View Full Version : Duet power consumption and user habits

Search was unsuccessful, so maybe someone can help: What is the power consumption of the Duet receiver on/off (from my experience with squeezebox the difference will probably not be huge). Do people usually power it off? As the receiver isn't really visible - the great WAF advantage in a non infrared environment ! - it is easy to forget to switch it off. Maybe an automatic sleep mode would be useful.

The other item is the controller. Is it recommended to turn it off? How much energy does it use? It takes so long until it powers up again. I guess here again people don't bother to turn it off. Any views?

Lots of info on the SBC power saving modes at http://wiki.slimdevices.com/index.cgi?JivePowerModes

From my memory the SB3 takes around 5W whether idle or playing, slightly less when the screen is dimmed. I imagine the screen is one of the larger power consumers so I'd expect the SBR to take less, maybe 3-4W? Small enough for me not to care about.

Of course turn it off... a glacier is in jeopardy!
5w is like...ooooh so much energy.
Seriously, you probably burn 5w each time you open the fridge door!

So sapnho should leave the SBR on and turn the fridge off?

This whole energy consumption thing is getting so ridiculous! The press runs stories that make you feel guilty about your 5W energy consumption while the guy who runs the media empire is flying off to dinner in Paris on his private jet.

Try to acquire some sense of proportion. In the overall scheme of things 5W is nothing. It is so small it is even undetectable on your own electric bill.

If you want to save the world, focus your personal energy where it will do some good. When tackling any large problem you have to analyze it and figure out an approach that gets the biggest impact with the least cost/effort. Why devote energy to saving 5W when a similar expenditure of personal effort may save 5 Megawatts? Think BIG, not small.

For example, instead of posting messages on audio forums about saving 5W, post messages to your congressmen and senators about the big problems in the world. Organize groups of people to do the same. The effort is the same but the effect is potentially much larger.

There is an interesting article in the Los Angeles Times today that says an alternate view by an increasing number of scientists is just to accept the fate of a changing world and don't try to stop it. They argue it is cheaper to adapt than to try to hopelessly change the dim future.

Hey guys, I don't know about energy prices in the US, but in Europe it is damn expensive. So whilst saving the world maybe nice, this is about my personal energy costs and I like to know how much something costs so that I can make a conscious decision how to deal with it.

BTW: A gallon of gas here costs $8.82. Drive safely! :-))

And I agree, 5W is nothing. Thanks for the info.

Still, installing the power saver plugin is very little trouble.
I find that turning my SB3's off with the SBC is quite a hassle, the
powersave pluging fixed that nicely.

It's nice, but do you know if it is actually saving any power? The on/off function in the SB is a software function that does not disconnect it from the power supply. It has to remain powered up so you can turn it on again. If you're really serious about saving power you should unplug the SB power supply when you're not listening to music.

In my case it does save power, because PowerSwitch (another plugin)
switches off my powered speakers.

Probably not, but it is protecting the screens of my SBs (at least the way I have it set up). My SB2 is suffering a little bit of screen burn (where the ":" between the hour:minute is on the time). Only really noticable when brightness is on high, but I'm hoping that installing the Powersave plugin will stop it from getting any worse and/or occuring on my SB3s (although I think they have a different screen type from the SB2s anyway).

Same screen, different colour filter.

That's the first time I've ever heard anyone report screen burn on a squeezebox.

You could just set the off screen saver to a blank screen, of course.

Screen burn may not be the correct technical term - is very much what is described here:

http://forums.slimdevices.com/showthread.php?t=36636#6

When on full brightness, the ":" is between the hours/minutes is not as bright as the surrounding pixels to the point where you can identify the shape of the ":". As I said, it's barely noticeable - and isn't intended as a complaint - my SB2 has seen pretty heavy use over the years. I now use the Powersave plugin to automatically switch off the SB and ensure a blank screen, which I haven't done before.

I have it too, it's particularly noticeable with scrolling text.

I'm seeing it here as well on an SB2 that always runs the date/time "screensaver". As Siduhe says, it isn't comparable to burn-in as seen with CRT monitors. More like "burn-out" - the pixels at the center of the screen are no longer as bright as the rest.

... but not with the controller AFAICT. There seems to be no screensaver setting to turn off the screen altogether when idling in the cradle. If you leave it out of the cradle then the screen does indeed turn off.

To be fair, you can certainly set the screen to switch off when in the cradle (mine is now). The enh req you link to is about having it do that when the player is stopped but stay on when it's playing, a slightly different requirement.

How do you do that? I've tried all the settings but cannot get my screen to
shut off in the cradle.

The screen on the controller is an LCD with an LED backlight. There is no danger of burn-in.

The option is something like "dim screen while charging" - once docked the backlight will go off after the appropriate timeout.

Ahh, yes. I saw that dozens of times and never considered it would do that,
because it doesn't actually *say* that. :-)

Mine goes blank even when lying on the table. What I really like is that as soon as you pick it up it comes on - some sort of motion sensor I guess.

OK, that doesn't seem to work for me. I have a fully-charged SBC and put it
in the cradle with this flag set and it may be a bit dimmer but the screen
is definitely on and I can see the clock. Here's what I want:

If the SBC is in the cradle and there is music playing, I want the screen
on. Otherwise I want it off/black. I don't care if the player itself is on
or off -- the distinction is almost meaningless for an SBR anyway.

Mine goes blank on the table, which is great I agree. I want it to go blank
in the cradle too and I can't get that to happen ever with any combination
of options that I've tried.

And this is what I am after. When the controller is in the cradle, I want the screen off when the player is stopped and when playing I want the screen on so I can see what is playing.
