Looking for the internal schematic for this mic, it provides balanced output and requires phantom power. I'd just like to
understand the internal circuitry.

3382 Schematics
Hello PB2
While looking for infos on 3382's best Voltage for phantom power I remarked your post from 2007!
I do have the schematic and parts placement of 3382 on a pdf.
Still looking for it?

I'd appreciate it if it' still available.
The microphone is apparently spec'd for a phantom power range of 10-30V which seems odd since phantom power is typically 48V.

There is also P24 and P12.
Lots of newer mikes take very wide range of voltage without complaint or configuration. AKG414 will eat 55V down to nearly 9V, all the same, because it runs 9V internally and is is a current limiter plus a voltage regulator. Other mikes run a fixed current like 2mA with 60V rated transistors, the actual operating voltage not very important.
Some of the oldest mikes used 45V-from-48V as capsule polarization, but electrets and modern switcher supplies have eased most of those off the market.
