ICP® Microphone Preamplifiers and Filter
November 1, 2003, Provo, UT - Larson Davis introduces two microphone preamplifiers. Models PRM426 and PRM422 are low noise, general purpose prepolarized microphone preamplifiers powered by any constant current (2 to 20 mA) ICP® sensor power supply.
The PRM426 and PRM422 accept 1/2 inch and l/4 inch microphones respectively, and both models are compatible with TEDS standard IEEE P1451.4 as a microphone preamplifier, or as an integrated microphone/preamplifier when paired with a precision microphone. In-Line ICP® A-Weighting filter is available for filtering the output signal from Model PRM426. All models feature small size, and rugged, stainless steel construction, and have a wide frequency bandwidth and large dynamic range.
