Description

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.

LDA NEO Extension 4500 is an extension controller

and a 4x500W amplifier or 2x1000W amplifier for the

compact EN 54-16 PA/VA system NEO.

LDA NEO Extension 8250 is an extension unit for the EN

54-16 PA/VA system NEO.

The extension units can scale the NEO system with four/ eight more zones as it includes four/ eight class D power amplifier channels at 100V or 70V lines. Audio is transmitted from the main unit to this extension unit via daisy-chain connection via FlexNet.

Therefore it guarantees maximum quality and integrity.

The extensions are 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 button from MPS microphone.

Features and benefits:

Four/ eight class D amplifiers for 100/ 70V lines.
Four/ eight pre-amp outputs for external PA amplifiers connection.
DSP: 7-band input/output Parametric Equalizer, loudness, LDA sound enhancer, independent volume control per each output channel and audio filters.
Triple Ethernet port: for Digital Audio Cobranet, remote control and supervision, and for escalating the system with NEO-Extensions in daisy-chain mode with Flexnet technology (up to 1024 zones).
Control for up to 16/ 32 attenuators LDA AT6.
Six/ twelve supervised contact relays for integration with Fire Alarm Control Panel.
