Specifications

The PLACID PMNP21T is a Measurement microphone adopts IEPE power supply mode, without polarization voltage, and complies with IEC61672 Type 1. It has embedded TEDS technology, it uses TEDS technology (Transducer Electronic Data Sheet) to store the microphone sensitivity information on a chip inside the preamplifier. (IEEE1451).

It can be connected with IEPE power supply signal conditioner, data collector, sound level meter and other testing equipment for precise acoustic measurement, with good phase consistency, suitable for forming a multi-channel measurement system.
The PLACID PMNP21T measurement microphone includes PLACID PNP21T preamplifier and PLACID PMP21 1/2″ high-quality prepolarized free field microphone capsule. The PLACID PNP21T preamplifier has built-in TEDS function, supporting data acquisition equipment to directly read microphone information, including model, serial number, sensitivity, etc. The shell of the preamplifier is made of stainless steel, which is suitable for acoustic testing requirements in many occasions.
The frequency response index of PLACID PMNP21T is strictly controlled according to the IEC standard. All microphones have passed the rigorous environmental aging test, making them have the advantages of wide frequency range, wide dynamic range, flat frequency response, long time stability, etc.

Standards

Features

Suitable for precise acoustic test
Frequency range covers most test requirements
Built-in TEDS function
Compact structure and small volume

Design

All PLACID ICCP microphone preamplifiers are designed for ¼”, ½” and 1” condenser microphones. The preamplifiers are optimized to have a flat frequency response which will ensure high quality acoustic measurements.

Self Noise

The electrical circuit has especially been designed to ensure a low self-noise level which typically be much lower than the self-noise of the microphone cartridge.

PLACID PMNP21T

The frequency response index of PLACID PMNP21T is strictly controlled according to the IEC standard. All microphones have passed the rigorous environmental aging test, making them have the advantages of wide frequency range, wide dynamic range, flat frequency response, long time stability, etc.
