DBA-4500  D - DIGITALNI CLASS D OJAČEVALNIK  4 X 500W

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 19˝ 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 0833-4/VDE 0828/EN 60849.
• In case no signal is present, the amplifier automatically switches  to standby and then only spends 4 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.
• Output power and protection circuits according to
• IEC-268-5
• The LED indicators on the front panel give information on important signal and operation status.
• 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.).
• Special protective circuits preventing engine idling, short circuit, over heating and an input delay are a matter of course.
• Other distinctive features: low installation depth of only 260 mm and countersunk volume controls.
• The devices have loudspeaker outputs and symmetrical inputs on  screw-type connectors, whereby the wiring complexity is reduced  significantly.
• The inputs can be optionally equipped with input transformers. In this case please order as option the TSE-203.
