The nXp1.54 Network Power Amplifier from Ashly Audio is the networkable version of the nX amplifier. It comes with Ethernet control, serial data control, aux preamp outputs, instant standby mode, preset recall, fault condition logic outputs, and optional network audio and digital audio capability. All these are controlled using Ashly Audio's Protea software suite. This amplifier is designed to meet the most demanding live sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces, and convention centers.
The Network Power Amplifier adds 32-bit SHARC DSP processing (with 48 kHz and 96 kHz sampling) as standard equipment for comprehensive audio processing, with built-in signal generator for test tone, and noise-masking. Plus, you get precision load impedance monitoring on each amplifier channel output.
2-channel high-output, lightweight amplifier 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 <1W sleep mode is defeatable
<1W sleep mode can be defeated for applications that are subject to third-party performance standards that prohibit a sleep mode, including those used for Mass Notification and Emergency Communication Systems and those subject to ANSI/UL 2572.
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
Ethernet port for use with control and monitoring of amplifier functions, with front panel COM activity LED
Neutrik powerCON detachable AC mains connector
Switch mode power supply automatically detects 120 or 240 VAC operation
