MPA241 1/2-inch Microphone Set

MPA241 is a combination of MP241 microphone and MA231A preamplifier, which can be separate into MP241 and MA231A according to user’s application.

MP241 is a 1/2-inch free-field microphone, suitable for measurement in free-field and semi free-field without reflection. It is prepolarized microphone without the need for external polarization voltage and suitable for ICCP-powered preamplifier. It is complying with IEC 61094 WS2F standard.

MA231A is a 1/2-inch ICCP-powered preamplifier, suitable for prepolarized microphones.

Optional TEDS is available for most of BSWA preamplifier to support read microphone information directly by data acquisition equipment, including microphone model, serial number, sensitivity, etc. BSWA TEDS microphone supports the IEEE 1451.4 standard. The v0.9 version is used by default to be compatible with more data acquisition equipment. The v1.0 version can also be selected according to user’s requirements.
