Okay, I'm stuck. I can't get the sub to play music again, and I never got the satellites to play when connected to the sub/amp. I know that the satellite speakers work, since they play fine when connected to my Gainclone.
When I connect the outputs from my preamp to the subwoofer, I don't get any sound. This is puzzling since there was output on the woofer previously.
That signal chain is:
CD Player-->Passive Preamp-->Nakamichi sub/amp.
Now, I'm using a passive pre, so...are the Nakamichi amp boards expecting/needing higher voltage inputs than what my setup is using to be able to play? I'm way out of my depth here.
The receiver I was trying to use isn't working either, so it's out of the picture.
