41. IMPORTANT NOTECongratulations! You're the owner of a carefully designed and manufactured product. Thank you for yourconfidence and your choice of our NXA series multi-channel digital processing amplifier, with Ethernet and RS-232remote control.In order to obtain maximum operativity and perfect functioning order, it is most important to carefully readall considerations taken into account in this manual before connecting this amplifier.We recommend our authorised Technical Services if any maintenance task should be needed so thatoptimum operation shall be achieved.The NXA series is guaranteed for 3 years.1.1. PrecautionsThe equipment must be correctly grounded (ground resistance, Rg = 30 or less). The environmentmust be dry and dustless. Do not expose the unit to rain or water splashes, and do not place liquidcontainers or incandescent objects like candles on top of the unit. Do not obstruct the ventilation grilleswith any kind of material.If the device requires any intervention and/or connection/disconnection, it must be first powered off.Do not handle the speaker output terminals with your device turned on, there are voltages up to 400Vpp.The output cabling should be connected by a qualified technician. Otherwise only use pre-made flexible cables.There are no user serviceable parts inside the amplifier.2. INTRODUCTIONThe NXA series consists of two models with 4 channels and two models with 6 channels:o NXA4-80: 4 x 80 W RMS @ 4o NXA4-200: 4 x 200 W RMS @ 4o NZA6-80: 6 x 80 W RMS @ 4o NZA6-200: 6 x 200 W RMS @ 4All models are equipped with convection cooling, without fan, a feature allowing a very quiet operation,suitable for installation in noise sensitive environments.The output (amplified) channels can work independently or paired, two operating modes being thenavailable: BRIDGE (one pair behaves as a single higher power amplifier) or PARALLEL (one pair has two amplifiedoutputs, but both receive and deliver identical signals, simultaneously managed).It also incorporates significant technological innovations regarding digital processing and remotemanagement via Ethernet and RS-232, making it the perfect candidate to undertake mobile applications and fixedinstallations, centralized or distributed, requiring highly integrated remote control and monitoring withstandard Ethernet networks. NXA units are delivered with an internal DSP processing module and matrixfunctions, as well as EclerNet remote management, that allows the physical connection of the amplifier to anEthernet network and its remote management and monitoring from anywhere on this one, using EclerNet Manager(*) Windows® application. Please refer to the EclerNet Manager software manual for more information.Other remarkable features of this series are : 4/6 analogue audio inputs 4/6 amplified output channels (SINGLE (independent), PARALLEL or BRIDGED modes) 4/6 GPI remote control ports (compatible with 0-10VDC analogue devices, such as WPmVOL andWPmVOL-SR wall panels). A GPI port can control one or more inputs or outputs (volume) or managethe recall of presets 1 to 5 (GPI-1 only) Class D amplifiers (optimal energy consumption) Auto stand-by function (optimal energy consumption) 100% silent, thanks to unforced convection cooling (no fan) First class digital audio codecs, with excellent signal-to-noise ratio Ethernet interface, supporting EclerNet Manager software platform and UCP (User Control Panels)web server-web client remote control system RS-232 Interface
