New Adelphi does not use traditional copper tie lines, but relies instead on Dante for audio traffic between facility spaces. It is particularly used in the recording studios and theatre, the latter of which uses Dante for all audio connections between mixing consoles, amplifiers and paging systems. The recording studios usually only require the use of Dante when routing audio from one studio to another, though it is used with the [[RedNet Portable Rack]] and as a primary output in [[Surround Mix]]. Because the audio is carried using standard IP network packets, transmission can be over twisted pair or optic fibre.

A number of protocols have been adopted for use in New Adelphi.
There is also further information available on the Cables and Connectors used for the building infrastructure.
Audio
Dante
Audinate's Dante (Digital Audio Network Through Ethernet) protocol delivers uncompressed, multi-channel audio over standard Ethernet with low latency using Layer 3 IP packets.
New Adelphi does not use traditional copper tie lines, but relies instead on Dante for audio traffic between facility spaces. It is particularly used in the recording studios and theatre, the latter of which uses Dante for all audio connections between mixing consoles, amplifiers and paging systems. The recording studios usually only require the use of Dante when routing audio from one studio to another, though it is used with the RedNet Portable Rack and as a primary output in Surround Mix. Because the audio is carried using standard IP network packets, transmission can be over twisted pair or optic fibre. This has the potential to connect any space in the University back to any New Adelphi facility serviced by PanelNet.
There are many Dante compatible devices available and any macOS or Windows computer can run the Dante Virtual Soundcard software.
Ultranet
Transmission of audio for headphone mixers in the recording studios is carried using Behringer's proprietary Ultranet protocol. Although this is based upon the AES3 standard, it is not compatible with AES3 devices due to its use of a combined twin-AES3 method of transmission, providing 16 channels of audio to any P16-M mixer, and the use of the 8P8C connector, which is not standard for AES3. The use of this connector does not allow Ultranet to communicate with Dante or any other IP based device.
Further details on the technical aspects of Ultranet can be found in this post on Reverse Engineering Stack Exchange. Example code for reading Ultranet traffic is provided on GitHub.
