MA-PVA

Beyerdynamic MA‑PVA – Phantom Power Adapter for TG‑Pinout Microphones

The Beyerdynamic MA‑PVA is a compact phantom‑power adapter designed for powering Beyerdynamic headset, lavalier and miniature condenser microphones that use the TG 4‑pin mini‑XLR pinout. It converts standard 48 V / 24 V / 12 V phantom power from any balanced XLR microphone input into the AB powering required by electret capsules.

With its rugged metal housing and integrated belt clip, the MA‑PVA is ideal for theatre, broadcast, presentations, ENG, and any application where body‑worn microphones must be used with professional mixers, preamps or wireless systems that provide standard phantom power.
