Yamaha av receiver power protection
i am using my yamaha av receiver using a separate inverter because i have an extra inverter probably a square wave.
is it safe to use it? i dont want to use av receiver to my main supply because of frequent cutoff and fluctuations. and i also dont want to spend money on extra ups. so i am using my extra inverter for avr only.
so square wave inverter can harm av receiver? keeping in mind that av receiver is again going to convert square wave AC to DC.
