Mic Preamp with High Pass Filter
Triton Audio - 'FetHead Filter'

For Ribbon & Dynamic Microphones
Triton Audio’s ‘FetHead Filter’ is just like a regular FetHead, but instead features a 6dB/octave high pass filter with a corner frequency of 220Hz. FetHead Filter was specifically designed for mics which can often exhibit an excessive proximity effect / low frequency response, such as long motor ribbon mics. The components which make up the filter, aren’t directly in the signal path but are instead applied to the components which set the gain of FetHead Filters amplifier, therefore making it frequency dependent.
Protects the microphoneSome ribbon mics don’t take too kindly to phantom power. For this reason, FetHead’s circuitry uses 48V phantom power, but shields it from the mic, ensuring your mic is fully protected.
