The MA5A-mini Array Microphone Subunit is equipped with five high-sensitivity microphone elements, forming a highly sensitive microphone array. When used with the MA5A Adaptive Pickup All-in-One Unit, it extends the pickup range and enhances speech clarity through its core voice correction algorithm.

The MA5A-T System consists of an adaptive pickup and amplification all-in-one unit (multi-directional array microphone), an array microphone subunit, a multi-directional coaxial speaker, and a touch control panel. Teachers can speak without carrying a microphone and move freely within the room while maintaining clear amplified speech. Depending on the classroom size, two to four ceiling-mounted speakers can be installed for optimal sound distribution. The system features intelligent control via a touch panel and includes a USB recording function, allowing teachers to play back class-related recordings, record lessons for students to review at home, or assess their own teaching quality.
