Усилитель трансляционный 2х375/250 Вт, 100V, 50V RCS AUDIO DBA-500 D

Усилитель цифровой 2x375/250W, 100V, 50V, 70-20.000 Hz, 2U. Произведено в Германии Description With this Digital 100 V Power Amplifier we do contribute to the protection of our climate and therefore the protection of our natural habitat. This device uses energy in a sensible manner and is part of an advanced technology development. The advantages of digital power amplifiers can be found regarding a much improved degree of efficiency of over 90% compared to other analogue amplifiers with approx. 70%. The out come of that the lost heat is way less, which is positive for the durability of the amplifiers and also for the complexity of the cooling of 19U racks. An additional cooling of the technics room is not necessary. Features Pilot tone inputs and malfunction message contacts for emergency power and the power amplifier predestine this amplifier for 100 V technology according to VDE 0828 / EN 60849. In case no signal is present, the amplifier automatically switches to standby and then only spends max. 9,9 W, if the signal is pending, e.g. in case of an emergency the amplifier will be ready for operation within 30 ms. These amplifiers are manufactured according to the latest assembly methods with high-quality components and are therefore perfectly suitable for professional continuous operation in 100 V alarming systems. The battery capacity for emergency power operation is notably less than with analogue amplifiers. Special protective circuits preventing engine idling, short circuit, over heating and an input delay are a matter of course. Output power and protection circuits according to IEC-268-5. Cooling takes place maintenance free without ventilation, which means that there will be no pollution and no follow-up costs. This device is therefore especially suitable for noise sensitive environments (offices, churches, conference rooms, etc.). Other distinctive features: low installation depth of only 260 mm
