digital wired hand-in-hand daisy chain discussing conference system host

ZR-6802M

Equipped with a 1.8-inch color display that shows the following information: number of chairmen, number of VIP units, number of delegate units, number of active speakers, and conference mode. Conference functions are controlled via six function buttons. The rear panel features a power switch. After the host is powered on, long-press the ESC key for 5 seconds to unlock the panel.
Five conference modes available: Chairman Only, First-In-First-Out (FIFO), Last-In-First-Out (LIFO), Limited Mode, and All Open Mode.
Number of simultaneous speakers: Except in All Open Mode, the number of concurrent speakers can be set from 1 to 12.
Chairman priority function: The chairman priority key can be set to Off or Mute. Supports turning off delegate units by pressing the button or muting delegate units by pressing and holding the button (automatically restores when the key is released).
Restricted speaking settings: Supports linkage between speech restriction and voice-activation mode. After the microphone is activated by voice, it can be set to automatically turn off after a maximum of 3 minutes without speech.
Timed speaking: Speaking duration can be set up to a maximum of 99 minutes; the microphone automatically turns off when the time expires.
Volume settings: Includes one balanced output and one unbalanced output (2 audio channels in total). Each channel supports 0–20 level volume adjustment.
Automatic addressing: After microphones are connected to the host, addresses can be reassigned or new units can be added. Adding new microphones midway will not affect units that have already been addressed.
Language settings: Supports two system languages — Chinese and English.
Key tone: Button operation prompt sound can be turned on or off.
Voice-activated microphone: Supports 10-level sensitivity adjustment and can work in combination with any of the 5 conference modes. Sensitivity can be adjusted according to the on-site environment to achieve the best voice-activation performance.
System version: Allows viewing of the current host version information.
Features 4 channels of 8-core conference microphone input interfaces. Each channel supports up to 40 units and can be expanded with expander to connect more units.
Equipped with 1 XLR balanced audio output interface, 1 × 6.35 mm unbalanced audio output interface, and 1 USB interface for PC software configuration, allowing connection to a PC for system configuration.
Supports ring-type loop hand-in-hand (daisy-chain) connection. Even if one network cable is disconnected or a unit fails, the conference system can continue to operate normally.
Supports customized AI noise reduction. Equipped with a new-generation intelligent noise reduction module and audio processing engine, it utilizes deep learning algorithms for real-time noise reduction, echo suppression, and howling prevention. It can filter out environmental noises such as air conditioning, keyboard typing, fans, clapping, and page turning, accurately identify human voices, ensure clear audio pickup in complex environments, and improve overall conference sound quality and communication effectiveness.
