Broadcast Core Board
A highly integrated core solution for public broadcasting, emergency broadcasting, and intercom broadcasting, which provides competitive advantages in terms of audio performance, scenario adaptation, and mass production costs.
Features
These chips are equipped with professional audio power amplifier technology and serve as benchmark devices in the security broadcasting industry. They offer high-fidelity audio output, with a maximum power capacity that can drive 60W speakersStronger driving power, lower distortion, and maximum anti-howling capability, perfectly suited for outdoor high-volume broadcasting scenariosFull interface integration: MIC input, SPK amplifier output, network interface, 4G interface, alarm input/output, reset button, network indicator light, alarm button indicator light. Covers all functions of broadcasting, intercom, and alarm in one solution, without the need for additional expansion boards.Built-in echo cancellation and AI noise reduction, effectively solving industry issues such as broadcast feedback, noise, and echoes. Simplified algorithms compared to competitors, offering superior sound quality and stability.Amplifier drive: Supports fixed-impedance/fixed-voltage speaker drives, compatible with indoor ceiling speakers, outdoor sound columns, and horn speakers to meet various volume requirements.Supports SIP protocol for two-way voice intercom, enabling real-time communication between terminals and the management center, as well as between terminals themselves.Supports OEM/ODM firmware customization, compatible with customer-specific broadcasting platforms, national standard platforms, and third-party monitoring systems (ONVIF).Supports TCP/IP network broadcasting, scheduled broadcasting, zone-specific broadcasting, real-time broadcasting, and alarm broadcasting. Can be integrated with emergency broadcasting systems, suitable for public broadcasting scenarios such as campuses, parks, scenic areas, and communities.
