Flexible and Efficient Operation & Control: Features a 4.3″ full-color display + multifunctional flywheel button, supporting wireless access and debugging via PC/mobile/tablet. Offers 5 speaking modes including restricted speaking and chairperson priority, enabling sign-in voting without software. Customizable speaker unit roles, names, and IDs meet diverse meeting management needs.
Superior Audio and Video Performance: 48kHz lossless sampling with <10ms low-latency transmission. Supports individual/group adjustment of speaker unit volume, AGC, EQ, and other parameters. Compatible with three camera protocols, enabling preset position configuration and seamless matrix switching. Simultaneously supports Bluetooth audio input/output for versatile applications including sound reinforcement and recording.
Key Features:
1. 4.3″ full-color display with a clean, intuitive UI interface. Multi-function joystick key enables rapid operation and precise adjustment of every system parameter;
2. Supports digital transmission via hand-in-hand ring networks, accommodating two independent ring networks to meet diverse networking requirements;
3. Capable of initiating sign-in and voting functions independently of conference management software;
4. Speaking Functions:
Limited Speaking Mode: Maximum of 10 speakers allowed;
Chair Priority Mode: Only the chair unit can speak;
First-In-First-Out Mode: When the maximum number of speakers is reached, the last activated speaking unit replaces the first activated unit. The chair unit is exempt from this rule;
Request-to-Speak Mode: Delegate units send requests to the chair unit via the talk button before speaking. Approval from the chair unit is required before speaking. The chair unit display shows a queue list of delegate units;
Time-Limited Speaking Mode: By setting a speaking time limit, delegate units must complete their remarks within the specified time. Upon reaching the set time, the delegate unit’s speaking function automatically shuts off.
5. Audio parameters (input volume, AGC, EQ, etc.) for each wired/wireless microphone unit can be adjusted individually or collectively.
6. Customizable role attributes (Delegate Unit, Chair Unit, Moderator), user names, and microphone IDs for each microphone unit.
7. Independent camera preset position adjustment for any wired/wireless microphone unit, with seamless multi-camera switching and tracking via video matrix integration.
8. Supports wireless access via PC, mobile, or tablet devices to the system hotspot, enabling real-time adjustment and debugging through web pages and UI interfaces;
9. Supports Pelco_D, Pelco_P, and VISCA camera communication protocols for strong compatibility;
10. Built-in RS232 control interface connects to central control systems or directly controls external video switching matrices, with customizable control commands for different matrix brands;
11. Supports real-time USB recording with maximum 64GB FAT-formatted USB drives;
12. Hot-swappable seat microphones with plug-and-play functionality requiring no configuration;
13. Supports power-on self-test and automatic diagnostics with fault cause indication;
14. Supports balanced output via XLR connectors or 3-pin terminals, and unbalanced output via RCA connectors to meet local amplification, meeting recording, and remote video conferencing needs;
15. Supports Bluetooth audio input/output for connecting mobile phones or computers. Enables software-based video conferencing or temporary phone call integration.
16. Utilizes 48K Hz audio sampling between host and microphone for lossless transmission. < 10ms latency ensures consistent audio quality regardless of network cable length.
