AoIP option is installed. The iAM-AUDIO is set up at the Wohler factory to be used as a slave rather than a master within the Dante network. Other devices or software, such as a Dante Controller, are expected to be responsible for most device configurations and all audio routing.
What is in the iAM-AUDIO for Dante The Audinate® Brooklyn II board automatically recognizes Dante networks when installed, will alert other devices of its presence and configuration, and will configure its AoIP address per DHCP or local link protocols. There is no need to set a static address for the iAM-AUDIO Dante port, so no address entry method is provided in the iAM-AUDIO for Dante network setup.
Dante Device Setup iAM-AUDIO’s default Dante Device Name is “BKLYN-II- …” followed by the last 6 digits of the Dante port MAC address, as shown in Figure B-3. This name can be changed by the Dante Controller to appear that way on the network, but that will not change the iAM-AUDIO’s unit name appearing on GUI pages and iAM-AUDIO remote metering or discovery pages.
Other changes such as Latency settings can be made by the Dante Controller through the Device View menus. Some changes may require remote rebooting of the Brooklyn II card to take effect, temporarily interrupting audio and publishing the new information to the network. Only 44.1 kHz and 48 kHz audio sample rates are currently supported by the iAM-AUDIO.
page to match. AES67 The iAM-AUDIO Brooklyn II can be configured for AES67 operation. AES67 operation with Dante is limited to eight or less receive and transmit channels at 48 kHz sample rates. 24 bit linear (L24) encoding and 1 msec packet time are fixed default transmit parameters.
Figure B–7: Device View - Network Config The channels to be multicast are selected in the File menu-Create Multicast Flows window shown in Figure B-8. Figure B–8: Multicast Device Lock Audinate recently added a feature whereby a remote controller can send a command to lock Dante network devices’...
Dante Firmware Upgrades Wohler iAM-AUDIO monitors ship with current Brooklyn II firmware as of the option installation date. The version information is found in the Dante Controller Device View-Status page. iAM software/firmware is tested with the latest Dante code release. Therefore it is strongly recommended that iAM-AUDIO and Dante software/ firmware be updated at the same time to ensure compatibility and support of the latest features.
