4 NHB Pages
This chapter explains the NHB pages, which can be selected while an NHB32-C is selected
in the network tree.
Devices on a CobraNet network transmit and receive audio data by matching bundle num-
bers. Matching the bundle number on the transmitting and receiving devices is analogous
to making a physical cable connection between two devices. For example, if the Transmit
bundle assignment (CobraNet Output) on NHB32-C #1 is set to bundle #5, and the Receive
bundle assignment (CobraNet Input) on NHB32-C #2 is also set to bundle #5, audio data
in bundle #5 will be carried from NHB32-C #1 to NHB32-C #2.
CobraNet Page
This page is used to assign CobraNet bundles and to set the audio resolution of transmitted
bundles.
CobraNet distributes digital audio data in bundles. A single bundle can carry eight channels
of 20-bit/48 kHz digital audio, or seven channels of 24-bit/48 kHz digital audio. The
NHB32-C supports bundles 0 through 16,383 (multicast and unicast). Bundle 0 is not
really a bundle as such, more of a null setting used to disable transmission or reception.
Enable Unicast: When this option is unselected, multicast bundles 0 through 255 can be
specified. When it’s selected, bundles 0 through 16,383 can be specified. Bundles 256
through 16,383 are unicast bundles.
Receive bundle assignment: These parameters are used to specify the bundles that
contain the CobraNet channels you want to patch to the NHB32-C’s AES/EBU outputs. You
can patch the individual channels in each bundle on the NHB Patch page (see page 15).
Transmit bundle assignment: These parameters are used to specify the bundles that
contain the CobraNet channels you want to patch to the NHB32-C’s AES/EBU inputs. You
can patch the individual channels in each bundle on the NHB Patch page (see
page 15).
Note: Two or more devices cannot transmit data in the same bundle. So do not assign the same
bundle to more than one group.
