[thedude2011]

i guys i have just brought my self a yamaha DSP-AX761 and a set of kef KHT-2005.2 and i got a big sub with that ....my question is.... because this is my first set up i have ever had i dont know much about this stuff .....on the back of my sub there are 2 inputs and 2 outputs (Red Line in Right) and (white line in left) - (red high pass output right) and (white high pass output left) and on the amp there is 1 black Sub out ....and the lead they sold me in store for 40 poudns is only 1-1 not 1-2 when i rang them up they told me its fine and i only need to plug this into the red input .... the sub works but i do not know if its working to its full because i have never had a system like this, can any of you guys please tell me if this is ok or if i need a diffrent lead or they have sold me the wrong gear thanks regards anthony

And 1 other thing what are the high pass outputs for thanks !!

Aside from the fact that the lead seems a bit expensive, they're quite right. You do only need a single lead to the sub.

The L&R inputs are for the stereo boys who dont have dedicated subwoofer outputs. Even then, the first thing that happens inside the sub is that the stereo signal is summed into a mono one. The sub's amp is mono as is the driver, so it wouldn't matter if you plugged the sub into the white input either, you'll get the same sound out.

BTW, quick advice. In the receivers menus, set the speakers to size 'Small' and the crossover to 100Hz. Turn the subs crossover up to maximum (or defeat if it has one) and adjust the 'Gain' on the sub to taste. That should get you started.

I wish someone had given me advice like that when I bought my first sub many moons ago. That must be a potential sticky with slight alterations to the crossover values for differing speakers methinks

Have you read the stickies at the top?

<EDIT> I take it back, there is nothing that straight forward in the stickies.

Yes, you buy a '2 female RCA phono into single male RCA phono' adaptor. Cost about £3 from all good audio dealers and a few crap ones too.

The question is, why? What are you thinking?

I was just wondering thats all but thanks guys 1 other thing is i have got 2 spare speakers off my old all in 1 its a panasonic 1 i was thinking about conecting them as left and right surround back ...do you think this will spoil the sound of the kefs tho and i dont want to plug them in and blow them up lol

 

[HiFiRuss71]

They'd probably be OK, but it might be an idea just to run them up as fronts with a 120Hz or higher crossover (to protect them) to see if they go loud enough or sound good enough.

That said, not much happens through the surround backs anyway.
