Sennheiser ADN CU1, Bộ xử lý trung tâm, kết nối 40 máy đại biểu

The Sennheiser ADN CU1 Digital Central Conferencing Unit is part of Sennheiser's ADN conferencing system. Depending upon cable lengths, the device can connect up to 40 ADN microphone conferencing units via RJ45 cable. The system can be expanded even further up with to 400 microphone conferencing units by connecting 15 ADN PS power supplies into the system. The central unit can be set up as a standalone device on a flat surface or placed into a 19" rack using the optional rack ear adapters.

Once set up, the device can operate in Direct Access, Override, Push To Talk, or Request mode. In Direct Access and Override mode, any person can speak simply by pushing the microphone key button on their D1 delegate or C1 chairperson conferencing unit. In Direct Access mode, new speakers must wait for someone to stop speaking if the microphone limit for simultaneous speakers has been reached. Once someone stops speaking, the new speaker is automatically granted permission to speak. In Override mode, the new speaker can speak immediately and will override whoever has been speaking the longest.

In Push To Talk mode, new speakers will not be able to speak until the number of simultaneous speakers goes below the microphone limit, and permission will be granted to whoever pushes their microphone key button. In Request mode, a delegate presses the microphone button to join the list of people waiting to speak, and is granted permission to speak when the chairperson presses the next button on their conference unit. Depending upon the situation, you can adjust the Conference Mode, Microphone Limit, and Request To Speak limit to suit your requirements. You can also control the way time is managed, including the talk time limit for any speaker, the amount of warning before the talk time limit, and whether or not the speaker will be allowed to continue speaking or will be abruptly cut off if the talk time limit is exceeded.

Integrated PC with Control Software

The central unit includes an integrated PC that you can use to configure the devices settings. To do this, you connect a mouse, keyboard, and screen to the central conference unit and run the conference manager software. Alternatively you can install the Conference Manager software on a Windows PC and connect the PC to the central conferencing unit over a network. The software gives you advanced controls over delegate lists, speaker priority, equalization, and audio output levels

Foreign Language Menu

The central unit allows you to set the menu language in your choice of Chinese, Danish, Dutch, English, Finnish, French, German, Italian, Japanese, Russian, Spanish, or Swedish

Electronically Balanced XLR In and Out

For connecting music or other sound sources and for sending audio out of the central unit to speakers, the device includes electronically balanced XLR inputs and outputs

Malfunctioning and Error Monitoring

The unit will automatically detect and display an error message if the cabling to a conference unit is incorrectly connected

Feedback Suppression

The control software for the central unit includes feedback suppression filtering to prevent the conference unit speakers from feeding back into the microphones

Record Conference to USB Storage Device

You can record the conference by connecting a USB mass storage device to one of the two USB 2.0 plugs on the back of the unit. To record, it is recommended that you have a storage device with 1 partition and more than 500 GB of available space

Low-Noise Fan

So that the central conferencing unit may be in the same room as the conferencing microphones, the unit is equipped with a low noise cooling fan
