A Power Adapter Designed for the Beta Range
This preamplifier serves as an interface between a standard microphone input powered by 48V phantom power and Beta capsules requiring a lower voltage. It allows easy integration of these microphone capsules into a sound reinforcement, live recording, or studio setup without modifying your audio chain or adding dedicated external power supply.
For Whom and For What Uses
Ideal if you use a Beta capsule on a mixing console, stagebox, or audio interface providing 48V. It is intended for sound engineers, musicians, and technicians seeking a simple and reliable solution to properly power the capsule while maintaining standard XLR connectivity on the output side.
48V to 5V Conversion and Signal Transparency
The transformerless circuit is designed to preserve the dynamics and tonal balance of the capsule, with an extended frequency response. The conversion from 48V phantom power to 5V ensures the necessary electrical compatibility while maintaining clean integration within a professional microphone chain.
