DETAILS
SPECS

The DSP9422 is a high-performance omnidirectional microphone designed for normal classroom recording and remote interactive applications. With a single DSP9422 offering an 8-meter pickup radius, two units can cover classrooms or conference rooms exceeding 120㎡. Presenters or speakers can speak from any position within a 2 to 8-meter range of the DSP9422 without compromising pickup quality.

The DSP9422 features a large, professional-grade transducer, which maximizes its expansive audio capture plane to pick up a wide range of audio signals with solid, powerful sound. Its unique acoustic chamber design effectively suppresses reverberation caused by extensive coverage, delivering clear, distortion-free sound and true omnidirectional pickup.

In addition, the DSP9422 provides a broad frequency response, ensuring balanced, high-fidelity sound with an excellent listening experience. Utilizing advanced field-effect design technology, the DSP9422 enjoys high sensitivity and exceptionally low noise, achieving an impressive signal-to-noise ratio.

The DSP9422 is widely used in classrooms and conference rooms, setting a benchmark in the industry as an exemplary omnidirectional microphone.
