Topic: JB3 external power

[sickrick43]

Use the CAR ADAPTER and hack it...

But DO use modular connectors, so you can use the cig-lighter part too. (to run JB3/charge internals in the car)

I use crimps and shrink 'cause I HATE SOLDERING.  Burn my damn fingers EVERY TIME (and this from someone who's been a field tech since '79).

so, whatcha got going on there rick, let me in on the external power secrets;-)

so, whatcha got going on there rick, let me in on the external power secrets;-)

I had bought 2 EC-90 6V/12V systems, figuring on powering my V3 & D-10 Pro.  The JB3 is just so much more cost effective.

So, the EC-90 has 2 four pin XLR out's, 6V and 12V.  The 6V end runs the V3 & the 12V end has the (-)tip connector for the DC adapter in the D-10, and a second wire with a Radio Shack female DC power cord, so that you can used whatever tip you want, to run a 12V device.  The Creative Car Adapter has a RadioShack Male DC Power Cord plug on it, and the snipped off car-lighter-thingie has a female plug - so it can be plugged into the eco-charge cable or car lighter cable.

As commented somewhere else, I ran the V3 for Cracker, STS9 & moe (over 4 hours total) and still had 2 lights left of meter (60-20% charge), so I doubt the creative adapter was even drawing the 2.5a listed on the label.

No secrets here, I always share wit my friendz...

see, rick, i dunno if its worth all that when i can get 6.5 hrs out of the 2 batt bays

[sickrick43]

I've gotten down to 1 bar on the internal meter (with 2 fully charged batteries) at about the 4.5/5 hour point (dead new years).

It may not pay to bother with the extra cost/weight, but in festival mode.  Since I've gotta haul the battery anyway for the V3, might as well run the JB3 too.  If the SLA looks like it might not go the rest of the night, I can pull it OFF the JB3, and there's still 5-6 hours left on the internal batteries.

For a night out at the local club-gig, it doesn't really pay.

i see, so you have 2 FULLY charged jb3 batts, PLUS a fully charged rc batt, you plug the external power in WITH the 2 jb3 batts in, when the rc batt is getting near dead, pull the external batt and it will go into internal mode, but doesnt the jb3 freeze up or something??? i thought i read that somewher on here

either way, it is great for festie mode, and i might have to start toying around w/ that idea, if i had 2 rc batts high in mah's, and a set of jb3 batts that i have, i could use the 2 rc batts first and then when those were running low, id just toss the 2 internals in in case of a freezeup, sound about right, im curious to hear all of your jb3 experiences rick

thanks bro

Not 2 fully charged RC's.  The RC battery is for the C02/Hosa optical.  The "big" rig batteries are Echo-Charge EC-90 SLA's, and were bought to run the V3 and the D-10 Pro.  I used to run the JB3 off its internals.  Since I'm confident enough in the JB3 to not run the D-10 (or have to carry it - I still bring it to club gigs and run the board DAT and the mic's JB3) I run the JB3 off the EC-90 12V out, along WITH the V3 off the 6V.  If I'm in festi mode, and want to conserve juice on the SLA for the V3, I can always switch to running the JB3 off the internals (though obviously not in the middle of a recording), and they will still have a full charge, having not been used up until that point.

Sorry to be confusing...

Eco-Charge EC-90 http://www.ecocharge.com/batteries_ec90.html

They ain't CHEEP either.  I bought 2 X-Mas thinking D-10 & festivals, not even thinking about running the JB3 off them.  They sure feel HEAVIER than 5.5 lbs. apiece when yer hauling out of a show after a long nite.

ahhh, i see all clear now!!!

damn 12v's, i know theyre heavy as all hell, but if ya wanna tape alot, ya gotta sacrifice an achey back the next day, something that im willing to suffer thru

so how long does the jb3 last off of a 12v 7.2a batt, i wish we could rig that up w/ a 6v tho, i really dont wanna go into the 12v realm just yet, not till i get a 722 at least

[F.O.Bean]

oh and thanbks for the jb3 help/chatting, i wanna know everything there is to know about it ala my d-8

Unfortunately, the JB3 won't run off straight 6V, and DIY'ing a voltage regulator won't work, because you need just over a volt to drop on the regulator - leaving you not enough voltage to run the JB3.  You could "probably" make a 9V RC work, with a DIY regulator, but the discharge curves are such on metal rechargables, that you don't get much warning before they're below the threshold required to run the device (found this out with my C02 & RS Rechargable 9V "square" batteries.  One second the light is nice and bright, the next second the decks go into pause.

I tend towards OVERKILL myself anyway.  I'd rather bring too much gear, than not enough.  Too much won't keep you from coming away with a recording, not enough can kill your whole outing.

hmm, would a boat battery work?

If you got something to haul it with.  I had a buddy that hauled a 22Ah Diehard car battery into shows (front of board no less) to run his Nak PCM & Sony Beta deck.  Sometime tapers will do strange and outrageous things to get what they think is the best rig to record with.

ha, thats awesome.

i wasn't really serious, but it'd be funny to see someone in the section with a huge car/marine battery.

[F.O.Bean]

i was tossing around the idea of getting a small 12v system JUST for the jb3 in long hauls

so all id need to do is crimp that cable and BAM, no voltage regulators or anything, just splice car cable and crimp???

thanks
