Audio and video management all-in-one machine-Geffen Maxtrix Control System Manufactory CN

Audio and video management all-in-one machine

Audio and video management all-in-one machine, used for conference system, sound reinforcement system, lighting system, video switching, background management and so on centralized control of conference room system. Equipped with large memory to quickly process complex logic instructions, powerful built-in programmable interface, NCC can control almost all external devices (including third-party devices), and the unique BP BUS bus system can be expanded up to 256 network devices. THE BUILT-IN NETWORK CARD THAT SUPPORTS MULTIPLE CONNECTIONS IS CONVENIENT FOR MULTIPLE IPADS, IPHONES AND OTHER DEVICES TO CONNECT TO THE HOST. TCP/IP and UDP codes can be sent. Centralized management of meeting rooms is supported.

Built-in 8 input and 8 output audio processor, DSP processing capacity:400Mhz,400MIPS,2200 MFLOP.

Sampling frequency/quantization: 48kHz, 24Bit ADC, 24Bit DAC.

It can meet the needs of most conference rooms for audio processing.

Applications: conference rooms, command and control centers, large multimedia conference halls.

4 IR emitting ports, each independent of each other (only one IR port is valid at any time).

8 two-way programmable RS-232 communication interfaces;(one of which is built into the machine to control the audio processor).

1 RS232 auxiliary program transmission interface.

2 bus interfaces for connecting peripheral devices.

Download the user program through the network.

ONE ETHERNET INTERFACE (SUPPORT TCPIP PROTOCOL) FOR CONNECTING IPAD AND OTHER WIFI DEVICES, WHICH CAN SUPPORT UP TO 16 IPAD AND OTHER WIFI TOUCH SCREENS TO CONNECT TO THE HOST AT THE SAME TIME.

Support sending TCP/IP and UDP codes.

Built-in matrix control module that can program a matrix control program in 5 minutes.

Support centralized management of meeting rooms: Centralized query of the working status of multiple conference rooms, and one-click shutdown of conference room equipment.

The user establishes its own infrared code database, which can realize infrared logic control such as one-click dual code. Larger capacity IR storage space.

The timing lock function can be set.

Provide open programmable control platform, user-friendly Chinese operation interface and interactive control structure.

SUPPORT ANDROID, IPAD/IPHONE, WIRED TOUCH SCREEN, WALL SWITCH AND OTHER CONTROL INTERFACES.
