2026-05-12BSWA MK Series Microphones: Upgraded for New Quality Productivity
BSWA MK Series Microphones deliver IEC 61672 Class 1 accuracy, wider dynamic range, better SNR, and 200V polarization for long‑term stable high‑precision acoustic measurement. Engineered for professional acoustic testing, the series sets a new standard for reliability and performance in critical measurement environments1.
Overview & New Quality Productivity Positioning
The MK Series represents a technological breakthrough for new quality productivity in high‑end acoustic measurement. It integrates upgraded dynamic performance, signal-to-noise ratio (SNR), and industrial-grade stability to meet the strictest requirements for precision, efficiency, and long‑term reliability in acoustic testing applications.
Core Advantages of MK201 1/2” Free‑Field Microphone
Upgraded Dynamics & SNR: Dynamic range increased by 8–10 dB vs. the MPA series; captures both faint environmental noise and high sound pressure levels with exceptional accuracy.
200V Polarization for Superior Stability: Classic 200V polarization design eliminates electret and charged backplate components, preventing performance aging and decay over extended use.
IEC 61672 Class 1 Accuracy: Delivers full‑band high‑precision measurement with wide frequency response and ultra‑low distortion for laboratory and industrial compliance testing.
Professional Compatibility & TEDS: Fully compatible with dedicated MV preamps and supports intelligent TEDS for seamless plug‑and‑play system integration and automated device recognition.
