LDA audioTech NEXO S02 - is an AES67 network audio converter that allows the sending and receiving of 2 audio channels over IP networks at layer 3. This device is integrated into the LDA EN54 family of accessories for voice alarm systems and sound reinforcement systems.
It features 2 bidirectional ACSI ports, one of which has redundant capability, allowing the connection of up to 32 additional devices per unit via the ACSI v2 protocol, compatible with any LDA system, such as NEO+.
Ethernet communication is achieved through the LDA ACSI Net protocol. This enables NEXO to extend ACSI v2 devices up to 4096 units, such as microphones and emergency panels, by interconnecting them while maintaining EN 54 certification. With a compact and versatile design, NEXO is perfectly suited for rack or desktop installations.
