The Ashly nX1.54 Power Amplifier designed to meet the most demanding live sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces and convention centers.

Description

The nX1.54 Power Amplifier designed to meet the most demanding live sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces and convention centers.

Sound systems in large architectural spaces require flexibility and big power whether it’s for line arrays, distributed sound systems, Left/Center/Right 3 and 4-way speaker systems, our new nX Series delivers up to 12,000W of clean power in a convenient 2U package. What’s more impressive is the nX Energy Management System with defeatable <1W sleep-mode (<1W energy consumption beats the most aggressive Energy Star benchmark†). nX Amplifiers have multiple independent power supplies that provide increased performance and reliability.

nX Series is the base level amplifier, available in either 2 or 4-channel models. Use rear panel DIP switches to program each channel output for either High-Z (70V or 100V Constant Voltage) or Low-Z (stable down to 2 Ohms) operation. When in Sleep Mode, the nX amplifiers draw less than 1 Watt.

Features

  • 4-channel high-output, lightweight amplifiers with programmable output on each channel (Hi-Z or Lo-Z, selected via rear panel DIP switches)
  • Power-saving, Energy Management System ‡ (Ashly EMS) automatic
  • Front panel power switch and level controls (can be disabled for security)
  • Front panel LEDs for temperature, current, signal, clip, mute, bridge mode, protect, sleep, and disable (of front panel controls)
  • Neutrik Combo XLR – 1/4" TRS jack plus Euroblock input connectors
  • Neutrik speakON twist locking loudspeaker connectors for security, safety, and reliability
  • 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
  • Neutrik powerCON detachable AC mains connector
  • Switch mode power supply automatically detects 120V or 240V AC operation
  • Extensive protection circuitry, continuously variable cooling fans
