TRITON AUDIO FetHead Overview

The FetHead from TritonAudio is a low-noise, in-line microphone preamplifier that provides improved sound for ribbon and dynamic microphones. The electronics are housed in a metal chassis with a balanced 3-pin female XLR input and a balanced 3-pin male XLR output. It is suitable for use at home, in the studio, on tour, and more.

FetHead's circuit uses phantom power but shields it from the input and the microphone's output, providing protection to the microphone. Attach FetHead to a balanced microphone cable and plug it straight into the microphone. Switch on phantom power and enjoy clean gain. This works with any microphone.

Using this preamp for my Rode NTG-2 and Zoom 5. Made a noticeable difference, would purchase again if I had to do it over. Thanks!

Pretty good with PodMic

Used to increase gain on RE50 in location work. Nice bump in gain, solved my problem.

Simply the best

I own both Cloudlifter and multiple Fetheads. Both are clean and natural. Cloudlifter sounds a little louder with my mics but I like Fatheads better for its smaller form factor.

Perfect, works as described.

I use a TC Helicon harmonizer and my dynamic mic wasn't pushing it very hard. I actually had to turn the input gain to max. Once I put the FetHead on my mic I got plenty of signal to my Harmonizer and actually had to turn down my preamps in that signal. Thanks Triton!

LowPo and Loud also!!!

It makes my Shure MV7 LOUD!!! I love how the TRITON AUDIO FetHead has visually low profile but it also make the sound GREAT. I could turn the gain from 35 down to 17 and my voice is clear and sharp. Money well spent.

sound quality vs dc blocker

By kishore

AFTER numerous tests, with below components, below is our opinion on Triton Audio SOUND comparisons of : DC blocker vs FETHEAD for ribbons and dynamics. used : mogami 2534 XLR cable set made by MIT tokyo japan tascam dp 24 with sandisk extreme pro 32 GB golden age project R1 mk2 ribbon mic NOTE THAT : DC block is NECESSARY as INsurance against accidental ? hitting of 48vdc to ON position for sensitive ribbons, dyn. mics. FETHEAD has within it, DC Blocking function as well as amplification for ribbons, and other low level mics. this make it useful for getting better SIGNAL to noise ratio, giving less noise headaches later in mixing / mastering. CONCLUSIONS: 1 /// for instrumentals, best to use DC Block, and make sure the mixer / recorder 48v = OFF position. pre amp gain level on dp24 had to be 8 am to 12 noon level. IF YOU RECORD VOCALS, pre amp gain level on dp24 had to be about 1pm - 2pm level. IF YOU MAKE 48v = ON, you will have gradual loss of low frequencies below 100 Hz....this is how DC blocker works. this is VERY AUDIBLE. 2// if you dont mind changing your R1 mk2 ribbon sound character, and your vocal signal is really low, you have no choice but to use extra clean pre amps or use FEtHEAD... for Vocals, we set pre amp gain level on dp24 had to be about 7am to 9am level. you will need the DC blocker as insurance for life insurance for your sensitive ribbons and dynamics, such as EV re20, EV re320 etc.

When using a FetHead with phantom power can it be left in a constant on condition 24 hours and seven days a week? Is this advisable?

What is this pre-amp's input impedance? Most ribbon mics like to see 600-1200 Ohms.
Asked by: Peter C
Philosophy:FetHead is a low-noise, high quality, in-line microphone preamplifier. It provides improved sound for Ribbon and Dynamic 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:In short, we noticed an improvement on all tested microphones. A Shure SM57 for instance, sounds more responsive over a broader frequency range. When mated with a high-end dynamic microphone like a Sennheiser MD441, or Shure SM7 FetHead really shines. Ribbon microphones benefit greatly too because of a much better impedance match, which lessens the load on the microphone, giving it better transient response characteristics. FetHeads high quality, low noise signal amplification also extends the usable range of a ribbon microphone, making it more suitable for recording softer passages.Protects the microphone: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. All of the specs currently published:Features: Ultra low noise Class A JFet amplifier 27dB amplification (@3 KOhm load) Double single ended amplifier topology 4 matched jFets Shielded enclosure Z-in 22k 24-48 v phantom power

Electret Microphones. Will this TRITON FetHead Regular Preamp with with electret microphones?
Asked by: Sam C.
The standard Triton FetHead does not allow for the passing through of phantom power. The TRITON AUDIO FetHead PHANTOM In-Line Microphone Preamp B&H # TRFETHDPHNTM will provide phantom power to your electret mic.

I am considering to order a FetHead for my dynamic mic and wondering if there will be any sound or gain difference between 1) when plugging the FetHead into my mixer/recorder(Zoom F4) first and then plugging the XLR cable to the mic and 2) when plugging the cable into my Zoom F4 first and then plugging the FetHead into my mic? I am not sure if plugging the FetHead into the mixer/recorder first is even possible or not because all the YouTube reviewers use their FetHeads directly on their mics.
Asked by: Seungmin
As long as your preamp can provide phantom power and the cable length is not more than 10 feet you should be ok. Only problem of doing this is you may run the risk of amplifying noise picked up on the cable along with what your mic produces in sound. Try to keep the FETHEAD as close to the microphone as possible and by all means keep the FETHEAD away from any strong radio frequency fields such as high power UHF/VHF transmitter of low frequency ham radio transmitters. Nearby radio frequency energy near the FETHEAD tends to clip voice peaks.

Can this be used with an unbalanced stereo mic? Considering purchasing this to shield my AT2022 from phantom power but that mic outputs stereo on XLR.
Asked by: R. D. J.
sorry can't help with that one - i don't have a stereo mic so wouldn't know. fethead works great with my ribbon & SM7 though. try manufacturers (Triton Audio). good luck!

Is the the regular version the correct one to use with an h4n and rode ntg2 combo?
Asked by: blk5348
The regular version does not pass phantom power to the microphone, so ditto what the other folks say about using batteries to power the mic

Will the Triton Audio FetHead In-Line Microphone Preamp work with the Sony ECM-44B - Omnidirectional Lavalier Microphone?
Asked by: Daniel
The Sony ECM-44B is a condenser but can't be phantom powered. The ECM-44B requires an internal AA battery thus the FetHead Regular will work fine. If you want to use an ECM-55B or ECM-77B you'll need the FetHead Phantom unless you want to locally power the mic with an AA battery. Once locally powered, the mic will behave like a standard dynamic mic.

Plan on using this product with my Rode NTG2 and dr-40. which version do i buy?
Asked by: Anonymous
I do all of my low end noise removal with SoundSoap or Izotope RX5. I would go with the version without the high pass filter. If you are using a ribbon mic that requires you to use a lot of gain, then the version with the high pass filter would probably serve you well.
