User manual DYNACORD DRP 10

[. . . ] 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. I the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. [. . . ] Packing the power amplifier like it was packed by the manufacturer guarantees optimum protection from transport damage. 1 Warranty certificate including safety instructions 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 LPN (Low-Pass-Notch) filter compensates for transient distortion in dynamic signals (such as kick-drums) to achieve a higher acoustic output and more punch. SL 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 SL 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. Even if amplification has been reduced through lowering the input level controls on the amplifier's front panel, it is still possible to achieve full power output with a sufficiently high input signal. SL amplifiers are capable of producing dangerously high voltage output that is present at the output connectors. 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. Since temperatures inside of the cabinet/rack case can easily rise up to 40 °C during operation of the power amp, it is mandatory to bear in mind the maximum allowable ambient temperature for all other appliances installed in the same cabinet/rack case. CAUTION: Blocking/closing the power amp's ventilation louvers is not permissible. [. . . ] 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. PARALLEL operation is the mode of choice, whenever the same input signal drives multiple power amp channels of a large system installation. Typical Speaker System Cabling The first possibility in DUAL or PARALLEL mode is to use the two Speakon-type connectors, whereas speakers have to be connected to pins 1+ and 1­ of the sockets.
