Hi,

Do you use the Y Adaptor to connect from your subwoofer to your receiver? Does the Y Adaptor improve the sound quality of the subwoofer.

I have a Y Adaptor but not sure if I should use it. I would use it to connect the back of the subwoofer (L/R). Right now, I am only using the "L" to connect the cable.

Thanks for any advice!

If your subwoofer has a dedicated LFE input, run a single RCA-to-RCA connection from your AVR's subwoofer output to the LFE input on your sub.

If your subwoofer doesn't have a dedicated LFE input, you can usually connect to:
- the L or R input on your sub;
or, using a Y-splitter,
- to both inputs.
The owner's manual for your sub will indicate the preferred (or permitted) connection options.

Very good and thanks!

The owner's manual only recommend using the L but was wondering if the sound would improve with the Y Adaptor.

Ooops, I missed that question in your initial post! redface.gif My answer to it is: The adaptor should not have any effect on the quality of the sound.

Sorry for all the unnecessary rambling... smile.gif

According to Rythmik you will get an improvement of a couple of db (?) if you use a Y-adaptor.

Jeff-this is really just the same as turning up the gain knob on the sub or bumping up the trim level in your AVR.

The only improvement you will get with a Y connector is when you are using the auto-on function. The slight increase in input gain will help the sub kick in sooner with out raising the sub output trim level of your AVR.
