    I help at times with a third-world church that powers its services with a 16kw SDMO generator. No grid power available here during daytime hours, so the generator is the only source we can use.

    Despite new audio gear, there's a distinct buzz in the sound output - enough to be distracting. Thinking it's line noise from the generator.

    Would some sort of line filter or power conditioner be likely to help? Other things to look at? I have an audio file of the buzz, in case it's useful, but don't appear to be able to upload audio clips as attachments on this forum.

    Would prefer to avoid a UPS solution because getting batteries and replacing them regularly is near impossible.

    Can you move the generator farther away from the audio gear? Or, can you move the generator around and see if it affects the audio equipment?

    Generator is large, permanently installed in a special building approx 30 yards from the sound equipment, non-movable.

    How is power ran from the generator to the audio equipment? Is everything thoroughly grounded?
