Dual‑channel desktop speaking microphone

The PRO-2T2NH desktop speech microphone features a dignified and aesthetically pleasing design, incorporating two custom‑designed dual‑diaphragm condenser microphones arranged in a horizontal array with gold‑plated diaphragms. The entire unit employs horizontal array technology to precisely control the horizontal pickup pattern, effectively minimizing environmental interference and acoustic feedback. A meticulously engineered etched grille, combined with advanced interference‑correction techniques, ensures crystal‑clear capture of every sonic nuance. A uniquely shaped capsule chamber, paired with sophisticated pickup‑alignment algorithms, faithfully reproduces even the subtlest details of sound. Specially designed shielding circuitry and an integrally molded zinc‑alloy housing efficiently suppress electromagnetic interference, delivering clean, pristine audio that meets the demanding requirements of high‑quality conference sound reinforcement. The microphone’s overall form exudes cohesion and harmony, its design inspired by the traditional Chinese concept of “heaven round, earth square,” highlighting the essence of Chinese cultural heritage and conveying profound symbolic meaning.
