1/2' ICP® Preamplifier
The ICP® Preamplifier Type MA211 is specially developed for 1/2" prepolarized microphones. It is a high-performance preamplifier with low inherent noise and high input impedance. The excellent frequency response ensures that the microphone with MA211 complies with IEC 651 Type I requirements. MA211 preamplifier can be directly connected to any ICP® inputs.
MA211 is used for general purposes of sound measurements. Comparing with traditional microphones preamplifiers, the advantages of the ICP® type are low cost, easy to use and long cable option. The dynamic range can be achieved with MP201 from 15 dBA to 130 dBA. (The low sensitivity microphone is required for noise level exceeded 130dBA)
