gooseneck microphone system digital wired conference system controller for meeting room

ZR-6815M

Equipped with a 1.8-inch color display that shows the following information: number of chairpersons, number of VIPs, number of delegates, number of speakers, and conference mode. Six function keys are used to control conference functions. The rear panel has a power switch.
The host features an automatic lock function. The panel must be unlocked by press and hold the ESC key for 5 seconds.
5 conference modes: Chairman Only, FIFO (First In First Out), LIFO (Last In First Out), Limited Mode, and All Open Mode.
Number of speakers: Except for All Open Mode, all other modes allow setting 1–12 simultaneous speakers.
Chairman priority mode: 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).
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.
Volume settings: Includes 4 audio channels — Line Input, Line Output, Balanced Output, and Unbalanced Output. Each channel supports 0–20 level volume adjustment.
Camera tracking settings can be configured directly via the host display. Supports VISCA, PELCO-P, and PELCO-D protocols. Maximum support for connecting 8 cameras and camera positions are adjustable.
Limited speech settings: Supports linkage between speech restriction and voice-activated mode. After a microphone is voice-activated, it can be set to automatically turn off if there is no voice activity for up to 3 minutes.
Timed speech: Maximum speaking time can be set to 99 minutes; the microphone automatically mutes when time is up.
Key tone: Key operation prompt sound can be enabled or disabled.
Voice-activated microphone: Supports 10 levels of sensitivity adjustment. Can be combined with the 5 conference modes. Sensitivity can be adjusted according to the on-site environment for optimal voice activation performance.
System version: Current version information of the host and microphones can be viewed.
Features 4 × 8-core interfaces providing 4 conference microphone input channels. Each channel supports 30 units and can be expanded with expander to connect more units.
Interfaces include: 1 × LINE RCA audio input, 1 × LINE RCA audio output, 1 × TEL telephone RCA audio input, 1 × TEL telephone RCA audio output, 1 × XLR balanced audio output, 1 × 6.35 mm unbalanced audio output, 1 × circular RS-232 interface, 1 × DB9 female RS-232 interface, 1 × DB9 male RS-232 interface, 1 × Phoenix terminal RS-232 interface, and 1 × Phoenix terminal RS-485 interface.
Can interface with central control systems, supporting control of individual microphone on/off, number of speakers, host volume, conference mode, and other functions.
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.
support dual-host backup by backup box.
Supports individual on/off control of each microphone via the software interface.
Supports customized AI noise reduction. Equipped with a new-generation intelligent noise reduction module and audio processing engine. Relies on deep learning algorithms for real-time noise reduction, echo suppression, and howling suppression. Filters environmental noises such as air conditioning, keyboard typing, fans, clapping, and page turning, while accurately recognizing human voices. Ensures clear audio pickup in complex scenarios and improves conference sound quality and communication effectiveness.
The main unit is equipped with 1-channel dry contact short-circuit input interface for fire linkage. It can be directly connected to fire alarm device, smoke detectors, temperature detectors, and other fire control systems to enable emergency linkage between the conference system and the fire system.
