Ashly nX Series NX4004 4-Channel 400W Power Amplifier with Programmable Outputs

Description

The nX Series NX4004 4-Channel 400W Power Amplifier with Programmable Outputs 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.

4-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
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
