Convenient in-line design
Thanks to its convenient in-line design, FetHead Filter is a breeze to use. It latches effortlessly onto any XLR-equipped microphone, or you can place it anywhere between your mic and preamplifier or console. Beyond that, FetHead Filter's electronics are housed in a durable metal chassis with balanced I/O. Here at Sweetwater, we've found this compact in-line preamp to be rugged enough for home, studio, and stage alike.


27dB of juice plus a highpass filter
With 27dB of clean, FET-fueled gain on tap, Triton Audio FetHead Filter will level up the performance of any mic you plug into it. It can take a 57-style dynamic mic to an entirely new tier of performance, infusing it with agile responsiveness over a wider frequency range, while lending a studio-level character to high-end dynamic and broadcast mics. FetHead Filter reduces the impedance load on ribbon microphones, granting them enhanced transient response and an extended usable range. To top it off, FetHead Filter includes a 6dB/octave highpass filter with a 220Hz cutoff — exactly what you need to tame unwanted low-frequency rumble and excessive proximity effect.
Protects your fragile ribbon microphones
Have you ever fried a vintage ribbon mic with phantom power? If not, count yourself lucky — it's a traumatic experience. FetHead Filter safeguards against this unfortunate situation. While it employs phantom power to power its circuitry, it doesn't pass phantom power to your microphones. It's the ideal insurance policy for your fragile ribbon mics.
