Overview
An in-line metal booster, this Klark Teknik unit goes between a dynamic microphone and the next XLR input to add clean gain. It is powered by phantom power and has a mini form factor. The description calls it a compact dynamic microphone booster with a quality preamp.
Extra clean gain from a small body is the reason to add it for quiet dynamic microphones into interfaces with weak preamps. The limit is the supply: a source without it will not run the unit.
Who it's for
Podcasters and streamers pairing a low-output dynamic microphone with a modest interface will use the extra boost. Anyone with condenser microphones or no phantom power should skip it.
Pros and cons
- Adds boost to dynamic microphones
- Compact metal body
- XLR input and output
- Phantom powered, no battery
- Needs phantom power
- Single channel only
- Gain amount is fixed per listing
Performance notes
The preamp adds clean gain before the signal reaches the next device, which lowers the noise from a weak input stage. Real benefit depends on the microphone output and the interface you use. The listed signal to noise ratio is the figure to check against your setup.
