Introduction - Ashly nX1504 Operating Manual

Operating Manual - nX, nXe, and nXp 150W/75W Power Amplifiers
 1 INTRODUCTION
Thank you for your purchase of this Ashly nX, nXe, or nXp multi-mode power amplifier. Each speaker output can be config-
ured for low impedance (2, 4, or 8 Ohm), or 25V, 70V, or 100V constant voltage output. This amplifier uses state of the art,
light weight, high power, high efficiency switching technology with active power-factor-correction, developed through years
of design and field testing. NX amplifiers are available in the following three series, designed to meet the most demanding live
sound and fixed installation sound systems in stadiums, arenas, performance venues, worship spaces and convention centers.
Series
nX - Base Series
nXe - Networkable
nXp - Network + DSP
 nX Base Series Standard Features
• Two or four channel lightweight design
• Universal input switch mode power supply with active power factor correction (PFC) that operates from 70VAC to 270VAC
• Individually configurable speaker outputs for low-impedance (2, 4, or 8 Ohm), or 25V, 70V, or 100V constant voltage
• Power-saving automatic sleep mode, less than 1W, defeatable
• Rear panel DIP switch per channel for selection of hipass filter, limiter, input gain, and speaker output mode
• Front panel power switch, defeatable
• Rear panel level controls, defeatable
• Front panel LEDs for temperature, current, signal, clip, mute, bridge mode, protect, sleep, and power switch disable
• Euroblock connectors on all inputs and outputs
• Remote DC level control per channel
• Detachable AC mains line-cord connector with automatic 120V/240V select
• Continuously variable cooling fan
• Amplifier protection: Shorted output power limiting, over-temperature, power supply fault, DC-output, mains fuses & inrush current limiting
• Five year warranty
 nXe Network Series Additional Features
• Ethernet control and monitoring of amplifier functions using Protea
• Ashly Remote app for iPad
• Serial data port for Ashly serial remote control devices such as the WR-5 or RD-8C
• Optional RS-232 data converter for third party controllers such as Crestron
• Software defeatable power switch and level controls
• Standby mode, 30% reduction from idle, triggered on or off by contact closure, software control, or event scheduler
• Programmable power-on delay for Off-to-On or Sleep-to-On transitions
• Preset recall via contact closure, software control, remote control, or event scheduler
• Aux preamp outputs
• Fault condition logic output per channel, fault indicated by loss of 1Hz "heartbeat" signal
• Optional factory installed Cobranet
 nXp Network + DSP Series Additional Features
• Protea DSP including dynamics, gain, EQ, feedback suppression, FIR filters, matrix and auto-mixer, crossover, delay, and more
• Impedance monitoring of individual amplifier outputs for quick and easy diagnosis of potential speaker problems
• iPad control of select DSP functions including gain, mute, matrix, A/B source select, PEQ filter level, and meters
• Networkable remote gain and zone control using Ashly neWR-5 and FR-8/16
