Chkenono FC-1 Inline Microphone Preamp Gain Booster

The Chkenono FC-1 occupies a narrow but genuinely useful niche. It is an inline preamp aimed squarely at owners of low-output XLR microphones — the broadcast dynamics and passive ribbons that demand far more gain than many affordable interfaces can supply cleanly. By adding up to 25 dB of active gain right at the source, the FC-1 lets you keep your interface preamp in its quieter operating range rather than cranked near maximum. For podcasters and voice-over artists chasing a full, low-noise signal from a microphone such as the SM7B or RE20, that is precisely the point.

Practical ownership is refreshingly uncomplicated. The unit draws 48V phantom power from a compatible interface, mixer or external preamp, so there is nothing to charge and no wall wart to find room for. Crucially, that phantom voltage powers only the FC-1's internal circuit and is not passed along to the microphone, which keeps ribbon and dynamic mics out of harm's way. Connection follows a simple chain: mic into the input, output into your XLR interface or mixer, then flip on 48V. The compact metal housing feels built for the road as much as the desk, small enough to leave permanently inline or drop into a bag for location work.

The trade-offs are clear and honestly bounded. This is an XLR-only device with no USB compatibility, and it depends on a phantom-power source to function at all. There is no variable gain knob here — you get a fixed active boost rather than a dial to fine-tune. For its intended audience, though, those constraints are easy to accept in exchange for a straightforward, no-fuss way to make a quiet microphone sing.
