MA412AS Preamplifier
2025-04-17
MA412AS is a
dedicated DC power supply preamplifier developed by BSWA, which is suitable for
MP series 1/4-inch pre-polarized microphones.
The main function of the preamplifier is
impedance change, since the output impedance of the microphone is above GΩ, it
cannot be directly connected to the common data acquisition equipment. The high
input impedance and low output impedance of the preamplifier can reduce the
output impedance of the microphone to less than 100 Ω.
MA412AS does
not provide polarization voltage, so it is only applicable to pre-polarized
microphones. It powered by single or dual DC power supply, with rugged
stainless steel housing and mounting lugs for easy attachment to other
equipment, making it suitable for harsh applications.
MA412AS is
designed for direct cable output for user-definable cable length and output
connector.
