Why aren't my subs turning on?

I have a pair of Von Schweikert VS-3/S subs. Auto-on appears to be the only option, but they do not turn on unless I manually turn them off and then on? They are being fed from the line level (called LFE) outputs of an SMS-1. One to each sub. Both were purchased used from diff owners; hard to believe that they both are independently defective in the same way. They both play when I run the auto-eq frequency sweep. I am sending same question to VS, but your thoughts would help. TIA.

You probably have to leave the power off/on switch in the ON position at all times in order for that feature to work.

They will turn off 15 minutes or so after you stop playing music. Once you start playing music again (as long as the switch is ON) they should turn on and begin playing. That's how most subs with auto-off/on usually work.

SW,

Do you have the manual that came with the sub, because it sounds like it may be a problem of not having your settings correct.

When you are playing music you have a stereo line-level source hooked up to the line-level stereo RCA inputs and the switch is set to "Auto-On" with the Red LED (not "stand-by"). Also you have the crossover switch in the position to use the sub's internal crossover and not an external crossover, correct?

Those are my best ideas to check without having the manual for reference...
