Confused by my Woofer! (sub)
Discussion
My new Jamo speaker system arrived yesterday. It's a 5.1 with a Sub.
Wiring it up has left me a bit confused!
My Amp (Yamaha 459) has a sub woofer audio-out jack. Easy so far!
The Jamo speaker set came with a single audio cable, however, when you look at the back of the sub-woofer (which has a built in amp) it has both left and right audio jack connections. So I'm left with either the fact that I should have some kind of splitter to separate the single sub output to left and right or do I simply connect to left or right based on what side of the room the sub is on?
The less than clear Jamo instructions are here: www.jamo.com/Admin/Public/DWSDownload.aspx?File=Files%2fFiler%2fownermanuals%2fSpeakers%2fSubwooferline%2f18-10-05_SUB_200_OM.pdf
HELP!

You can run a spliiter from the single channel into both feeds on the sub or just a single feed to one channel. It doesn't matter as subs are not stereo anyway. Has the sub got extra speaker outputs on it? That will be why you need two signals to it. If you're not soing it then one signal is fine. In my experience anyhoo.
The Jamo Sub you have has two ways of driving it.
The first is via a phono cable which will provide a dedicated low frequency feed to the sub box with it will amplify its self.
The second is it being feed with a speaker level, Left and Right feed, from which is will filter out the high and mid frequencies, leaving the low ones which it will again amplify.
Unusually there would normally be a 'out' set of speaker terminals to be able to go on and feed a set of full range speakers. But this doesnt seem to be the case with the Jamo.
Personally you shoudl find the Yamaha amp has a line level out for the sub and I would use that one and just chose either the left of right input, it shouldn't make any difference to the noise it generates.If you are still stuck, we are Jamo distributors so we should be able to find out more if you need it.
Interestingly some people and manufacturers are moving to a 5.2 type system with left and right subs, hence the reason for the left and right inputs on your Jamo sub. This is a bit weird to me as the human ear can not actually determing when bass frequencies are coming from.

Thanks very much for the explanation. It's all plugged in and working nicely now.
