This is really strange! I just got a larger new equipment rack, pulled out everything, set it aside for the night, and reinstaled it the folowing morning. Everything worked fine for an hour or so but on touching one of the Sig 70s I lost all output. I recheck everything to no avail. Thinking that somehow the 70s might have somehow discharged I let them charge overnight. The next morning the red LEDs on the chargers were still lit. That sounded bad. I turned on the 70s but still no sound. I turned them off and now the green LEDs come on. I unhook everything and hook back up. Now I have sound ok. I play music for an hour or so and then shut down. With both power switches off one Sig 70 is still playing and the power LED is on --  even though the power switch is off. Also the green LED on that charger is on! If I toggle that units power switch on and off the only thing that happens is that the charger's green LED is off  with the power switch off and both charger LEDs are off with the power switch on. But the unit plays no matter what. I can't shut it off.  Vinnie -- HELP!!!!!!!

Hi PLMONROE,

Please email me and we'll go from there. 

Thanks,

Vinnie

Thanks Vinnie. Glad to report that everything is back to normal and the Sig 70s are sounding like their old selves -- which is like a million bucks!!!  Just one of those weird things I guess

Hi Paul,

Just blame it on your new equipment rack 

Thanks for the good news,

Static electricity?  It's that time of year for it and I have been having some similar weird things happening with my DAC and/or transport.  Sometimes, when I touch something in the system, it will knock out the right channel.  I shut everything off, wait a minute and turn everything back on and everything is OK again.

That is also what I suspect to have been the culprit.

Hi Gerry E.

Welcome to Audiocircle and the RWA forum.

It is possible that static electricity was the culprit.  ESD (electro-static discharge) voltage can be very high...a few thousand volts is not uncommon! 

This the first that I have heard of a problem that PLMONROE has described (with a Sig 30 or Sig 70).  It is hard to know for sure what was the culprit, but I still suspect it was the equipment rack 

Best regards,

Vinnie

So, did the amps fix themselves?  Inquiring minds want to know... 

I hate things that fix themselves, especially computers and cars

Its more like the problem went away, Jim. I still think the most likely explanation was static electricity. Between the first week of January and the middle of February we had the worst five weeks of winter I have seen in the 36 years we have lived here. Whats more I had been shuffling around the room, which is heavily carpeted, quite a bit just before I touched the equipment and things went bonkers. But if so I am puzzled why things took so long to correct.

Paul,

Yes, ok I buy all that, but I am just really having a hard time wrapping my head around the fact that the unit kept playing when the power switch was turned to the charge position.  There's just no connection between the power source and the amp board at this point and that's what just baffles the hell out of me.

Where do you live, BTW?  We're having our worst winter here and just fell 3 days short of the all-time record for snow on the ground.  They say that on the Colorado Front Range new snow never falls on old snow, but until just this past week it had been doing that at pretty regular intervals since before Christmas.  It also looks like upstate New York is getting pounded too -- I went to college in Rochester and know what a typical upstate/western NY winter is like but my friends who still live in the area say it is about as bad as they have ever seen it.

Glad it's all working for you now though,

Jim

I agree that static electricity would have had no bearing on the unit playing with the switch off (or none that I can see). I toggled the switch back and forth perhaps 75 to 100 times trying to get it to work normally, so perhaps there was a speck of something that had gotten in the contacts that my actions dislodged. Don't know.

 I am in Oklahoma City. It's the Ice Storms that are killers here. However I shouldn't complain I guess. Earlier I spent a few years in Grand Forks, N. Dakota. I arrived there at the end of a February to be greeted by my first "Blue Norther" the next day. It hit at 12:30 and by 5:15 that evening the outside temperature had fallen from +12 degrees F to -42 degree F, and I am talking temperature, NOT wind chill (that must have been minus 60 t0 70)!!! And even that did not set a record low for that date. I never saw it that cold there again. One of our ironic pastimes in the winter was watching the temperature reports from Fairbanks, Alaska -- which were always higher. Jeezzzz.
