this is a head scratcher
« on: October 05, 2019, 07:46:26 PM »
looks to be nothing more then a transformer to go between your microphone and your mic pre... of course I could be way off there as they claim a 26dB boost in signal and it draws 5mA of 4pohantom to run it.  any  ideas on this other then a fet booster?

I agree, it sounds like a transformer plus simple FET booster.

Naaah... They say it's magic. There's even a video that proves it.  8)

I would not think it is a  fet
Read the write-up it is designed for dynamics and has a higher than single  fet mA draw.

You can find an inside picture on the web it does not show the circuit but it gives a clue to the size of the circuit

I would guess it is based on a circuit(s) from books etc.  from the 50's or 60's

I would GUESS something like figure 4 with a EF driving a transformer.
If you search for preamps you will find schematics something like this. It could be adjusted for the mA draw and powered from phantom

Look at the PDF page 60 for some ideas

I've seen dsp powered from phantom power.

Who wants a fuzz box for mics?

It's completely open to conjecture; could be anything, BJT, FET, opamp, even subminiature vacuum tube. I just don't want to guess, I don't want to break the magic spell.  ;)

Since they mention a magic transformer, I would think there is some iron and copper.

Unfortunately, listening to a number of records and seeing the ads for dirtifyer plug-ins, I would think there is a market for that.

"Size: 44 x 21 x 19 in (111 x 53 x 48 mm)" - So is that rackmount or is someone bad at math?

Fuzz Box for mics? Why not, it seems a good idea.

In the case of this "Launcher" I'm just really confused by the marketing
