intensify the restrictions on Ethernet’s packet delivery times, and therefore reduce the max-

The number of channels assignable per single device:
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
).
Audio resolution:
This option is used to specify the audio resolution for bundle trans-
mission: 20 or 24 bit. Be sure to select 24-bit if you are using 24-bit digital audio. Otherwise,
your audio will be truncated to 20-bit.
Note: If the latency is 1.33 ms, the number of bundles that can be handled by this single device
on a CobraNet network will be limited to a total of four bundles for transmission and reception.
When changing the latency to 1.33 ms from some other setting, you will be unable to make
this change if the total number of bundles for transmission and reception is five or more.

Note: You can change the latency setting only while offline. In order to apply the setting to the
NHB32-C or ACU16-C, you must execute “Connect & send to network.” It is possible that
noise will occur somewhere in the system when you change the latency. To prevent damage to
speakers or other components, you should turn down the audio to the CobraNet network or
turn down the output of the power amps before making this change.
Note: If two or more latencies exist within a CobraNet network, there is a danger that the
devices may become unable to communicate correctly with each other. You must make the
same latency setting for all devices in a single network.
Note: If you are unable to change the latency, refer to Troubleshooting (see
Note: Two or more devices cannot transmit data in the same bundle. So do not assign the same
bundle to more than one group.
