I'm considering building a outboard battery power supply for my mv100. From posts I've read both here and from elec. engineers on rec.pro-adio the the unit it VERY similar to the Sonosax.
According to folks I've talked to and conversed with it uses the same ssm2017 chip. People have said it's the same circuit essentially. with the "sax" having balanced outs and continuous gain.
I've tried getting beyerdynamic to fax me a copy of the manual, but they can't find it. Anyone got one? How about a schematic?
Anyway, why does the Sonosax allow 12-24 volts for external powering and the mv100 say only 24v. Is this just a misprint on beyer's part? Has someone tried powering it with 12v?
Along those same lines, why would it work fine with 18v (2x9v batteries) but require 24v for external power?
I don't need the full 48v of phantom power....I'd only ever use it for my AKG 391's...which work with 18v of phantom power.
I would love to hear what people think.....
Peace,
Zach
