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.
