug it from amp

anyone any ideas???

Can you provide a link to the following?

Sub

Receiver

By the sound of things, something is not connected correctly. Sub should not be "buzzing".

ok...how stupid do i feel!

i had another crack at speaker setting on amp, i maanged to change speakers to small, press memo button and hey presto the sub setting is no on!!

So sub works, but still a decent buzzing sound, it has done that for years..

i have checked all connections and cant see anything a miss, but i am no expert!
