Smallest Pre-amp with 48v Phantom Power

[page]

Even with stealthing I would go for front and rear panels.

Soldering a six-pin cable may be a bitch and not very durable.

Ah, I just have someone else I trust do that. 

The bummer in my experience on that is the mini-xlrs don't work well as either stubbies or right angles, otherwise I'd be more open to the idea of stuff on both panels.

...the size of the 9100 preamp with FULL 48 volts and operate on 2 AA batteries or 9V we have yet to determine this.

Chris, Jon, I'm thrilled to hear about both projects.
What kind of runtime are you aiming at? Chris, if you're toying with the idea of 2 x AA, this would have to be primary Lithiums in order to crank up the voltage to P48??? Or is it really feasible to do this with 2 x 1,5V NiMH?

Awesome - C.A. and Naiant

sounds like great news all around!!!

Need a vote on feature set though, here are two options:

- All front panel controls:  6-pin mini-XLR, three-position gain switch, high-current minijack out, on/off switch, dual green/red LED for on/peak/low battery.  Basically the same as tinybox but with P48.

- Rear panel input:  2x 3-pin mini-XLRs on rear; front panel:  minijack PIP input, three-position gain switch, high-current minijack out, low/off/high power switch, dual green/red LED for on/peak/low battery.  This is a littlebox in an extended tinybox case.r

As a Tinybox owner, I definitely like having all the inputs on the front panel.  More convenient for running stealth of course, but I prefer that for running out of a bag also. 

Sound great though, kudos to both Church and Naiant -- what would we do without these great entrepreneurs?

Sound Devices MP-2 can do it, so it's doable.

AA NiMH are only 1.2v

AA Alkaline or Lithium are 1.5v

Maybe expensive, but is a beauty

how does the stereo xlr work?
split into a dual

[Roger Gustavsson]

Ground/screen is common for left and right channels, as it use to be. The other 4 pins gives you two differential/balanced channels. It can be split in two 3 pin XLRs.

Are You talking about the uPRE? the uPRE has unbalanced out in one 3 pin mini xlr (groud, left and right).

Sorry, did not see that it has unbalanced outputs! The outputs can be impedance balanced. You will need to know (or measure) the impedance of the outputs. It is not a must or necessary to use a balanced interconnect. What do you want to connect it to?

i don't want it, i was just wondering
i see it has dual 3pin xlr in and 1 3pin stereo xlr out
