LDA NEO Extension 4250 is an extension controller and a 4x250W amplifier or 2x500W amplifier for the compact EN 54-16 PA/VA system NEO. This extension unit can scale the NEO system with 4 more zones as it includes 4 class D power amplifier channels at 100V or 70V lines. Audio is transmitted from the main unit to this extension unit via a daisy-chain connection via FlexNet. Therefore it guarantees maximum quality and integrity. The extension is fully configurable with the NEO Configurator software (included with NEO). It is possible to configure remotely the unit as part of the whole NEO system and create events to perform actions in the system triggered by conditions of input level, date&time, UDP command, a GPIO or a button from the MPS microphone.
