1:30 transformer ratio

[Kamel]

i have some beyer 1:30 transformer, so i would like to use it reversed (30:1) to do a passive DI, loaded with a 200 R and maybe a zobel network.

is it a stupid idea or maybe do you have some idea to use them?

cheers

The 30:1 transformer could be excellent as a DI.  Why terminate the secondary?  Have you measured the frequency response feeding your favorite preamp?

the beyer tranny is a 200:180k transformer and to show to the next stage (mic preamp) an optimum impedance (mic impedance)

Wow, this is one of a kind. Do you have more of these? i would love to put it in a tube micpre...

sorry, i have only 4, 2 for a NYDAVE one bottle, 2 as passive DI, it was from the kubi beyer group buy

If that is truly the impedance ratio, I would expect to see limited bandwidth as a result.  You tend to lose a lot of response, for a limited increase in gain.  Check them out first.
