With this digital 100V Amplifier we do contribute to the protection of our climate and therefore the protection of our natural habitat.


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 outcome 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.


Please consider the following 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/IEC 50849.
  • In case of no signal is present, the amplifier automatically switches to standby and then only spends 9.9 VA, 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, overheating 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.
  • Compliant with the standard EN 54-16.
