User manual DYNACORD PSX 1250

[. . . ] A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. [. . . ] CAUTION: Do not ship the power amp in any other but its original packaging. When shipping the power amp, make sure to always use its original box and packaging materials. Packing the power amplifier like it was packed by the manufacturer guarantees optimum protection from transport damage. 1 Warranty Certificate Keep the original invoice that states the purchase/delivery date together with the warranty certificate at a safe place. They are the premium choice as system drive for a variety of mobile and club sound systems. Their comprehensive protection system includes circuitry against overheating, overload, short circuit, HF and DC as well as backEMF and inrush current. loudspeakers are protected by turn-on-delay relays. The build-in patented LPN (Low-Pass-Notch) filter compensates for transient distortion in dynamic signals (such as kickdrums) to achieve a higher acoustic output and more punch. PSX 1250 power amps provide extremely high power output that might be dangerous for human beings as well as for the connected speaker systems. High output voltages can damage or even destroy the connected speaker systems, especially, when the PSX 1250 amplifier is operated in bridged mode. Prior to connecting any loudspeakers, make sure to check the speaker system's specifications for continuous and peak power handling capacities. Additionally securing the amplifier at the rear becomes necessary, if the rack case in which the power amplifier has been installed will be transported. Failure to do so may result in damage to the power amplifier as well as to the rack case. Attach the power amp as shown in the illustration using 4 case nuts and screws. Brackets for securing the power amplifier are available as accessories. As with all Dynacord power amps with fan cooling, the airflow direction is front-torear, obviously because there is more cold air outside of the rack case than inside. The power amplifier remains cooler and dissipating the developing waste heat in a specific direction gets easier. In general, setting up or mounting the power amplifier has to be done in a way that fresh air can enter unhindered at the front and exhausted air can exit at the rear. When installing the power amp in a case or rack system, attention should be paid to these details to provide sufficient ventilation. Allow for an air duct of at least 60 mm x 330 mm between the rear panel of the power amplifier and the inner wall of the cabinet/rack case. make sure that the duct reaches up to the cabinet's or the rack case's top ventilation louvers. Leave room of at least 100 mm above the cabinet/rack case for ventilation. [. . . ] DUAL In DUAL mode, the two channels of the power amplifier work independent from each other. This mode of operation is being used for all 2-channel applications, like stereo operation. Using the input level controls on the power amp's front panel allows independently adjusting the channels' amplification. Using the input level controls to independently control the amplification of the two channels is still possible because only the channels' inputs are linked. [. . . ]
