Established Measurement Microphone Family Expands

Audio Precision expands its line of measurement microphones with the introduction of the 376M03, a calibrated microphone system combining a 0.5-inch microphone cartridge with a 426M16 phantom-powered preamplifier. The new preamplifier combines the precision of calibrated, standardized measurement microphones with the convenience of ubiquitous mic accessories offering phantom power, balanced connections noise, and connectivity via common XLR cables.

 

The preamplifier, purchased individually or as part of the 376M03 microphone system, is delivered with adapters allowing it to mount either 0.5-in. and 0.25-in. standard IEC 61094-4 pre-polarized microphone cartridges. Depending upon the AP microphone cartridge configured with the 426M16, mic system performance offers a noise floor as low as 15.5 dB(A), or frequency response to 100 kHz. The mic cartridges use a stainless alloy which remains stable during temperature, humidity and atmospheric pressure changes, yielding more accurate test results. Each mic is delivered with its own certificate of calibration.
