Functional features


1. Adopt the modular clasp structure to support the superposition of functional modules. Different modules can be selected according to the user's demands for functional realization;

2. The connection between the modules is carried out through the low impedance 12K gold connector, the single needle through the current up to 2 amperes

3. the use of FCS communication technology, easy to achieve convenient management and flexible control

4. the box adopts a unique sound surface sound structure design, sound direct Angle >
240°, the sound source coverage area is not less than 100m², the recommended use area of 80m²

5. Adopts 3 class D amplifiers with independent configuration and preprocessing to complement each other with the same cavity sound source, which can effectively improve sound efficiency and improve sound quality.

6. Built-in network module, access to switch network, provide data link information upload.

7. The system uses microcomputer technology to cooperate with FCS to complete a variety of complex logic, and provides priority processing authority for manual priority, automatic priority and network priority in three different working environments.

8. the box can be extended access to all modules in the FCS protocol: with one division and one mike module, to achieve at least 2 microphone wireless sound amplification and 1 Bluetooth two-way audio amplification, support echo cancellation;
With network audio decoding function, to achieve the classroom IP network broadcast function, support listening broadcast double backup function;
With ZigBee IoT control function, it provides the classroom with IoT gate;
With the docking function, support the wireless expansion of the number of 1 to 4 speakers, to meet the needs of large multimedia classroom sound amplification, to meet the needs of 300 square sound amplification;
Expansible environmental monitoring module, to achieve real-time monitoring of classroom air quality, temperature and humidity, illumination and other environmental data;
Extensible wireless projection module to achieve the application of wireless projection of computers, mobile phones and tablets in the classroom;
Extend all functional modules that support the FCS protocol.

9. Built-in IC card information backup card slot, support all function modules of the speaker configuration information backup and automatic restoration of configuration information;
