The 1/2” measuring microphone preamplifier type MV 220.S P48 is a high-impedance transducer for 1/2" prepolarized measuring microphone capsules. It enables direct powering of the measuring microphone capsules by balanced inputs with 48 volts phantom powering usual for studio technique.

Nearly the entire dynamic range of the measuring microphone capsules can be used. Commentary DAT recorder with phantom powering without signal condtioner can be used as data memory for measuring technique applications. Other possible applications are loudspeaker measurements and set up of acoustic equipment.

The Adaptor A 63.1 allows 1” prepolarized measuring microphone capsules to be mounted on the 1/2” preamplifier and the Adaptor A 67 makes the same for the 1/4” prepolarized measuring microphone capsules possible. The thread of the preamplifier confirms to the international standard according to IEC 61094.

The measuring microphone preamplifier MV 220.S P48 is designed for sound level meters of IEC Type 1 according to IEC 61672.
