1/2” preamplifier MTG MV210 ICP/IEPE
The 1/2” measuring microphone preamplifier type MV 210 is a high-impedance transducer for 1/2" prepolarized measuring microphone capsules.
The electrical connection is via a BNC-cable to the usual current powered measuring channels such as ICP/IEPE. The measuring microphone preamplifier has an integrated memory for microphone identification. Microphone data can be entered and readed by the manufacturer/user by using the memory (IEEE P1451.4 TEDS editor).
We offer adapter for 1” or 1/4" prepolarized measuring microphone capsules to be mounted on the 1/2” preamplifier. The thread of the preamplifier confirms to the international standard according to IEC 61094.
The measuring microphone preamplifier MV 210 is designed for sound level meters of IEC Type 1 according to IEC 61672.
