LDA audioTech NEO 4500 LES03 – This is an extension unit for the LDA NEO+ (S03) system, certified according to EN 54-16. This unit allows the expansion of the NEO+ system by up to 4 additional zones, including 4 differentiated Class D amplification channels, up to 500W (4Ω) per channel.
The included NEO Configurator software allows remote configuration of the equipment and the creation of events to perform actions in the system based on the state: input level, date and time, UDP command, GPIO, or from the MPS-8Z, MPS8Z+, and VAP series microphones.
