Passive DI + Phantom Power?

[jussi]

Hey friends,

I have a question... I own a passive DI-box that I use with my electric guitar and acoustic bass (it has a pre-amp).

The thing is that yesterday I thought about pressing the phantom power button on my mixer and I was thinking that it would do nothing like it happens when you are using a dynamic mic...but, the sound changed a lot!

Is this a common thing to do or my DI transformer is going to blow in a few days?


Thanks

I have never seen a passive DI that was affected by phantom power. Which DI was it?

Behringer Ultra DI 400 P

The funny thing is that it sounds good both ways and with the guitar too.. voodoo?
