Microphone Preamplifiers feature rugged SS construction.

Models PRM426 and PRM422 are low noise, general-purpose, prepolarized microphone preamplifiers powered by 2-20 mA, constant current, ICP® sensor power supply. They accept Â-½ and ¼ in. microphones, respectively, and are compatible with TEDS standard IEEE P1451.4 as preamplifier, or as integrated microphone/preamplifier when paired with precision microphone. In-Line ICP®...
