ENGLISH About ■ CobraNet is … An audio networking system developed by Peak Audio (a division of 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).
Two types of bundle can be used with CobraNet: “multicast” bundles and "unicast" bundles. Multicast bundles can be transmitted from a single device to all devices on the network, while unicast bundles are transferred from a single transmitting device to a single receiving device or a limited number of receiving devices. Unicast bundles are only sent to devices which have been set to the same bundle number as the transmitting device.
On any CobraNet network one device generates a timing signal that all other devices receive and are synchronized to. The device that generates the synchronization signal is known as the “conductor,” while all other devices are “performers.” The conductor for the network is automatically assigned and need not be specified by the operator. When an MY16-C is assigned to be the conductor for the network, the LED indicator to the right of the connector that is connected to the network will light orange.
ENGLISH The MY16-C System The internal signal flow of the MY16-C is shown in the illustration below. 16 audio inputs and 16 audio outputs are available, and for this example channels 1 ~ 8 are bundle 1, and channels 9 ~ 16 are bundle 2.

6 BUNDLE ASSIGNMENT [OUT1] and [OUT2] Rotary Switches These switches set the transmit bundle number for audio signals to be transmitted over the CobraNet network. The [OUT1] switches specify the transmit bundle 1 number, and the [OUT2] switches specify the transmit bundle 2 number. Two rotary switches are used to specify each number. See "Bundle Number Setting Procedure" on page 15 for details.

LATENCY n Set all CobraNet devices receiving and transmitting audio signals to the same latency. Clock Synchronization Mode (CLOCK 1/2) DIP switches 5 and 6 (CLOCK 1 and CLOCK 2) specify the clock synchronization mode to be used. See "Clock Synchronization Modes" on page 12 for more information.
ENGLISH Clock Synchronization Modes The MY16-C provides a selection of three clock synchronization modes: Network synchronization, host synchronization 1, and host synchronization 2. Network Synchronization In this mode the MY16-C receives synchronization from the network. This is the normal synchronization mode. When the MY16-C is set to network synchronization, make sure that the audio device in which the MY16-C is installed is synchronized to the MY16-C clock.

ENGLISH MY16-C Card Installation Procedure Carefully read the precautions on page 2 before installing the MY16-C. 1 Set the MY16-C circuit-board DIP switches and rotary switches as required for your application. Refer to "Circuit-board Switches" on page 9 for details about the switch settings. These switches cannot be accessed while the MY16-C card is installed in its host device.
