1/4” Free-field iTEDS enabled microphone and preamplifier set

1/4” Free-field iTEDS enabled microphone and preamplifier set

The Endevco model EM46BE from Meggitt Sensing Systems is a combined 1/4” free-field pressure microphone and iTEDS-enabled preamplifier set (per IEEE 1451.4), designed for general purpose and larger channel count precision acoustic measurements.


The model EM46BE comes in a preassembled, pre-calibrated kit, consisting of the model EM40BE ¼” prepolarized free-field microphone and the model EM26CB ¼” Isotron preamplifier with Microdot coaxial connector, both constructed of stainless steel for high durability. Units are assembled in a clean room environment to avoid contamination of the contacts and are calibrated together to form a reliable acoustic measurement system. These combined units are fully repairable.

With a frequency response from 10Hz to 40kHz (±1 dB) and a wide dynamic range of 40dBA to 160dB (re. 20 μPa), the Endevco model EM46BE is designed according to guidelines set forth by IEC 61094 Class 1, the highest industry standards for precision acoustic product reliability. Incorporation of iTEDS technology allows for the microphone and preamplifier to be recognized by any smart-transducer compatible input module. When connected, the analyzer will derive data such as microphone type, serial number and sensitivity, which can be read by the application software for simplified test setups. Units are designed to operate from any industry standard 2-20 mA power supply.
