Confusion on amp to reciever connection?

Guys,

Hi all, little confusion here, please help.

I have the Denon 1005 speakers which are great, and have recently got a Yamaha rvx100 reciever.

However im confused on how to connect the subwoofer to the reciever

On the back of the sub i have, two red and white sockets which say

Line in L, (White)
Line in R, (Red)

Or High Bass out L (White)
High Bass out R (Red)

This is the red and white connection leads, but on the amp i have one (black) subwoofer connection, do i need a different lead for this?? or do i just connect one of the red/white leads?

Also on back off subwoofer i have a switch for Ground in or out? Which one, please help

Regards

A sub cable has one of these at each end http://www.tvcables.co.uk/cgi-bin/tvcables/PH101.html you should connect to line in L or R it should not make a difference. The grounding switch is to stop hum (earth loop), so if you hear humming from the speaker switch it over.

So i dont need a red n white phone to connect to amp.

I can connect to Line in L or R yeah.

Cant i use the red/white phonos i have,

ie, white to Line in L, then the white to the single black jack on amp as they look the same connector as the subwoofer lead you showed me!


Sorry!

No reason why not but do suggest getting a decent cable that is designed to support low frequencies (A Sub Woofer cable).

The cable i have got is very good quality

So i can basically attach white from Sub to the sub out on the reciever?

Or should it be red from sub to the sub out on reciever?

Sorry new to this!

I take it there isnt such a thing as a special sub lead huh, you can use a good quality red/white phone lead and use say just the white or red section, or am i getting this soooo wrong!

Cheers

Sub out on amp to left line in on sub is the norm, but it doesn't really matter.

A sub cable is basically a normal phono cable, so you could use half of a stereo cable.
"Proper" sub cables tend to have better shielding, to stop the pickup of interference and mains hum. Try your existing cable, and buy a different one if you have problems.
