pure sine wave inverter back up good for home theater system?

[subratac]

Hi, I am Subrata from Gurgaon. Excited to join hifivision.

Need guidance on following...

my back up need is 1200 watt. Denon AV Receiver & Cambridge Audio Stereo Amplifier.

Can I opt for pure sine wave inverter instead of line interactive UPS?

Or online UPS is a must?

Grateful if veterans can advise

pure sinewave will still have fluctuations. You can see how our lights bulbs etc. fluctuate on inverter, not a good idea

IMO power back up is not needed for audio gears. Good voltage stabiliser, isolation transformer with a high quality surge protector is the best approach. I use a servo stab and isolation transformer with surge protector and a DIY emi/rf filter. Had one PA board and speaker tweeter failure through out my Audio journey.

On line ups is must especially for projector.

I mentioned for audio gears. No idea on projectors

Depends on where you are really. Bombay generally gets clean power and you don’t really need an online inverter. Here in Bangalore we have pretty lousy power so it’s essential. Tried the stabiliser with spike buster combo with the TV and my older system and ran through 2 of them (stabilisers - thankfully). So when we upgraded our stereo and went to a top end TV, just went with the online inverter for peace of mind. It’s worked so far, touchwood. I personally think it’s worth it these days regardless of where you are given how many gizmos one has in any modern household. And if in an apartment building, the generator kicking in doesn’t help either.

My two cents.
