Ashly NX752 overview

  • 1Description

The nX Series 2-Channel Multi-Mode Power Amplifier from Ashly is capable of driving 2, 4, and 8 ohms loads at full power and offers a maximum rated output power of 150W per channel at 25V, 70V, and 100V modes. It features a universal switch-mode power supply with PFC (Power Factor Correction) that operates from 70 to 270 VAC. The multi-mode output capability allows each individual amplifier output channel to be set for low-impedance (2, 4, and 8 Ohms) or constant voltage (25, 70, or 100V) operation using DIP switches.

The amplifier has power-saving Ashly EMS (Energy Management System) that provides an automatic sleep-mode drawing less than 1W. It is suitable for live sound and fixed installation sound systems in stadiums, arenas, performance venues, places of worship, and convention centers.

Selectable 80 Hz second-order Hi-pass filter, limiter, and input gain per channel
Remote DC level control per channel
Extensive protection circuitry, continuously variable cooling fan
Euroblock input and loudspeaker connectors
Detachable AC mains line-cord connector
