Preamp for condenser microphones

FetHead Phantom is a low-noise, high quality, in-line microphone preamplifier. It provides improved sound for condenser microphones. The electronics are housed in a robust metal chassis with a balanced 3-pole female XLR input and a balanced 3-pole male XLR output, rugged enough for use at home, in the studio or on tour.


Which microphones benefit

FetHead Phantom is a FetHead version specially designed for condenser microphones. It works very well with all condenser microphones. FetHead Phantom is also an indispensable tool for mobile recording and a real upgrade for camera microphone preamps, because it lowers the noise floor.


Phantom power distribution

FetHead's Phantom circuit uses 48v phantom power but also passes it on from its input to the microphone, so the condenser mic is powered with the same phantom power.

User product reviews


"How long may the XLR cable be to power the FetHead?"

About 125 - 150M, dependant on cable capacity

"Can I use the FetHead on the preamp side of the signal chain?"

Yes, it is perfectly possible to use a FetHead on the preamp side of the signal chain

"I would like to boost my Røde NT1a. I see you sell the regular Fethead, the Fethead Phantom and Fethead Filter. The Røde NT1a is a condenser microphone, so I think the Fethead Phantom is best. Which Fethead would you recommend?"

The rode NT1 needs phantom power to operate and don't have the battery option, so we advise to use the FetHead Phantom.
