5Ecler NPA2500T/4000T makes use of a twin power supply and N-channel mosfets. This technology, whichhas been successfully implemented in the industrial product line ENVIRO, allows for very high output powerwithout the use of bridge configurations. The NPA2500T/4000T keeps its "All the Power All the Time" philosophy,even when driving 4 ohm speakers with a musical programme at maximum level.NPA series incorporates in addition important technological innovations concerning digital processing andremote management via Ethernet, turning it into the perfect candidate to address mobile applications and fixedinstallations, both centralized and distributed, requiring high level remote control and monitoring andintegration with standard Ethernet networks. NPA amplifiers include as standard an EclerNet internal modulefor DSP processing and remote management, allowing physical connection between the amplifier and an Ethernetnetwork and its management and remote supervision from any point of it, using Windows EclerNet Manager*software. Please refer to the EclerNet Manager software manual for more information.* EclerNet Manager software is available on www.ecler.com.3. INSTALLATION3.1. Location, assembly, ventilationThe NPA2500T/4000T amplifiers are 3 RU high 19'' rack modules.It is important that the amplifier, as a heat source, is not placed next to other equipment nor exposed to hightemperatures. Therefore, the ventilation path should be kept free to allow fresh air entering the forced ventilationtunnel. This system pulls air from the front, directly guiding it to the power modules and transformers, diverting apart towards capacitors and forcing its output through the rear panel of the amplifier.In order to optimize as much as possible the correct thermal dissipation of equipment installed in a closedrack, it is advisable not to place power amplifiers under other appliances, but upon these ones.All NPA amplifiers are supplied with plastic washers in order not to damage the rack ears when tighteningthe screws.3.2. Mains connectionThe NPA amplifiers are fed with alternate currents, depending on the country, of 110-120, 220-240V47/63Hz. (see characteristics in the back of the unit).WARNING!: By convention, the mains wire colour assignment is the following:- BROWN = Phase- BLUE = Neutral- YELLOW/GREEN = EarthThe mains cables must not be near the shielded cables carrying the audio signal, as this could causehumming.
