Compact amplifier 100W

Compact amplifier 25 / 50W With optional backplane LK1-LK2 & LK3-LK4   With optional backplane for DS-6 PA Control I & II   The compact amplifier, which was developed in a very compact design, serves to amplify the power of Neumann Elektronik DS-6 systems and also offers connectivity to all voice communication centres with an analogue interface. Thanks to different operating voltages, flexible use is possible. A special field of application is the public address and alarm system for small areas and fire compartments in office buildings, warehouses and storage areas, production environments, building yards and factory yards. The amplifier can be operated with the output voltages 50V and 100V. The switching of the output voltages is done by soldering or plug-in jumpers Transformer balanced inputs Functions according to the DIN EN 60849 regulation Volume can be set separately for day and night operation Low distortion factor ≤ 0.5% Treble and bass control Electronic, temperature-dependent switch-off from 85°C ±3K Front panel LED indicators for the following functions: Power control ,,Amp.-ON“ Ground fault ,,Gnd.-Fault“ Interruption of the loudspeaker circuit Overload or short circuit ,,Overload“ High temperature Blown fuse General fault ,,Fault“ Signal level indicators for input and output ,,In“ and ,,Out“ Galvanically free switch-on Mandatory call-in for loudspeaker Switchable input sensitivities Speaker protection through active high-pass filter Attenuators for different input voltages No-load safe and short-circuit proof Accessories   Amplifier backplane speaker circuit 1-2 Amplifier backplane extension speaker circuit 3-4 Amplifier backplane for DS-6 PA Control Compact amplifier 100W Compact amplifier 25 / 50W
