Ashly NX1.54 Overview

The Ashly NX1.54 Programmable Output Power Amplifier features lightweight, energy efficient Class D switching amplifier technology combined with a switch mode power supply. The NX1.54 amplifier is designed to meet the needs of demanding live sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces, and convention centers.

The NX1.54 is a 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 2Ω) operation. When in Sleep Mode, the NX1.54 amplifier draws less than 1W.

2 and 4-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 (defeatable)
<1W sleep mode can be defeated for applications that are subject to third-party performance standards that prohibit a sleep mode.
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 120 or 240VAC operation
Extensive protection circuitry, continuously variable cooling fans
Multiple independent internal power supplies provide increased channel separation and reliability
