  • Product Name: MDA Series Card Type Programmable Central Controller with Audio

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) Innovative card plug-in type with 3 extension slots. Each slot can be inserted into MIC card to extend the MIC input. Meanwhile, can also insert into all kinds of extension card upgrade to small and medium-size central control system.

5) MDA series integrated our engineering application experience, specially designed for the medium-size intelligent conference room. It creatively integrates the function of 4 channel MIC input( can extend to 16 channel via extension card, include phantom power supply), pre-mixing processing, 4 channel stereo line input and switch, MIC INSERT, AUX IN/OUT, digital power amplifier, digital volume control module, power management module and central control system into one device. Its function is powerful and convenient to use.

6) Its MIC INSERT/RETURN interface designed for access feedback suppressor, improve the microphone pick up distance and avoid the microphone howling effectively. Unique in AUX IN/OUT interface used for audio OUT/IN in distance video conference system, it also have echo cancellation technology, can eliminate the inherent echo from distance video conference system.

7) Adopts CAN bus, creative card plug-in design, powerful expansion. Customer can equip with various kinds of extension card depends on their requirements, it avoid wasting and convenient to upgrade again.

8) There is 1 channel manageable power output, can supply power to peripheral device directly or by outlet.
