Audio-Technica Power Module|In-line type power module, phantom power only

The AT8538 is an in-line power module designed for use with selected Audio‑Technica electret condenser microphones. It allows compatible microphones to operate using standard phantom power from professional audio equipment such as mixers, audio interfaces, or recording systems.

The module converts phantom power into the appropriate voltage required by the microphone’s internal circuitry and provides a balanced XLR output for stable, professional audio connections. Its compact in-line design makes it easy to integrate into live sound, broadcast, and recording setups.
