LDA audioTech NEO 4250E - This is an extension controller and a 4 x 250 W amplifier or a 2 x 500 W amplifier for the compact EN 54-16 PA/VA NEO system.
This extension unit can scale the NEO system with an additional 4 zones, as it includes 4 channels of class D power amplifier for 100V or 70V lines.
Audio is transmitted from the main unit to this extension unit via a daisy-chain connection through 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 the unit remotely as part of the entire NEO system and to create events to perform actions in the system triggered by input level conditions, date and time, UDP command, a GPIO, or a button from the MPS microphone.
- 4 class D amplifiers of 250 W or 2 amplifiers of 500 W for 100V/70V lines
- 4 preamplifier outputs for connecting external PA amplifiers
- DSP: 7-band parametric input/output equalizer, intensity, LDA sound amplifier, independent volume control for each output channel, and audio filters
- Triple Ethernet port: for Digital Audio Cobranet, remote control and monitoring, and for system scaling with NEO-Extensions in daisy-chain mode using Flexnet technology (up to 1024 zones)
- Control for up to 16 LDA AT6 attenuators
- 6 monitored contact relays for integration with the Fire Alarm Control Panel
