The hirose connectors are available for about =A37 on ebay. There are 2 way=
s to 'wire' it for power. One pin powers it only ( and charges the battery =
only when the unit is switched on ). The other pin does all that as well as=
charge the battery any time it's connected to power even when the unit is =
switched off. ( a diagram is available in the manual or on the SD website )
I know you are really only interested in getting a ready made lead for it, =
but that information is worth you knowing, anyway.
The DC supply to the hirose connector can be anything from 7.2v to 18 v. I'=
ve actually run the machine for 6 weeks continuous with the input at 21v wi=
thout any problem at all. Actually, mine is a 722, but I assume the power h=
andling is the same.

Hi
I recently purchased a Sound Device 702. I would like to record at times up=
to 18 hour running 2 mics using phantom. I understand the 702 can be power=
ed by an external battery using the Hirose connection.
I=92m sure it=92s possible to make a cable =A0but is there a commercial cab=
le available to connect to a suitable battery?
What size battery is needed? Does the battery need to power the recorder at=
7.2v (as the power pack) or 12v ( as alternate power supply at home- 240v)=
.. My understanding is the Hirose connector has 4 pins. 2 powers the unit, =
the other 2 supply power to power pack. Having all 4 pins wired would power=
both recorder and power pack, requiring 12v. Wiring to correct 2 pins just=
to run the recorder requires 7.2v. =A0
Any advise would much be appreciated.
Cheers
David
