shipping tomorrow or thursday (if i'm snowed in, as forcasted) bro.
sorry for the delay, i've been unable to get to the bench much in the last week.

thanks nick. not busting your balls nor do i have anythng coming up too soon.


for those of you who power the 671 externally: is the polarity reversed, like on the UA-5? i know i saw it posted in one of these 671 threads but couldn't find it.


polarity IS NOT reversed on the 671 ala ua5.

okay, so just to verify: radio shack adaptaplug, connector M & B to use a lithium ion 9v w/ the 671. i should line up + and TIP on both the M & B side, right?

the 671 will shut down after the 9v starts to lose juice. faster if you run phantom.

that's what i figured. however, if you have internals and an external power source, will the 671 switch over when the externals die without any problems?

Well I finally had time to do a little testing on the WalMart battery.

AKG 483 > Oade ACM Marantz PMD-671 (24/48), phantom on, display light on.

I filled up 2 4GB CF cards + 12 minutes into the third before the last green light went out.  So roughly 8 hours of run time.

It finally died 18 minutes later, saving the recording.  All of this with a two year old battery, one that's been used a LOT!

I know.
I couldn't get my dam'n'd grommet in the whole to tighten that up. 
Its secured underneath, just so you know.

I've got a few more of these, for anyone wanting a system.

Nick,

Does your price include the cable w/ DC plug?
Is it possible to get a cord with a right angle DC plug on it? (to minimize the deck's width as much as possible?)
How does it connect to a charger?
How long on a charger does it take to reach a full, reliable charge after use?

Thanks for any info....

 :)

it comes w/ a charger that is kinda quirky, but its not that difficult to deal with. it claims to charge in 2hrs. i havent tested how long it takes, but i will tell you this: i recorded last nite for 2+ hrs, then formatted the card, and let it run til it filled the 4gb card up again. so far, its still on 12+ hrs later. this battery is the shit.

I can put on an adaptaplug end so that the RA barrel can be used (for anything).
but honestly, the little barrels I use fit better and are much smaller than the radioshack cable w/the modular tip.

12 hours strong.
thats pretty sweet.

So, the 671 manual says that the power consumption is about 6w on average. So, does that mean it pulls .5a? (6 w/12 v = .5a)? Is this correct? Does that mean a 7 mah battery should run the thing about 14 hours via the external power input (but using DC)? Any insight most appreciated!

Lastly, if Neumann KM1xx draw about 200 milliamps (is that spec correct?), that means these plugged into the thing should draw about 700 mah total (with light and phantom powering on)?

So.... a 7000 mah battery should run the above setup for about 10 hours?

Thanks for any input!

 :)
