D sub pin assignments Logitech z640 plate amplifier

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.

Yes but it depends on how they plug into the back of the sub as to how hard I will be

1.Cut the appropriate size hole.
2. be sure the amp supports your sub with the proper impedance.
3.wire the plate to the sub
4. apply sealant to the plate where it touches the box. sealant, not glue.
5. connect you plate amp to power socket.
6. setup your preferences with the knobs on the plate amp, sub sonic, LPF, boost, gain etc.
check for leaks and fix them.

It is hard to say. The sub-woofer has its own amplifier, although it is supplied the sound data from the main amplifier. It could have a problem with the battery power circuit (Sub-Woofer Amplifier Connector Pin 6, LIGHT GREEN/VIOLET) or it could have a problem with the GROUND circuit (Pin 2, BLACK/LIGHT GREEN) Or it could possibly not be receiving the signal from the main amplifier (Pin 7, BROWN/ORANGE "+"), (Pin 8, RED/BLACK "-"). Or it could be that either the sub-woofer speaker is blown, or the sub-woofer amplifier is defective.
There is also a "High Audio Mute" circuit that connects between the main amplifier and the sub-woofer amplifier.

Here is a link to the manual for your surrond sound speakers.

Hope it helps.

Do you mean "Logitech" Z640?

I'd lurk on eBay or other auction sites and see if one becomes available.

Take a clue from that non-standard system cable between the electronics and the sub. It powers the sub's amplifiers and carries signals. Wanna take a chance on the pin-assignments being consistent across all product lines?

you shouldnt have any problems with that amp pushin those speakers it all compatable

what piece are you seeking? the amplifier or module to convert to your TV? to make this work, you'll need to inform us of the computer make/model and o/s, and the TV that you're looking to plug into.
