internally. You can see this by the duplication of audio presence on the front panel meters. To
prevent confusion from duplicated audio signals in the system, the secondary CAB 4n is
prevented from transmitting onto the CobraNet network by the action of the Buddy Link.
Therefore, only one set of audio inputs is present within the system at a time in addition and for
the outputs the secondary unit’s audio output is muted. This prevents an audio “collision” of
duplicate audio output signals at the amplifiers.
The Buddy Link feature also monitors the integrity of the LINK CABLE. When using dual
CABs, a cable failure will cause the secondary unit to take over transmission onto the CobraNet
network. The Buddy Link functionality can also be placed under software control and is used in
systems where remote access to the link is required. (See the resource list at the end of this
manual for additional information on this topic.)
NOTE: Using the Link Connectors for creating redundancy is limited to “dual” CAB units.
Where additional CABs are used, additional redundant units must also be added.
