## Description

Buy Triton Audio FetHead in-Line Microphone Preamp: Preamps - desertcart.com ✓ FREE DELIVERY possible on eligible purchases

Review: Silent, Solid, and Truly Professional Inline Gain - Design & Build Quality 🧰 The FetHead is a compact and beautifully machined inline preamp that looks and feels like proper stage hardware, not a gimmick add-on. The steel body is solid and well-finished, with precisely fitted XLR connectors that click in snugly. The labeling is minimal and professional — this feels like a tool made for daily use, not a studio toy. The internal shielding is clearly doing its job, as there’s no detectable hum or interference even when plugged directly into a noisy interface chain. Ease of Use ⚙️ Using the FetHead is as straightforward as it gets — just insert it between the mic and the preamp, and you’re done. There are no switches, no power supply, and no fuss. It runs on phantom power from the interface or mixer, yet doesn’t pass it to the mic, so it’s fully safe for dynamic and ribbon microphones. The small size makes it easy to leave it permanently attached without straining connectors or interfering with stands. Performance in Real Life 🎙️ Noise performance is astonishing. With the preamp gain maxed out but no mic connected, the FetHead remains completely silent — no hiss, no hum, no trace of circuit noise. In a real setup with an AKG D5 dynamic mic, the self-noise floor sits below –80 dB, which is far beyond what most interfaces can measure accurately. The gain boost is clean and transparent, adding presence and clarity without changing tone or adding harshness. On stage, it behaves predictably and never overloads the input; in the studio, it makes low-output dynamics sound like they’ve come alive. Notable Issues ⚠️ None in practice. The only “limitation,” if one has to find it, is that the FetHead is a fixed-gain device — you don’t control the amount of amplification — but that’s part of its simplicity and reliability. Final Verdict 🔑 The Triton Audio FetHead is one of those rare tools that just disappear into the signal chain because they do their job flawlessly. It’s quiet, strong, compact, and built like it belongs on a professional stage or broadcast desk. For dynamic and ribbon microphones, it’s a true plug-and-forget solution that delivers a clean, silent signal boost every time. Absolutely recommended for anyone who values precision and silence over marketing fluff.
Review: Made my NTG-2 usable! - If you have a mic with a high noise floor (sounds like hiss when the gain is turned up), this is your solution. I've had a Rode NTG-2 which is a notoriously weak condenser mic that I've never been happy with. I bought a Tascam DR-60D MkII which still resulted in an unacceptably high noise floor. However, the FetHead completely solved this issue both with the Tascam and recording directly into a C100 Mk2. The NTG-2 now sounds GREAT and this purchase has breathed new life into it. This FetHead requires phantom power but does NOT forward the phantom power, so condenser mics either need to use the phantom version of the FetHead or a battery, if supported. Triton Audio recommends this version with a battery for the NTG-2. The FetHead itself is small and plugs inline with the XLR cable. I really like this form factor as it's very easy to use and doesn't require an additional XLR cable. The quality of the FetHead was bad enough I'm not sure mine is genuine - the logo is off center and the FetHead itself isn't completely straight. It seems to work just fine though. All in all, considering the price and form factor this is a must buy if you need some additional clean gain. If you have hiss, buy this before trying anything else and avoid my mistake of buying increasingly expensive interfaces!

## Questions & Answers

**Q: For some reason this making the noise floor and the mic input louder, any idea why?**
A: The TRITON AUDIO FetHead In-Line Microphone Preamp boosts a microphone's output by over 20 dB (with 48 V phantom power applied). It is designed to help ribbon microphones and other low output mics provide sufficient input levels to your mixer or external mic preamp to keep from the necessity of running them at a too high -- thus noisy -- level. For instance, in one of my setups I use a FetHead in line with a Shure SM7B mic and feed them into a Focusrite Scarlett Solo USB Audio Interface with built-in mic preamp. Without the FetHead, I must crank the audio interface preamp input gain wide open to obtain sufficient recording levels. This produces objectionable noise. With theFetHead in line, only half gain is needed from the preamp and practically no noise is generated. The same holds true when I am using one of my ribbon mics. Turning the preamp or mixer's mic input gain down when using the FetHead (which should be thought of as an "auxiliary" preamp), should solve your problem. It sounds as if your FetHead is working as designed.

**Q: Why does it say it’s for condenser microphones in the description but shows dynamic mics in the pictures?**
A: The Fethead Phantom is for condenser microphones because it supplies phantom power to condenser mics that need it. The other version of this product, just a plain Fethead, does not supply 48 V. That is the version you would use for dynamic or ribbon mics. Though it may be possible for some microphones to use either one, I would not recommend it. Use the version of the Fethead that is intended for your particular type of microphone, condenser or dynamic. I have both, and I recommend both of them for the appropriate type of microphone. They do a really good job of adding gain with very little to no noise.

**Q: I have a scarlett 2i2 3rd gen. should i use the phantom power with the microphone and the pre-amp? microphone: shure sm7b**
A: When using the Triton FetHead inline preamp to boost the low output from a Shure SM7b (or other dynamic mic), the Focusrite Scarlett 2i2's phantom power should be turned ON. This is to power the FetHead. The device will not operate without the phantom power. The FetHead, though, blocks the voltage from the microphone itself to avoid damage to certain microphones (some ribbon mics, for instance).  Condenser mics (primarily studio mics) require phantom power themselves, but normally do not require supplemental preamps such as the FetHead or Cloudlifter.

**Q: Fethead safe for use with an R88 Ribbon?**
A: I use mine to power 2 Ribbon mics with no problems.   The Fethead is Phantom powered from your interface/preamp so be sure to have Phantom power off when connecting and disconnecting.
