Full Digital DSP Conference System Microphone Processor for Array Mic

Product Description

Features

-The unique AUDIO-LINK digital ring network technology achieve full-digital signal transmission and processing.

-Single CAT5e cable transmits 64 channels of audio and various information.

-All microphone units support audio, ID independent output. Working with voice recognition system to achieve voice role separation.

-High-fidelity sound quality, lossless audio transmission technology, 48K audio sampling frequency, 20Hz ~ 20KHz response frequency.

-A single conference controller can realize the independent control and merging of 4 conference rooms, can handle the cascade of multiple conference controllers to realize the merging and separation of larger conference rooms (including conference management, etc.).

-"Hand-in-Hand-Loop-Network" connection makes the system always working perfectly no matter changing discussion unit or having any malfunctioned units.

-The sensitivity of the unit microphone and 8 segment equalizer EQ adjusted independently.

-The main controller comes with self-learning AFC automatic feedback algorithm, combined with array microphones, short-stem microphones to achieve ultra-long pickup distance.

-Support AGC (Automatic Gain Control)/AFC (Adaptive Feedback Cancellation)/ANC (Acoustics Noise Cancellation) Sound output by separated zones function, each zone is automatically adjusted according to the volume of the position of the microphone, achieve longer distances pickup without whistle.

-Echo cancellation, remote two-way real-time call with another conference controller or another third-party video conferencing terminal.

-USB recording, controller monitor, advanced noise cancellation technology to realize clearer recording.

-Display with date, time management, and support speech time, countdown speech.

-Optional DANTE output module with other DANTE equipment used.

-Can drive 2*120W POE speaker through extension main unit, support up to 16 POE speakers.

Functions

  

-Compliance with IEC 60914, GBT 15381-94.

-Connect with VIS-EXM extension main unit, it can expand to 5200 discussion units.

-"Hand-in-Hand-Loop-Network" connection and the system assigned to each unit independently ID to avoid ID conflict.

-Both wired/wireless discussion units can connect to the controller, fast and easily to adding delegate of meetings.

-Supports up to 8 wireless microphones to be turned on at the same time, adaptive avoiding interference technology to achieve stronger anti-interference ability, compliance with IEEE 802.11n standard Wi-Fi both for 2.4GHz and 5GHz.

-channel audio input, XLR or RCA type, for local audio input or remote video-conferencing input.

-Maximum 8-channel audio output, XLR, RCA or Phoenix type, can be connected to simultaneous interpretation output or partitioned output.

-Add the audio input box, the system can be connected to other condenser microphones or dynamic microphones, more choices for users.

-Built-in multi-way internal communication function.

-TCP/IP connection between controller and PC

-RS232 central control, realize microphone switch, priority, volume and other controls.

-RS232 or RS485 to send the PELCO/VISCA protocol to realize camera auto-tracking function.

-Hot plug-and-play, and auto-recovery function.

-Wide range of voltage from 100V~240VAC
-Without using PC software, our conference controller still owns following settings:

1. Limit on the number of speaking persons: By Setting the number of active units at the same time (Number is 1/2/4/6/ units), supports up to open 32 wired microphones in full-on mode.
2. Discussion modes:

"OPEN" Free for all, limited by the active units setting by controller, "VOICE" Can activate MIC by detecting sound without press button, "OVERRIDE" First in First out, "APPLY" To apply then to speak, "PTT" Press to speak (Optional), "ALL" Full open mode (Optional).

1. Voting function: Approve/Abstain/Object
2. Chairman unit has priority to close all other units or mute them temporarily
3. ,Chairman unit can approval the application for speaking from delegate
4. Simultaneous language interpretation

-With PC software to add more ways of voting:
      1. Approve/Object
      2. Approve/Abstain/Object
      3. Level: 1/2/3/4/5
      4. Ranking: --/-/0/+/++
-By using RFID card to identify, can realize voting with names.
