    I'm putting a small computer in my home theater. I've always put small battery back ups on my computers.
    I was thinking, why don't I have one on my system??
    Is there a reason I shouldn't put a APC UPS or similar model on my system? Any idea how big I would need? I was thinking 1000VA size.
    Any folks using one?
    Thanks
    Tom

    While certainly not necessary, UPSs will filter out spikes and dips in your electrical service, and hell, you can watch the end of a movie if the power goes out! [​IMG]

    Nooooooo! Most UPS's output a squarewave, not a sinewave like the electricity out of the wall. Computers can deal with this becuase of their electronic switching power supply, but it would not be good for audio equipment with it's transformer based power supply. Also, it would most likely degrade your sound.
    It might be ok for your TV, and I have one for my Tivo (which is a computer), but keep it away from the audio equipment.

    I've done it before, and even when power is removed, there is no change in the sound output from the system. No degradation.
    but maybe I just don't have tose "Audiophile ears" that some do...

    ken is right about the squarewave thing, but the better UPS's output a sinwave. check the manufactures specs, they should help you out.
    filtering dips was my primary motive, we get lots of "instant off/on" cycles here in the lightning capital of the world, so brownout protection is a real issue for me.
    (finishing the movie once the power clicks off is a fun side affect.)
    i use an APC smart 1000 on my tv, reciever, and dvd player.
    works wonderfully.

    My UPS was a big 3000 amp unit from APC, so maybe that's why I never noticed a difference in sound/picture quality when it was on.

    Look into an APC Line-R. They make some pretty high voltage ones.
    Essentially, it's a UPS without the battery - or more directly - a line regulator. It can raise low voltages, and lower high ones, just like a UPS from them can. The only difference is that when power goes out, so does the Line-R.
    But - really - you don't expect to run your gear when power goes off, do you? [​IMG]

    No, but we have lots of lightening strikes and 2 second dips are often and it sure is hard on the equipment, at least it sounds hard.
