The Ashly’s nXp1.54 Network Power Amplifier with Protea DSP, its features lightweight, energy efficient Class D switching amplifier technology combined w/ multiple independent power supplies that provide increased performance, reliability.

Description

The nXp1.54 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.

nXp Series amplifier add 32-bit SHARC DSP processing (with 48kHz & 96kHz sampling) as standard equipment for comprehensive audio processing, with built-in signal generator for test tone, and noise-masking. Plus precision load impedance monitoring on each amplifier channel output. The nXp Series has all the features plus comprehensive signal processing using Protea™ DSP, as well as swept load impedance monitoring for system maintenance.

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
  • Ethernet port for use with 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 (INA-1)
  • Use Protea Software to remotely disable all front panel controls, including the on/off switch, for a tamper-proof installation
  • Real Time Clock with Event Scheduler
