Specifications
Remote control; Adopt CobraNet Protocol ;DSP Processing;Network transmitting; Ethernet; Computer Operational; Integrator systemGeneral Speaking:
AudioNet is an integrated application platform with multi functions, such as matrix switching, audio transmission, comprehensive audio processing and remote control, able to satisfy all requirements of large sound systems. AudioNet is composed of various types of transmission modules (DRC series), audio processing modules (DRB series) and operation software (RS1200). Users can choose free according to system request.
SYSTEM FEATURES:
1 Audio signal transmit by means of real-time network, and long-distance control. Low cost of installation and maintenance.
2 It can save cable cost, and reduce installation workload.
3 Adopt CobraNet Protocol. All audio signals are digitalized and transmitted through Ethernet and avoid the distortion and other interference in analog signal transmission.
4 The signal transmission direction can be set by the professional software, and saved in the transmitter. After the system setting is finished, a firm templet can be created in the processor, and be operated independently without PC. It has a high flexibility and high quality-to-price-ratio.
5 Transmission can be from single point to single point, from single point to multi-point, or in radiation. It is easy to send audio signal in matrix transmission.
6 The audio processing is fulfilled by the operation of design, adjustment, and connection through software on PC. There are more than 100 processing modules. Convenient and reliable control.
DSP Functions of Processor Module:
Crossovers: 2 way,3 way ,4 way
Level Meters:1 way, 2 way, 4 way, 8 way
Features of Processor Module:
Easy installation
You can easily process the audio signals by connecting the DRB to the Cobranet audio system.
Easy operation
The DRB network DSP can be controlled by simple graphic operation software, 8 work modes can be pre-set for easy operation.
Flexible configuration
All DRB process parameters can be stored in flash memory
Redundant network connection
Different models can be optional, maximum has 2 analog audio input ports, 6 analog audio output ports and 2 CobraNet ports.
Powerful audio DSP functions, contains multiple virtual audio devices in RS1200 software. Lots of professional audio equipments can be replaced by these virtual audio devices in RS1200 software.

RS1200 software is a Digital Audio Platform, which provides distributed digital audio, signal processing, and control. RS1200 is a networkable, decentralized audio system, which is easy to configure & program. The program lets you create simple or complex audio signal processing solutions using a simple and intuitive drag-and-drop interface. Download the finished design to the C-MARK CobraNet device and you're up and running. This modularity extends past the individual processors because you can link multiple processors together and share audio between them.
