PMM47

The mini microphones is specially designed for low noise level instrument application. It has PMM46 & 47 a clean, transparent and well balanced sound. It’s ideal for general recordings of soloists and ensembles. It’s a prepolarized ½” diameter condenser microphone which is power from standard 48VDC phantom power. It is made of Ni-Cu alloy to ensure excellent sensitivity and frequency response stability and very wide operating temperature range, low ambient-temperature coefficient. The frequency response is very smooth from 20Hz to 20KHz (only 2dB tolerance). The microphones has a very low equivalent noise 17dB(A), a very high sound pressure level 146dB(peak), that means very high dynamic range 129dB, and a high sensitivity 100mV/pa(-20dB re 1V/pa), balanced output. It is an obvious choice for low noise recordings. The PMM46 & 47 is complied with the specification of IEC651 type1.
