  • Product Name: MDA Series Programmable Multimedia Central Controller-6C
  • Model No.: MDA-6C

1) Patent product, obtained national compulsory CCC certification.

2) Both of software StrAV&MDA and StrIDE are obtained certification of copyright.

3) Support control by iPad, Android, RF Touch panel, PC and web server.

4) MDA series integrate our engineering application experience, specially designed for small and medium size intelligent conference room. It creatively integrates the function of 4 channel microphone inputs (include phantom power), pre-mixing processing, 3 channel stereo line input and switch, MIC insert, AUX IN/OUT, digital power amplifier, digital volume control module, power management module and centralized control on the 1U cabinet. Its function is powerful and convenient to use.

5) Its MIC INSERT interface can access feedback suppressor to avoid MIC howling. Its specific AUX in/out interface is designed to access audio IN/OUT of remote video conference terminal. MDA series has acoustic echo cancelers, can eliminate the inherent echo of remote video conference system.

6) There are kinds of digital port, (such as SR-NET, RS232, LAN, and RELAY, interface depends on specific models), It can be controlled by wired control panel, wired touch screen, RF wireless touch screen, Android pad and iPad. And it can control various digital devices by programming, The model with LAN interface, can upgrade to network central control so that one person can manage several conference room at the same time.

7) There is 1 channel manageable power output, MDA series can supply power to peripheral device directly or by outlet. It also can access professional digital power management equipment via its RELAY or SR-NET port.
