To hot or not ???????????


Hello everyone took a gamble and purchased a Trous AVR20 also had a dedicated 20 amp line installed for it my question is my amp is NAD M25 it dosent really say anyware that i can find if it can soak up 20 amps of juice? it gets quite a bit hotter than when i had it pluged into the wall but the amp & sub  and tv really like the full and stable 120 volts just dont want to hurt the amp.Thanx

OH, yeah, plugged into a balanced transformer the meter I recommended will show ~ 60 N-E, that's fine

Hey,

The only reason your amp has of being "hotter" is if the voltage is significantly higher.

I see the AVR 20 has built in voltage regulation. It’s worth examining the voltage at your wall. It shouldn’t be that low. If you find it significantly under 115V, or the neutral to ground elevated over 2V you should call an electrician. If you don’t have a voltage meter, or are uncomfortable probing your wall sockets I recommend this one, for $20 it’s perfectly safe and measures everything at once:

 

Also, measure the voltage at the wall WITH the AVR in place. If it’s causing a large sag it is, again, worth discussing with an electrician. I love voltage regulators, and use one, but they work by drawing more current. That can make existing upstream problems worse. 

 

Best,
