Usb mic in MPC One.

Hello. Excuse my English, this is a Google translation. I recently bought a usb microphone, a superlux E205U to use with my MPC One with the latest firmware. It works very well and the sound is very clear, but I don't know how to regulate the recording level. With the regular input of the MPC it is obvious, but with the usb mic I do not know how to do it, since it does not have any potentiometer. Regards.

I think you can only control the level in software.
You are correct that there is no potentiometer.
The condenser capsule probably connects directly to the internal A/D, with no amplification.
