Sub Woofer buzzing
I need some advice please, my new system comprises of-
Sony KDL-46W2000 LCD
Sony RDR-HXD1065 DVD recorder
Sony STR-DA1200ES AV Receiver
KEF 2005.2 Surround speakers.
Now I have set all the above up the Sub has developed what I can only describe as a loud electrical buzz happening at various times and for varying lengths, it is similair to if you were to plug in the phono whilst powered up and at high volume, I have tweaked all the controls of the unit but this makes no differance.
Even with the input turned right down the noise is quite loud, now unfortunately I have no Manual for the sub as it was purchased second hand, I have all the box's and speaker info but no sub info.
The KEF sub has both a right and left phono in, not a single sub in, I am however feeding it from the single sub out on the DA1200ES into the Right Phono on the sub, is this OK ?.
It feel like it needs earthing or something but there is no ground point on the box, I am not sure if it makes any differance but just in case, my connections are as follows, DVD to LCD= HMDI, SKY Digi box to TV & DVD =both scart, DVD to AMP Digi Coax, and the amp is linked to the LCD Vis S Video.
Any help would be appreciatted as I have tried evrything I know apart from stripping the sub and cleaning the electronics.
Thanks in advance Neil.
