Went on an interesting service call today. HUGE house with an expansive Crestron system (controlling a bunch of TV's, whole home SWAMP distributed audio, and HVAC) that seems to crash about once a week and need to have its power cycled to work. My predecessor had been to the site a dozen times and had gone through the coding with a fine toothed comb and all seemed to be well. At one point one of the SWAMP units had been RMA'd as have a few of the TV's. This left me wanting to check the power situation as soon as I arrived as the home is in a very rural location.
Sure enough at the wall I get a reading of 130 vac. I also get the same reading out of the Surge X (provided by the lead A/V contractor - we were just hired to program and consult on the control system) unit that the Crestron is plugged into. Looking at the spec sheet for the Surge X SurgeX - Products - SX1115R, RT, RL Surge Protector / Power Conditioners it seems that it only trips at closer to 145 vac. I'm thinking that the Crestron probably wants more stable power and for the time being had them plug it into a spare UPC they had laying around, just to see if things run smoothly this week. If that fixes it we can get a nice rack-mount UPS to cover the control system HOWEVER my question then becomes what do I do about the SWAMP amps. In any other circumstance I wouldn't even dream about using a UPS on an amplifier but would a really beefy one (or two) be my only option in a case like this? What about a voltage regulator instead FurmanSound.com - Pro A/V Product - P-2400 AR Some other type of product I'm overlooking?
Oh I should add that there are a total of two Swamp amp/control units each drawing 12 amps at 120v.
