Ashly NXP8004 Overview

The nXp Series NXP8004 4-Channel 800W Power Amplifier with Programmable Outputs & Protea Software Suite 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.

This amplifier features Protea DSP processing for efficient control. 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 included Protea Software Suite.

The amplifier offers 32-bit SHARC DSP processing (with 48 & 96 kHz sampling) for comprehensive audio processing and built-in signal generator for test tone and noise-masking. It also offers swept load impedance monitoring on each amplifier channel output.

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
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)
Use Protea software to remotely disable all front panel controls, including the on/ off switch, for a tamper-proof installation
