I will ask Tritonaudio about this, also the Outputimpedance and the current used, think read 3 mA Gentlemen here the answer:
Your questions about the FetHead Phantom, would you like to know more, feel free to ask:)
Output impedance : 600 Ohm
Powerconsum: 1.5 mA (it is on a diet compared to a normal FetHead)
HF sensivity, some peple can here Radiostations with this item:
All types of FetHead are NOT sensitive to RF and very well shielded. What
could happen is the following: If the microphone attached to the FetHead
is not properly grounded it could become sensitive to RF. In most cases
this is fixed by restoring the grounding of the microphone body. The
microphone body is usually grounded by a screw which secures the xlr
connector and which also electrically connects the microphone body to pin
1 of the xlr connector. Repeatedly sticking and pulling out the
microphone cable from the microphone can loosen the screw which makes the
microphone less shielded. Bad microphone cables and worn out xlr
connectors can also have influence.
Hope this helps
best regards,
