The STR NLK03 NPU Network Learning Kit (Audio Insert) is the highest range of the first generation development kit from Stream-Plus. The kit allows developers to encode analogue audio into live network stream. Apart from that the kit also shares all the functionalities of the STR NLK02, allowing it to also receive and decode IP audio streams back into analogue audio.  The kit supports a large number of protocols, when coupled with multiple STR NLK02 along with the provided UCX software framework, developers can easily create a network paging system with multiple zone control or even a distributed network background music system with live audio streaming.
