    600 040 070 - Overview

    The M4261 is a calibrated, omni-directional class 2 measurement microphone running from 48V Phantom power. It shows excellent linearity over a wide dynamic range from 27 dB SPL up to 144 dB SPL.

    The microphones are 48V phantom powered and include an electronic data sheet. The Automated Sensor Detection (ASD) of the XL2 Analyzer automatically reads this data, i.e. the microphone model and calibration data. This promotes faster setup and ensures accurate measurements.

    The microphone bodies contain the preamplifier. They combine high dynamic range and wide frequency range with low noise. The M4261 microphones connect via the ASD Cable to the XL2 Audio and Acoustic Analyzer, e.g. for measurements at remote locations or to reduce acoustic reflections.
