Overview
Plugging a ribbon or dynamic microphone into this inline preamp raises its signal before it reaches an interface. A Class-A circuit with a transformerless FET design does the work, and a buffer amplifier helps in long cable runs.
The reason to buy is a clean fixed boost for low-output microphones in a slim metal body. The limit is that there is no gain control, and the listing names only passive ribbon and passive dynamic microphones.
Who it's for
People recording vocals or speech with low-output mics, or feeding a long cable run, will notice the boost. Those who want a gain dial, or whose interface cannot send phantom power, should choose another approach.
Pros and cons
- Fixed gain independent of the load
- Transformerless Class-A design
- Slim all-metal housing
- Gold-plated XLR connectors
- No adjustable gain
- Needs phantom power
- Warranty field reads Na
Performance notes
A fixed boost lifts a quiet signal above the interface's own noise floor, which is where the cleaner result comes from. A low output impedance and a buffer stage help the signal travel through longer cables. The preamp relies on supplied phantom power to run.
