I have a KLH SW-90 amp. When I plug in the RCA plugs I don't get any sound to the Satelight speakers. Is this a sub amp? Do I need to hook up the high input wires to make the satelight speakers work?

I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.

If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.

Wrap a wire around the outside Metal of your rca jack in back of your radio and ground the other end of that wire to the back of your radio and the noise goes away

Yes, the 10-120 can use a L & R low level subwoofer input. You can get a short 6" RCA splitter adapter from Radio Shack for a under $10. (1 female input, 2 male outputs) Alternately, just plug the subwoofer output on your receiver to just the low level R channel on the KLH sub.

Low level inputs are designed to take signals directly from an amplifier's "sub out" connections. That way the KLH amplifier will use those signals to produce sound and the volume can be balanced between the main amplifier and the sub amplifier using the sub's volume controls. Depending on your amplifier and sub, that is the best way to connect them. However, be careful running the RCA cables since the low levels are more subject to interference. Keep the runs as short as possible and use high quality shielded cables for the interconnects.

For powered sub :If your receiver has a sub woofer output on female RCA plug, that is the way to go. If no output you will have to get a speaker line to line output converter to then connect to your subwoofer amp input.

Unpowered sub - just hook up across the speaker terminals for each channel making sure that you hook it up in phase.

It's unlikely that you can find a shop to repair it for less than the replacement cost ($75ish for a comparable KLH or Sony sub)

If you're up for doing your own soldering, here's a solution for the same problem with the same amp.

If this helps, please hit the "thumbs up" for me!

hi there
on your CD deck or what ever unit you plugged the RCA wires to needs to be set on subs the radio needs to be set to put sound to your amp.....on your CD player if you press the F/function button a few times it will scroll to SW which is for the subs set this to the on position or if your CD player has a button with SW press it and turn on this feature......if this has been done......check the fuse or fuses on the amp.......if you have done all of the above check the back of the CD unit to make sure you are plugged into sub-woofer RCA or R (rear) RCA ..........sometimes people accidentally put the RCA wires into the aux input RCA,,,,,, double check this.........
hope this helps

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.

Did you try making sure the subwoofer is turned on under the set up menu on the Sony Receiver?

Press Set Up, Press the left or right button above the scroll wheel until you get to SW. It should say SW: ON or SW: OFF. If it says SW: OFF, use the Scroll wheel to scroll right until it says SW: ON. Also, make sure you aren't in 2CH mode, try A.F.D or surround sound.

For Stereo Mode (Front L & R Speaker), you must plug RCA cables (match up red and white) from Output on DVD player to DVD Input on the back of the receiver. Then with speaker wire, run from receiver speaker output (Front Speakers) to designated speaker (make sure + and - match up to both input and output). As for hooking up surround sound, I'm currently trying to figure that one out with just using the L, R and Center. I don' t want wire running all over the place just for rears. Hope this helps
