I've heard anecdotal reports of JB3s overheating and shutting down. Not usually from a reliably competent source. Since tech wise we here seem to have a better understanding of our gear, I figured I'd ask you guys if this has ever been an issue at outdoor fests.

I had it happen to me once. I was on a road trip and the jb3 was on the seat next to me in the sun. It all of a sudden shut down. I was able to turn it back on, then I just covered it up and all was fine.
-
I'm kinda having the same concerns, Chris. I always carry two small portable umbrellas with me for festivals and outdoor taping. One to clamp to the stand, obviously. The other I open up and place above my gear to put it in the shade and protect it from the direct sunlight. I'm guessing this'll be enough to keep the NJB3 and the rest of my gear from getting too piping hot. We'll see...

good call....I've got one stand umbrella, getting a second to cover the gear sounds like a plan.

Mine overheated and shut down when stealthing inside a packed and hot bar. Missed the last 2 minutes of the show due to that. The recorder was inside my bag when recording. Nowadays I keep it open. Haven't happened since.
-
take the battery cover off the JB3 so there is a little more airflow, bring a thick white towel to cover it if you have no shade. As long as it can breathe a little and is not in direct sunlight you should be OK.
-
I am buying a second JB3 for festivals where it is hot and I want to tape almost every act...this way I can alternate JB3 and allow one to cool while using the other one.
-
Why not just make a little fan for it or something? Like computers have to cool them off, same sorta thing.
-
or go to wal-mart or something similar, and just get a small portable fan, inbetween sets or something, let it run on the jb3 ;)
-
i had my jb3 shut down on my once so far. left it in my car while i was at work and on my ride home it died on me. let it cool down a bit and it worked fine after that. id be a little nervous running it at a festival, but if u keep it covered by a white towel so it stays out of the sunlight i'd think you'd be okay.
-
and such a simple way to take care of it justin, just get a hand drying towel, that would be perfect!!
-
Mine shut down just last Sunday. I had it covered up, in the shade, but it was under a rather thick moving blanket. Around an hour and ten minutes into the the set, I checked the JB3 and it was dead. >:(. I immediately pulled it out and set it in the open, and it ran fine for the remainder of the day. I have since tested it in the open and tucked into a padded camera bag....I'd recommend keeping it in the open (and shaded) as much as you can. I'm not surprised this is happening. Looks like a guy should run DAT as a back up to the JB3.... :)
-
seems they can only take about 1 hr or so of heat and they shut down!
-
Yep. The moral of this story is "Keep your JB3 where it can breathe free"
See...there's a reason why I TAPE music instead of MAKE music. I suck at the Internet and at poems.

sounds like a floyd song!

Recorded for about 10 hours at the roo. 3.5 solid outside in direct sunlight(while running about 7 hours overall). JB3 was in targus bag covered with a bandana. Never had a single problem with the recorder. Only problem I had was with the optical cable coming from the UA5.

Hm. Well, I don't have a problem with my optical connection...yet...(finds some wood to knock on)...
guess each unit might have its own little quirks (?)
Overall, I'm really happy with the ease of use and the lack of media required to tape using the JB3. I'm gonna stick with it (and might just get a second unit someday and ditch the DA P1) :)

Off the wall thought............what about making a tent out of aluminum foil and
chopsticks to cover the jb3 ?
Yeah, chopsticks............... :D

At the very least, this will block all the mind control beams sent by all those government-sponsored satellites......

when you're done with it you could sell it to some spun w00k as the ultimate clothing accessory.

Mine overheated during Los Lonely boys (30 mins in). It was sitting in the pouch all zipped up in my backpack. It was hot as hell in there and i should have known better. I fired it back up after i realized it was off and a few minutes later it over heated again. I lowered my stand and wrapped it up and put it in my roomates camelback to cool down for yonder. during yonder i took a beach towell and clamped onto my stand and the guy next to me to make a shade cover. Didn't have any problems after that.

mine bailed twice at telluride :-\

Mine seems INCREDIBLY heat sensitive...I put mine (in its flight case) in my car...the car was hot from sitting in the sun...and I did run back in the house once...so it couldn't have been in the car more than 10 minutes before I left for a 1 hour air-conditioned ride to a friends house...when I arrive...take the case in...the JB3 wont start...wont get past the boot screen...let it sit for 30-40 minutes in his air conditioned basement...finally it works.
I dont think this unit would have even started at B'Roo...
The unit never feels warm...I havent even used the batteries yet...I figure they must generate some heat...
I've seen at STAPLES some "Laptop Cooling Mats" that might be handy for JB3 users...they look like a thick slice of swiss cheese...and would likely run off DC...I'll check them out when I go to town next. I would even consider drilling some holes in my unit if it would bring it up to DAT-like reliability...
-
hmmm, ive held mine when its been pretty darn hot but *knock on wood* it hasnt shut off on me at all yet!!!
but i always run it in a bag w/ the top open and ive had zero problems :/
johnr- what happened at telluride??? werent you always in the shade ???
-
I take a small chair, fan, margarita and self-massager to keep my JB3 "cool" :P. JK. I havn't had any problems with mine at all, I keep it out of direct sunlight though so IDK.

mine shut down once, it was zipped up in a bag w/ ps2 and ad20. I left it open after that and no problems. The key is breathing room, I keep it in a jean jacket pocket most stealth jobs (try to swing it back and forth slightly for air)and never had a problem yet.

Had mine shut down last night at an outdoor show after the sun went down. Had my bag open but the JBS was vertical with the back resting against the seperater between the it and the UA-5 which was also getting pretty warm. Shut off 12 minutes into the second set.

could we perhaps hack the firmware such that the device ignores the heat threshhold? or that such a thresshold can be defined on the fly?
that would suck for the one time the jb3 is about to actually melt, but ... in all other cases it would make for happier customers.
creative, hear our plea! user-definable heat threshholds are a must!

Let's make an option for some better meters as well while we are at it ;p

hehe, that would be the v3 ;)
ive ran a dmic for years before the v3, and the 4 lights like the mme just dont cut it for me, im also color blind as a bat, and i dont think i could run anything but the v3 at this point, for my color-blind ass, i couldnt ask for more :)
levels can be a PITA, if you dont have a dat, it can be ROUGH :P
i like the way ppl are adjusting for running jb3's w/ the svu stuff tho ;)very creative ;)
my point is, im a lazy taper at times, and the more lights on my pre/ad means less messing w/ my recorder :)
