LDA audioTech NEO 8250 ES03 – 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 8 additional zones, including 8 channels of 250W Class D amplification.
The audio signal is transmitted from the main unit to this extension unit via a daisy-chain connection by Flexnet and using audio over Ethernet. Therefore, it guarantees maximum audio quality and signal integrity.
The NEO extension is fully configurable with the NEO-Configurator software (included). It is possible to configure the unit remotely as part of the entire NEO system and to create events to perform actions in the system, triggered by conditions of: input level, date and time, UDP command, a GPIO, or a button from the MPS microphone.
- Extension unit of the LDA NEO+ system certified in accordance with EN 54-16.
- Allows the NEO+ system to expand by up to 8 additional zones, as it includes 8 channels of 250W.
- Class D amplification @ 100V per channel.
