Here's the quote from the LLP
"Little Lab Power Dimunitive Audio Reference.pdf"

Quote:
Inside the LLP is a plug in jumper block for any voltage from 100-260 VAC@ ether 50 or 60 Hz.
I wasn't sure how to read it except that it had to be reconfigured with a jumper.

My understanding of "universal" voltage means plug and play (no jumper, no switches)

FWIW, I'd love to be proven wrong...

its a regulated PSU I dont see how you could design a plug and play regulated PSU that was auto sensing. although I didn't have to do anything with any jumpers at all. I would think they would set it for you country before shipping. if it were a switching PSU it would be different, but if it were a switching PSU... it would be crap. My understanding of what anything 'universal' is; is something that can be used universally

I gave up on electrical power engineering after a semester of it :P

But google seems to suggest there may be options...

"Regulated power supply" 100-230 - Google Search

maybe i need to rummage through my company catalog. According to the google search, some of my company's devices are powered with universal voltage PSUs which are also regulated. Hmmmm...

I actually was under the impression that it was a universal voltage PSU, and my friend travelled with his recently without whining about having to reset any jumpers. i'm no EE either and dont know the ins and outs of that side of electronics much really. only the audio side and cables and whatnot. Sure there are other options out there, but there wont be too many that are designed with uber high quality audio in mind other than similar devices for other amps. but I do know that switching PSU's are inferior to regulated PSU's when it comes to audio. and a switching PSU could actually cause damage to lisa and possibly make it explode

I cant get enoughhhhh of it.. and to those thats thinking of skimping on the LLP.. DONT.. the thing is worth the money. it is as qusp mentioned, useful!
What SVS do you have? And lol at "portable" solutions three or four boxes 1' tall.

the bottom box is the power supply, and LOL at your inferior sound hehe. just kidding; but seriously if I could get anywhere near the same quality but with only 1 or 2 boxes I would, but sorry that just aint happening

qusp,

how long does it take for the LLP to fully charge the XP?
post #53 of 229
The LLP charges on a one to one ratio. If the battery runs down in 10 hours the LLP will take 10 hours to recharge it.
post #54 of 229
So 80 hours for the XP!???

That's the longest I ever encountered to charge a battery! :P

maybe so; but the battery will have a very long lifetime as the charge isnt so rapid that it stresses the cells. plus you will find that you just come home and plug it in because the lisa gives better sound when connected top the LLP. besides how often to you need to have 80 hours of continuous use out of the lisa?? so if you leave it on overnight you will always have enough juice for the next day. I also have never come across another amp that has even close to that much battery life either, so its fine by me

I guess my experiences with batteries on my notebooks is that it is bad to keep charging batteries since there's a limit to the number of charge cycles you can supply.

So I try not to charge the batteries until it is close to being depleted.

thats a different thing though; the lisa and LLP are designed for the amp to be put on there when you get home and use it like that. there are no ill effects from this at all.

The XP is just powered by a very large pack of NiMH batteries (12 if I remember correctly), right?

Same basic rechargeable principles apply..

That's the routine you use with NICAD's- you discharge to 1.2 v prior to charging. For lead acid & Lithium batteries you're not supposed to run them until near flat. For NIMH you can just top up anytime.

like I said; no ill effects at all; thats the whole point of the LLP, its not a glorified $300 charger; its a PSU you are supposed to power it with that while you are at home.
