NX Multi-Mode Power Amplifiers are designed to meet the most demanding live sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces and convention centers.
Network Multi-Mode Power Amplifier, Ethernet, 4 x 75 Watts @ 2 Ohms
Available in three amplifier series, NX offers 2 or 4-channel models as NX (base model series), NXE (networkable), or NXP (networkable + DSP).
All NXE Models Include:
Class-D Switching Amplifier Technology.
NXE features a universal switch-mode power supply with Power Factor Correction (PFC) that operates from 70VAC to 270VAC.
Selectable Outputs allow you to choose the desired output mode on each channel. Set the DIP-switch configuration for Low Impedance
(2, 4, and 8 Ohm), or 25V, 70V, or 100V Constant Voltage and you're set to go.
NXP has power-saving Ashly EMS (Energy Management System) which provides an automatic sleep-mode drawing less than 1 Watt (defeatable).
Ethernet Control using Protea NE software.
Also, serial data control by Ashly programmable remotes or third party controllers, aux preamp outputs, instant standby mode, preset recall, fault condition logic outputs, optional Dante, CobraNet, or AES3 digital audio capability (factory-installed).
Real-Time Clock with Event Scheduler.
Assign automa c execu on of selected functions and tasks. The event scheduler is programmed from software and stored in the amplifier.
Ashly Remote Control via iPad app.
Use our free Ashly Remote app available for custom design of secure wireless control over network.
