Technology integrated cms (406X type) circuit. Were between XLR microphone, you leave online (close to 0dB) XLR. We have a green LED light (LED) to indicate the presence of voltage.
Then we find a mini switch to toggle phantom power mic +12 V or +48 V (no off position)
Power is supplied via a 230 V / 12 V external adapter. Should even have the right to be wrong direction on the +12 V, it does break anything.
This is a preamplifier for microphones (rather static) with phantom power, without any settings, or gain any more bass-treble, just a preamp.
Dimensions: 58x32x103mm, weight: 360 grams Power consumption: 2W.

OVERALL OPINION

To deceive in connection here should really do it on purpose, it is even almost impossible.
I can not find the little manual, but it is very simple, see above in "features".
