CobraNet is …
An audio networking system developed by Cirrus Logic, Inc. that allows real-time transmission and 
reception of uncompressed digital audio signals via a Fast Ethernet network cable. The network 
can simultaneously handle up to 64 input and output channels, for a total of 128 channels (64 
channels if repeater hubs are used). The maximum number of channels than can be handled in 
practical situations may be lower due to performance limitations imposed by the equipment used 
and the condition of the audio signal.
Currently, the CobraNet network will handle 16, 20, or 24-bit audio at sampling rates of 48 or 96 kHz.
The CobraNet network is capable of transmitting control data at the same time as the audio 
signals. The types of control data transmitted are determined by the equipment used.
The CobraNet network imposes a 5.33-millisecond (2.67 milliseconds or 1.33 milliseconds with 
some settings) latency on transferred audio signals. Latency and bit depth can be set via the 
CobraNet Manager application.

Bundles
Audio is transmitted over the CobraNet network in units known as “bundles.” These bundles are 
processed at the receiving end to reconstitute the original audio signals. In the case of the 
MY16-CII a bundle can contain up to eight channels. Each bundle is identified by a number from 1 
to 65,279, and audio transmission via the network becomes possible when the same bundle 
number is specified at both the transmitting and receiving devices. Bundles can be transmitted and 
received over the entire network as long as sufficient network resources are available. The actual 
number of bundles that can be handled will depend on the capabilities of the equipment used.
The MY16-CII can use up to 4 output bundles and up to 8 input bundles. Bundle numbers can be 
assigned via the CobraNet Manager application.
