Audio over IP Transceiver Card

NMX-ATC-N4321-C Audio Transceiver Card

The NMX-ATC-N4321 Audio Transceiver is an audio-over-IP solution that both sends and receives two-channel balanced or unbalanced audio over IP. Simply connect a balanced audio input into the IN port and it's converted to IP packets that are switchable and routable just like data or voice. The balanced audio output receives an audio-over-IP stream and decodes to analog while preserving audio fidelity. Perfect for point-to-point or point-to-multi-point audio delivery, the NMX-ATC-N4321 provides audio matrix switching and distribution using the same control options as SVSI's Networked AV video switching and distribution solution.

With two auto-sensing gigabit Ethernet ports, units can be stacked to deliver low-latency multi-channel audio over a house network or a physically separate network. One Ethernet port is POE for use with a POE switch, eliminating the need for an external power supply. An audio matrix with any number of inputs and outputs can be constructed with the NMX-ATC-N4321. Since control is the same as for SVSI's video over IP matrix, video and audio matrices can be combined and routed using the same controller for the ultimate in digital media distribution.
