Why aren't my subs turning on?

I will look for the nanual. I have the L and R pre-amp output (not stereo, the SMS-1 does not output stereo) going to the SMS-1 which IS an external x-over, so I have the internal crossover OFF. The switch is set to Auto-on with the red LED lit (which is stand-by, I think). It goes to green if I turn it off and on manually, and seems to play correctly after I do that. I turned the SMS-1 output (called volume) up to about 60% and still did not get it to turn on when the CD starts up, but it will come on when cycled off and then back to auto-on.

What happens if you set the SMS-1 output to 100%?

I've downloaded the manual and the subs are set up (at least I think they are) the way its recommended. Pre-amp level outputs to SMS-1, equalized output of SMS-1 to sub (there are three equalized (aka LFE) outputs to use so you can run 3 mono subs at once if you desire. No way to run stereo subs without 2 SMS-1s (I asked Velodyne). I will try the 100% output on the SMS-1 and turn the sub volume way down and see what happens.

OK, color me red!!! I just went back to swap right for left at the sub input in case it made any difference, picked up the sub end of the i/e and the other end was dangling loose!! I guess they won't work if they are not connected. Problem solved. Thanks to all who made an effort to assist one dumb-a$$ audiofool. Happy holidays, all.

First step of troubleshooting tree for many electronics issues: "Is it plugged in?".

Glad you got it going and don't have a sub issue......

Enjoy,
