Question about KLH PSW8100-8 Subwoofer
The RCA, RT2870, home theater in a box came with 1 subwoofer. On the back of the amp it has a single (rca) jack to connect a addional subwoofer other than the one supplied. I have a KLH SW90 powered subwoofer that I have had for awhile, that has a seperate amp. the conection on the back fo it has 2 rca jacks, high level imputs L & R. Then L&R regular speaker wire goes out to the KLH woofer speaker box with 10" speaker. How do I connect the RCA home theater amp , with a single RCA connection out to the KLH amp or power control, with 2 RCA connections high power imput(L&R) so the KLH powered subwoofer will work also? Thanks, Greg

SOURCE: My klh subwoofer has R&L
Yes, you use a subwoofer cable and hook it into the mono rca jack in the back of the sub. or you can use a Y splitter 1 female to 2 males. or if your amp has 2 sub outputs (L&R) then use both. I do believe it's said that if you use the high level input, it's better. I forgot why...
Oh yeah. the difference between the 2 is a high level input allows the currant from the amp to pass through the sub, thus allowing the continuation of wattage to your other speakers.
Low level input is only taking a audio signal from the amp. No power is being sen through the connection.

On the subwoofer's L&R input, you'll see a tiny "mono" next to the Left input. Hook up your receiver's single sub output to this jack and you're all set.
