Hi,
finally I measured the power consumption for my XMC-1.
The results are really bad ...
Low Power standby:
Powerconsumption ~3W and that’s totally fine for me, but the start up time is up to 30sec from low power standby (Win 8.1 is faster ... come on ...).
Second point is … there is no way to activate the XMC-1 (or anyone tried wake on lan?) through network in low power standby mode. And so you can’ t turn on music from another place / room.
It’s important for me because I have no speakers in my office and sometime I like to hear some (backround) music from the speakers in my living room while I am working …
Video Remains On standby:
I measured ~30W in this „standby“ mode.
Without standby mode and not Video or Audio playback the power consumption is ~31W.
Very confusing ... only 1W? What are theses guys doing here? Just turn off the display?
And of course: IT IS THE DISPLAY! Turn off the display in the XMC-1 settings and press the standby button => nothing happens on your power meter ...
So what you are doing is just turn off the display and block input and call it standby. Right? Really? That is ridiculous ...
Solutions:
1. Speed up booting from "low power" standby to <10sec and add some kind of wake on lan
2. Improve "Video Remains On" mode to <10W
My Marantz AV7701 takes only ~3W and can be turned on through network ...

I don't have your needs. I keep mine in low power mode and have no problem waiting the 30 seconds on start-up.

do a few seconds really mater , in medical instances I can see it but audio ?. now watts matter and 3w standby maybe can be improved.

I don't think they can speed up the boot time, but they might be able to reduce the power consumption in standby mode. Is the concern cost associated with the power consumption in standby? Just curious...

Ok then everything is fine ... Not to disparage your concerns and maybe this can be addressed. In the meantime for your needs as outlined, I would just use it in the 30w mode for now. How much does your power company charge per kilowatt hour? It's money, but it may not be as big as you think. There are several on-line energy consumption calculators. here is just one I pulled up: www.rapidtables.com/calc/electric/energy-cost-calculator.htmAgain, I get where you are coming from and it's a good question to ask if it's possible to reduce energy consumption in the XMC-1 |

In germany we have to pay ~0,29€ each kWh (~0,32$ / ~85$ over the year with 30W 24/7 standby), but I don't care too much about the money. It's just NOT right to do things this way! 5 years development ... I can't believe it.  |

30 watts is about the same amount of power as an incandescent porch light bulb. If you want to make up the difference, find one incandescent bulb somewhere and replace it with an LED bulb... When the XMC-1 is in "high-power standby" it is able to continue to pass video, and to "wake up" very quickly, because a lot of the circuitry actually remains "awake". The only way to drastically reduce power consumption is to turn that circuitry off - in which case we can't pass video when we're in standby, and the XMC-1 needs to do a full boot up when you turn it back on (which is the other Standby mode). Since this is inherent in the design of the XMC-1, it is unlikely to change. Adding a "hibernation" mode like some computers have would add a huge amount of complexity, and still wouldn't get you video when the XMC-1 was asleep, so I don't see much chance that it will ever happen. Besides which, as I said before, 30 watts really isn't a significant amount of power "in the big picture"; your stove almost certainly uses more power in two hours than the XMC-1 does all week. If you really can't bear the power consumption, but still insist of having video while your XMC-1 is off, then you can get an external HDMI switch that uses little or no power. After all, we do let you CHOOSE which standby mode you want to use on your XMC-1 (and we even default to the cheaper alternative). Ok then everything is fine ...

Keith, just curious... why the need to pass video in standby? For zone 2 purposes with zone 1 being in standby?

My other family members (especially my 90 year old mother) like to use the Video on Standby so they can watch tv without using the home theater system.
Regards,
Steve

The reason for "video on standby" is that some people have a situation where they want to be able to "run the TV while the big stereo is off". A lot of folks do this so the wife and kids can watch TV without having to figure out how to operate the XMC-1, or so they can turn on just the TV - perhaps to watch the news - at times when they aren't especially inclined to turn on their main stereo system and aren't especially worried about sound quality. (It's the equivalent of having a small TV set on the kitchen counter for when you don't want to turn the big set on.) With HDMI, it isn't trivial to pass the video signal when the circuitry is off (it's not "just a wire that you can drop through a relay"). The way the XMC-1 is designed, if you want it to pass video, then the majority of the circuitry must be ON; that's just the way it is. The fact that, as long as the circuitry remains on, you also don't have to wait for it to boot up, is just an added benefit. I'm afraid compartmentalizing the functionality of the XMC-1 in such a way as to absolutely minimize power consumption simply wasn't a priority - much as most laptop computers which run on batteries have "power conservation" modes, but most desktop units do not, and most table lamps lack the ability to automatically turn off when you leave the room (although a few do). Please note that, in its default mode, the XMC-1 uses very little power (but you don't get those extra features)... so it's up to the user whether they consider those extras worth the little bit of extra power the XMC-1 consumes when configured that way. Keith, just curious... why the need to pass video in standby? For zone 2 purposes with zone 1 being in standby? |

It's still awake and the XMC-1 just turns on the OLED Display and release your "block Input function". I can't measure any difference between "high-power standby" and "idle without OLED Display". My usecase is all about network access in standby mode ... If the videopassthrough needs so much power, maybe it is possible to add another standby mode with network access, fast boot and low power consumption (without videopassthrough)? |
