TritonAudio FetHead

Philosophy

Inspired by the positive results of the BigAmp we wondered if a phantom powered, high quality preamp preceding the microphone cable could improve the sound quality of a ribbon or dynamic microphone. the results were more then convincing. Enter FetHead, our newest innovation in phantom powered preamp design. While testing FetHead we noticed an overall increase of sound quality and a change of tonal character of the attached dynamic microphone towards a more open, controlled sound.

Which microphones benefit

In short, we noticed an improvement on all tested dynamic microphones. A Shure sm58 for instance, sounded more responsive over a broader frequency range. When mated with a high-end dynamic microphone like a Sennheiser MD441, FetHead really shines. Ribbon microphones benefit greatly too because of a much better impedance match, which lessens the load on the microphone, thus giving it better transient response characteristics. FetHeads high quality, low noise signal amplification also extends the usable range of a ribbon microphone, by making it more suitable for recording softer passages without introducing noise. Some ribbon microphones do not tolerate phantom power, FetHead's circuit uses Phantom power but shields it from its input (and the microphone's output), as a result it offers effective protection to the microphone.

Low noise

Fethead uses low noise jfets configured as a double class a amplifier. Jfet's are among the most quiet amplifying elements available today. The calculated noise figure of the FetHead based on the jfet's datasheet is lower than we are able to measure. In the real world the noise injected by a FetHead depends on the noise generated by the pantom power supply, if the power supply is quiet, FetHead is quiet.

How it works

Attach FetHead on to a balanced microphone cable and plug it in a dynamic microphone, switch on phantom power and enjoy FetHeads Natural open sound!

We recieved some really nice product feedback from KRAMER:
I COULD NOT DO MY JOB AS A RECORD PRODUCER WITHOUT THE HELP OF PRODUCTS MADE BY TRITONAUDIO. THAT'S A SIMPLE FACT. NONE OF MY VINTAGE RIBBON MICS WOULD SOUND THE WAY THEY DO ON MY RECORDS IF I DID NOT HAVE MY FETHEAD PLUGS. I OWE A HUGE DEBT TO TRITONAUDIO. THANKS FOR DOING WHAT YOU DO, AND DOING IT SO WELL!
