Description
The nXe Series NXE4002 2-Channel 400W Power Amplifier with Programmable Outputs & Ethernet Control from Ashly is a Class-D switching amplifier combined with a switch mode power supply. This amplifier meets the requirements of demanding live sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces, and convention centers.
The rear panel has DIP switches for programming each channel output for either High-Z or Low-Z operation. This amplifier can be connected to a network with Ethernet control and features serial data control, aux preamp outputs, instant standby mode, preset recall, fault condition logic outputs, and optional network audio and digital audio capability, all controlled using the Protea Software Suite (not included).
2-Channel high-output amplifier with programmable output on each channel (High-Z or Low-Z, selected via rear panel DIP switches)
Power-saving, Energy Management System with automatic <1W sleep-mode (defeatable)
Front panel power switch and level controls (can be disabled for security)
Rear panel DIP switches per channel for selection of high pass filter, limiter, input gain, and High-Z or Low-Z speaker output configuration
Remote DC level control on each input channel
Switch mode power supply automatically detects 120 or 240VAC operation
Extensive protection circuitry and continuously variable cooling fans
Multiple independent internal power supplies provide increased channel separation and reliability
Ethernet port for control and monitoring of amplifier functions, with front panel COM activity LED
Serial data port for use with Ashly remote control devices, or optional RS-232 converter for third party controllers (not included)
Protea software allows to remotely disable all front panel controls, including the on/ off switch, for a tamper-proof installation
Real-time clock with event scheduler
Instant standby mode that can be triggered by contact closure, software control, or event scheduler for reduced power consumption
Programmable power-on delay
Preset recall via contact closure, software control, remote control, or event scheduler
Aux preamp outputs, and fault condition logic outputs
Optional Cobranet or Dante network audio and AES3 digital audio input with pass-through
Neutrik Combo XLR – 1/4″ TRS jack plus Euroblock input connectors
Neutrik speakON twist locking loudspeaker connectors for security, safety, and reliability
Neutrik powerCON detachable AC mains connector
Made in USA
