RONDSON Built-in Microphone for Discreet Mounting

Product description

RONDSON Built-in Microphone for Discreet Installation

The PHM 914 W is a professional white built-in microphone from Rondson, designed for discreet sound capture in conference rooms, auditoriums, courtrooms, and interrogation spaces. With a subtle diameter of just 30 mm and a mounting depth of 71 mm, it integrates almost invisibly into tables, lecterns, or ceilings.

Discreet and high-quality performance

The rear-mounted electret capsule (“back-electret”) ensures reliable audio quality. Its unidirectional pickup pattern reduces unwanted room reflections and background noise. The extended frequency range of 20 Hz to 20 kHz delivers natural, clear speech reproduction and captures deep audio content. With a standard sensitivity of –63 dB ±3 dB and balanced 250 Ω impedance, it’s a perfect match for professional amplification systems and audio interfaces.

Thanks to its phantom power requirement of 9–52 V DC, the microphone can be easily integrated into existing audio setups – no additional power supply needed. The male XLR connection allows for compact wiring and simple integration into mixers, DSPs, or amplifiers. The durable plastic housing is designed for long-term use and is ideal for high-traffic professional environments.

With references in high-level institutions such as judicial and government settings, the PHM 914 W is a reliable module for audio systems where discretion and quality are key.
