AoIP Digital Audio Router_ACM3 Broadcast Control System

AoIP Digital Audio Router

CR100 is a multi format digital audio routing converter that can allocate input signals to output ports. Through internal routing bridging, connect the audio signals of traditional interfaces to the AoIP network, and integrate audio devices that do not support AoIP into the ACM3 system. Support AES70 based management functions, all monitoring management and routing configuration can be completed by the system, and can work together with other devices. Convert the media clock transmitted via PTP in the AoIP network into a word clock and output it to other digital audio devices to complete the synchronization signal transmission. The MADI interface can be used for batch collection of audio data from large devices, as well as for heterogeneous backup transmission of AoIP.
·Replaceable AoIP module
Support custom selection of different AoIP modules to achieve AoIP functionality provided by other vendors
·High impedance acquisition and loop out
AES/EBU and analog inputs both support high impedance bypass acquisition and provide input loop output interfaces
Can be installed in the transmission link to obtain the transmitted digital or analog audio
·Local configuration and remote monitoring
The routing relationship can be manually set by the panel or managed through the network. The routing table is protected against power outages and overloaded upon startup
Equipped with OLED display screen, supporting the display of level meter and local working status, capable of local monitoring of all source and target signals
·Power outage direct function
Support 1-channel AES3 and 1-channel analog audio power-off bypass direct connection
The first digital input and the first digital output are powered off and connected directly, while the second analog input and the first analog output are powered off and connected directly
·Collect device information through additional interfaces
3 auxiliary network ports: 8GPI+8GPO, RS232, RS485, used to connect other devices to collect information and send it to the management platform in AES70 format, achieving remote monitoring and surveillance functions
·Free selection of input type
Four input signals can be freely selected as analog or digital through the device dip switch
