For reliable network audio transport, Lectrosonics has developed the SPNDNT network processor to expand the ASPEN digital matrix processor family. The new network processor is a full featured DSP processor that can address both the ASPEN and Dante matrices and add mixing, gain and delay functions to the digital audio signals.
Any of the 48 final mixes in the ASPEN matrix can be assigned to any one or more of the Dante channels for transport to other endpoints in the network. Dante signals can also be imported into the ASPEN matrix in a local processor subsystem for mixing with other local and network signals, and then routed onward to other local or network devices.
Audinate is a leader in connecting networks by transporting high-quality media over standard IT networks. Its Dante products deliver a self-configuring, plug-and-play digital audio network that uses standard Internet Protocols. Dante offers a migration path to upgrade to new standards such as the IEEE Audio Video Bridging (“AVB”). The Dante network also provides auto discovery and master/slave configuration to synchronize the system clock.
The new processor debuted at the ISE2012 Convention in Amsterdam in January. A redundant network was installed in the exhibit stand between two ASPEN processor stacks, with audio transported back and forth for demonstration. Audinate reports that part of the demonstration involved disconnecting one of the network cable connections while listening to the audio signal to test the redundancy. The company states that "there were absolutely zero audible artifacts when the cables were disconnected and re-connected."
