While waiting on some responses from the Dante support team we decided to fire up the AVB devices we had acquired to test them out on an organ we have in production. This organ is to be in a church where the console will be in the back of the room and the speakers are about 200 feet away as the wire runs.
AVB stands for Audio Video Bridging and is an IEEE 802.1 technique to send high speed low latency digital audio over Ethernet cable (Cat5e or Cat6) and convert it to analog sound out of speakers at the end of the Ethernet cable. At this time the primary proponent of AVB seems to be MOTU with the primary computer being Apple computers using OSX 10.8 or later or a Windows 7 PC. For operation as an AVB Ethernet Audio Interface you need a Mac OS X 10.10 or later. The Cat5e cable length is 327 feet or there abouts.
Unlike Dante which is a simplistic hardware based system, the AVB system is very dependent on the MOTU software modules provided in the modules and on their website at http://www.motu.com/avb but once downloaded and configured the MOTU AVB ran flawlessly with the several organs tested.
Since we were using a PC, the first module in the console must be connected to the computer via USB or Thunderbolt. Those using the Apple Mac with OS X 10.10 can connect to the first module with Ethernet but since there is only one Ethernet connector it will be necessary to have an AVB switch to connect two or more modules. Since we had the PC we connected to the first module with USB and to the second with Cat5e. Had we wanted more modules in our network an AVB switch would have been necessary. We got all of the routing figured out pretty quickly and were able to get sound out of the console module but the one in the speaker room was not passing any audio. A quick call to the MOTU support department got us pointed at the master clock selection, which we had ignored, and once that was remedied it all responded as expected.
It appears that things like Antiphonal divisions and speakers for the choir can be handled by the addition of an AVB module and a length of Cat5e cable.
