Bls-4513c/D Video-Tracking Function Conference System

BLS-4513C/D video-tracking function conference system

Function:
Controller: BLS-450M
*It is a discussing and video-tracking wired conference system.
*The front panel adopts buttons to control speaking mode and the number of speakers, breaking the traditional dial control.
*LCD screen displays working status.
*The number of speakers: 1, 2,3,4,5,6 and full opening.
*7 meeting work modes: 1.chairman mode 2.first in first out mode 3.Last in first out mode 4.LIMIT mode 5.FREE mode 6.responder mode 7.Apply speaking mode (just for BLS-4505C/D unit)
*The host can connect 60 microphone units, it divide into 4 parallel outputs, each channel can connect 20 units. It also able to connect expansion unit number of extended machine up to 5000 units by power extended machine BLS-350HD(under 255 units) or data extended machine BLS-350HS(above 255 units).
*Equipped with audio parallel output and a 6.3 jack output, conference recording outputs and background music inputs interface.
*Built-in telephone coupler input and output ports, and can be used for remote telephone conference. According to the principle of communication, it divide two-way telephone voice signals into inputs and outputs. In order to control the intercom setting of phone call and set aside between the hall.
*RS232 interface can be achieved using computer software to control entire conference system function.
*Designed with frequency shift feedback function,there is a key in the back pannel to control turn on and turn of the function.
