The system’s key advantages include its advanced directional pickup technology, which uses 8 microphone arrays to focus on the lecturer’s voice within an 8-meter radius while suppressing sounds from other directions, effectively solving the problem of background noise interference in lecture halls. It integrates active noise cancellation technology that can identify and eliminate repetitive background noise such as air conditioning hum and projector fan noise, ensuring clear audio recording and transmission. The professional audio management platform supports real-time audio monitoring, remote parameter adjustment, and automatic lecture recording, with the ability to save recordings in high-resolution WAV or FLAC formats. The system also supports seamless integration with classroom management systems and online learning platforms, allowing recorded lectures to be uploaded directly to learning management systems (LMS) for student access. Additionally, its ceiling-mounted installation design saves desktop space and ensures uniform audio coverage across all seating zones, while the desktop microphone option provides flexibility for guest speakers or panel discussions.
The system features 8 ceiling-mounted microphone arrays, each with an 8-meter directional pickup radius and a frequency response range of 50Hz-18kHz. The audio sampling rate reaches 96kHz/24-bit, ensuring high-fidelity sound reproduction and recording quality. The maximum sound pressure level of the main speakers is 115dB, providing clear audio coverage for up to 500 people in a 500-square-meter lecture hall. The main control unit supports XLR, USB-C, and Ethernet interfaces, allowing for connection to microphones, speakers, and network systems. The professional audio management platform is compatible with Windows and macOS operating systems, supporting real-time audio monitoring, automatic recording, and audio editing functions. Each ceiling-mounted microphone array measures 150mm (D) × 50mm (H) and weighs 2kg, with a power consumption of 10W per array. The main control unit measures 400mm (W) × 250mm (D) × 80mm (H) and weighs 10kg, with a power consumption of 300W and support for AC 100-240V universal voltage. The system also includes 2 desktop wireless microphones with a 50-meter transmission range and a 10-hour battery life.
This system is ideally suited for university lecture halls, research institution auditoriums, training centers, and corporate training facilities that host academic lectures, seminars, workshops, and training events. Typical application scenarios include: recording university lectures for online learning platforms, where the noise-canceling technology ensures clear audio quality for remote students; hosting academic seminars with multiple speakers, where the system’s multiple microphone arrays can capture each speaker’s voice clearly; conducting corporate training events, where the system can record training sessions for later review by employees; and organizing panel discussions, where the desktop wireless microphones allow panelists to speak freely without being restricted by wires. It is also suitable for use in research institutions that host international academic conferences, where the system’s high-resolution audio recording ensures accurate capture of research presentations and discussions. The system’s seamless integration with LMS platforms and professional audio management features make it an essential tool for academic institutions and corporate training facilities looking to enhance their audio recording and transmission capabilities.
