NEXO is an AES67 network audio converter that sends and receives 2 channels of audio over Layer 3 IP networks. It’s part of LDA’s family of accessories for EN 54 voice evacuation and public address systems.
It acts as an ACSI v2 bus controller, connecting up to 32 MPS-8Z, MPS-8Z+, VAP-1 and VAP1-FES devices to the NEO+ system over IP networks. Ethernet communication runs on LDA’s ACSI Net protocol, which extends ACSI v2 devices up to 4096 units, including microphones and emergency panels, while keeping EN 54 certification across the network.
It includes an audio input/output port for music sources, plus configurable control contacts that trigger events on NEO+. NEXO manages single-site and multi-site architectures, the latter through the NEXO Hub card. For NEO+ networks that need redundancy, it has a dual Ethernet port with ring IP connection.
The NEXOS02 model comes with the NEXO Hub Lite licence included as standard, allowing ONE or NEO units to connect to the multi-site architecture over the ACSI v1 bus.
With a compact, versatile design, NEXO fits both rack and desktop installations.
