Description



The nX Series NX8004 4-Channel 800W 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.


 


Features:


 



  • 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
