Preamp for live and broadcast application

FetHead Broadcast was developed in conjunction with Dutch Broadcasting and facility service company United4all. It is based on technology used in our product FetHead. General layout consists of a high quality jfet gain stage, followed by a low impedance output buffer to enable output drive to long cables (up to 3000 meters).

FetHead Broadcast offers 25dB's of low noise, high quality amplification which can be applied to either dynamic or condenser microphones as phantom power is transferred to the microphone.

During live performances microphone signals often travel through long cables. If they travel adjacent to power lines or dimmed light cables, audible signal interference into the microphone cable often occurs usually resulting in a polluted signal. The FetHead Broadcast prevents this from happening by amplifying the signal before the cable. It improves the signal to noise ratio and offers a high quality signal to the mixer. Another advantage is that the FetHead Broadcast does not need main supplies or batteries.

User product reviews


"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

"What is the difference between the regular FetHead and the FetHead Phantom?"

A regular FetHead is designed for dynamic microphones and ribbon microphones, it has a relatively high impedance of 22k which allows the microphone the microphone to operate at "no-load" condition. A FetHead Phantom is designed for for Condenser microphones or other Phantom powered devices, it passes Phantom Power to the microphone.
