So I was watching a movie a couple of nights ago at a very modest level, then all of a sudden my RSX 1550 turned off. My 1550 was the only unit to turn off, everything else stayed on. I'm thinking it was a voltage dip that triggered the unit to turn off? Two questions. Does this sound correct? How many times can this happen before it starts to negatively affect the unit? I'm not looking for a solid number, more like it can continue to happen with no problem or it will cause a problem eventually. I'm assuming the unit has some type of a kill switch to aid in situations like this.

It's possible that a voltage sag could cause the Rotel to power off, although none of your other devices were affected. Voltage sags can cause harm to electronic equipment, particularly those with sensitive microprocessors, so if in fact this occurrence is attributable to voltage sags, it is not something I would be comfortable with on an ongoing basis.
But it is hard to say if it is a voltage sag causing the power off, or some other anomaly with the Rotel unit. A multimeter that has Min/Max voltage capability can be useful to troubleshoot if this might be the problem. The easiest (and safest) type would be one of the plug-in meters designed to measure this and other power usage parameters.
If it's worth it to you, the Watts up? series of plug-in meters do record Min/Max voltages and cost ~ $100 for the basic unit, or ~ $130 for the PRO unit which can also download the data to a PC via USB so that you can see how the power might fluctuate over the course of a day. https://www.wattsupmeters.com/secure...wai=511&comp=4
Unfortunately some of the less costly power usage meters, like the popular Kill A Watt, do not have a Min/Max function.

Thanks for the reply. Funny you recommended that, I just ordered one yesterday. I figured I should start at the root, and then go from there.Comment

Oh, cool! When you get a chance, please give us some feedback on your measured/monitored power situation as well as on the Watts up? meter itself. I have a Kill A Watt P4400 just to measure current draw and power consumption.

Will do. :TComment

This is aimed at those among you who have not worked with high voltage, but are thinking about projects like tube amps and such. ALWAYS HAVE SOMEONE WHO KNOWS WHAT THEY ARE DOING WATCH OVER YOU. Never ever start out on this alone. I'd heard this from others before on another DIY site but never had an... -
Hi there everyone! I recently had my stuff moved out of storage from another province to the province I moved to three years ago, it's so nice to have my stereo back. I've got a quick question about my power conditioner. At my old place the power coming in was pretty stable at 120V, every once in a... -
anybody having trouble with the 1098 volume just shutting off after about 15 min. trying to re install ver 2.1.2 to see if it helps. -
Does anyone know who makes analog power meters, like the ones Macintosh uses, but smaller? I like the look, some fallout from the demo

In another thread I asked a question about my houshold voltage being in the 115v-118v range and if it was normal. Household . I was wondering would my setup benefit from a Monster Voltage Stabilizer. Everything in my setup except my amp states Power requirements of 120v.
