I am hoping that someone with experience or knowledge might know the answer to this question, or that perhaps @Andrew or @James might have a ready answer. I was discussing with my dealer yesterday my various AC power improvement plans and my exploration of running certain components on battery power so that, no matter what happens to my AC mains, these components would never lose power. On my short list for this group are:
- Vivaldi Clock
- Cybershaft Clock
- Legacy Audio Wavelet Processor
[The Wavelet is a non-issue, and is mostly a matter of convenience. When it loses power, and power is then restored, it does not power itself back up. And it resets its gain level much lower.]
When I mentioned this to my dealer, he advised me that he “had heard that you don’t get good results with the Clock using battery backup.” Now, I like my dealer a lot, but in the past, whenever I heard something like this, it was usually French for “we don’t sell that solution.” OTOH, he could be absolutely correct. So, I thought I would ask the experts here.
I have several UPS devices by CyberPower and TrippLite for our key computers and servers, but I learned that these are line interactive devices, good enough for computers that are designed for the several millisecond switch over, but probably not ideal for audio equipment. I came to the conclusion that the best type would be a double conversion type. This type of device does not have to switch to battery when AC power is lost, because it is already running on battery. A number of companies make such devices; the folks at Torus Power recommended Eaton, because they are very quiet and are used in studios around the world. On their advice, I settled on an Eaton 9PX700RT (these three items don’t require a lot of current; even at just 700VA, this is probably overkill)
So, this raises two questions:
- Will powering the Vivaldi Clock on a UPS like the Eaton present any unusual risk to the Clock? I’m not looking for guarantees or warranties, just guidance.
- Should I expect this to impair the Clock’s sound quality?
