Ecler NXA4-400 Digital Audio Manager

Ecler NXA4-400 powered digital audio manager

The Ecler NXA4-400 is a self-powered digital audio manager, functioning as a hybrid of a digital matrix and a multichannel amplifier in a single all-in-one platform. It provides 4 analog audio inputs and 4 powered audio outputs, each channel rated at 400 W.

An integrated DSP processing module, configurable from EclerNet Manager software, provides comprehensive matrix functions with a dedicated audio input mixer per channel, allowing each output to generate an independent mix from the others rather than being tied to a fixed source routing.

Output channels can operate independently or paired, with two available modes: Bridge, where a pair behaves as a single higher-power amplifier, or Parallel, where a pair drives two separate loudspeaker loads from a shared signal. Remote management is available via Ethernet and RS-232, with TP-NET protocol support for third-party control system integration.

All NXA4-400 models feature convection cooling without a fan, keeping operation completely silent, a feature that makes them well suited to noise-sensitive environments such as libraries, lecture halls, and quiet retail spaces where a working fan noise floor would be unacceptable.
