The NXE1.52 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.

2-channel high-output, lightweight amplifier with programmable output on each channel

Note:

Hi-Z or Lo-Z, selected via rear panel DIP switches
Power saving, Energy Management System (Ashly EMS) automatic <1W sleep mode is defeatable Note: <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 Note: 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 Ethernet port for use with control and monitoring of amplifier functions, with front panel COM activity LED Serial data port for use with Ashly remote control devices, or RS-232 converter (sold separately) for third party controllers (INA-1) Uses Protea software to remotely disable all front panel controls, including the on/off switch, for a tamper-proof installation Real-time clock with event scheduler Instant standby mode, 30% reduction in power consumption with on/off triggered by contact closure, software control, or event scheduler Programmable power-on delay Preset recall via contact closure, software control, remote control, or event scheduler Auxiliary preamplifier outputs and fault condition logic outputs Cobranet or Dante network audio (sold separately) and AES3 digital audio input with pass-through Ducking at mixer, peak hold indicator, in/out per filter, key engage, lock per filter, and global lock Ashly NXE1.52 Specs General Specifications Maximum Output Power Max Output Power Per Channel, EIAJ Test Standard 2 Ω: 1,500 W, 4 Ω: 1,500 W , 8
