❏ “PRIMARY & SECONDARY CobraNet ports” (page 22)

Incorrect—Primary and secondary can be used to build redundancy into systems. Under normal conditions, the

ACU16-C uses the PRIMARY port. However, if communication via that port fails, it will automatically switch to the

SECONDARY port and operation will continue uninterrupted.

Correct—Primary and secondary can be used to build redundancy into systems. Under normal conditions, the ACU16-

C uses the PRIMARY port. However, if system problems such as port malfunction or broken cable occur in the PRIMARY

port, it will automatically switch to the SECONDARY port. The audio signal will be momentarily interrupted, but the

duration of the interruption will depend on the performance and settings of the hub, and on the structure of the system.

❏ “Introduction” (page 25)

Incorrect—Up to eight NHB32-Cs can be used on a single CobraNet network, providing bridging between 512

CobraNet audio channels and 512 AES/EBU format inputs and outputs.

Correct—Up to eight NHB32-Cs can be used on a single CobraNet network, providing bridging a maximum (total

inputs and outputs) of 256 channels of CobraNet audio and AES/EBU audio.

❏ “CobraNet Primary & Secondary” (page 35)

Incorrect—In the ﬁrst example, if a primary connection fails, the system automatically switches to secondary and

operation continues uninterrupted. However, if the switching hub fails, the entire system stops working. In the second

example, individual switching hubs are used for primary and secondary, so even if switching hub A fails, operation

continues on secondary via switching hub B.

Correct—In the ﬁrst example, if a primary connection fails, the system automatically switches to secondary. However if

the switching hub fails, the entire system stops working. In the second example, individual switching hubs are used for

primary and secondary, so even if switching hub A fails, operation continues on secondary via switching hub B.

Be aware that with either connection, the time required in order to switch between primary and secondary will depend on

the performance and settings of the hub.

❏ “CobraNet Primary & Secondary, Ex. 2” (page 35)

In consideration of a case in which the primary connection fails, connect switching hub A and switching hub B.
