Nice looking bag Marc, I posted photos of my rig combo which uses Portabrace and Marantz cases strapped together in another tread.

I use one battery to power both devices Tekkeon MP3450 it's got a dedicated 5V output to power the PMD661 and I set the adjustable output to 12V to power the MixPre-D via the Hirose connector.  This battery will power both devices for several shows before needing a re-charge and should fit in your gear bag.  Here's a photo showing the battery as mounted in the Portabrace bag and another showing the bags strapped together, provides gear protection, allows full access and viewing in a nice compact setup for the combo rig.

Yes, I see your bag.
Nice so and probably more usefull to have a look on time-code for example.

For Tekkeon MP3450, it's a good idea.
I understand there is a fix output to 5V and another one variable (12V possible).

Is it easy to wire a Hirose connector on the box side?
For 5V , is the same connector for Marantz as for desktop ?

You'll need to make or buy a Tekkeon cable to Hirose 4-pin power cable for the MixPre-D.  You'll also need to make or buy a USB-A to 1.7mm I.D. x 4.0 O.D. power plug for the PMD661, best to use a beefy USB cable for this.

I wouldn't necessarily recommend that a beginner attempt to make their own Hirose cable but go ahead if you have proficient soldering skills.  Good dexterity, eyes and/or magnifier are certainly useful with Hirose 4 pin connectors.  I made my own but if you're not up to it yourself get in touch with Ted/GAKables for these power cables.

No, no, I don't want solder an Hirose socket, my dexterity has some limits ...
XLR-3 / RCA: OK but more tiny, I don't try.
It's the reason why  I bought the DV SQN-R , all is included.
Thank for the link Ted/Gakables  ;)
For 5V, I think it's possible to find an USB-A to 1.7mm I.D. x 4.0
For 12V, I don't found a Tekkeon Hirose cable.
Is there a specific socket on  Tekkeon side (12v) ?
If yes , is it easy to  solder ?

About Vu meters on PMD661  - signal from Mix-Pre-D (thru AES/sp-dif link):
- 1Khz 0 dbu on Mix-Pre-D = -20dbFS on bargraph PMD661 (I think it's normal)
- 1Khz 0 dbu on Mix-Pre-D = -40dbFS on LED scale PMD661
Why such a difference ?
