THE NEW AUDIO BET !

MP3/MP2 audio stream decoder board over IP

NS1 data sheet

Product overview

NS1 is designed for reliably reproducing and distributing MP2 and MP3 audio over Ethernet using IP protocols.

NS1 is the professional solution for applications requiring audio to be sent cost-effectively and easily over standard IP-Networks covering long distances and/or to multiple locations.

NS1 supports compressed audio in MPEG1 Layer II (MP2) and Layer III (MP 3) formats.

NS1 is ideal for audio transmission, live sound and streaming in standard IP/Ethernet networks.

NS1 applications can be user designed to control all units and linked to external equipment with the factory supplied OEM library (DLL). Fully programmable routing control permits sending audio to any NS1 or multiple groups of NS1's.
