Further information for RCS Audio-Systems DBA-250D - 1 Channel Power Amplifier (375/250 2 U) digital IEC 268 5
Description
With these digital amps 100 V we also make a major contribution to the overall trend of sensible energy use, thereby protecting the climate and our environment. The advantages of digital amplifiers to justify the much higher efficiency of about 90% compared with analog amplifiers with about 70%. The out come of that lost heat is much lower, which has a positive effect on the durability of the amplifiers and of course on the complexity of the cooling from 19?-Centers. Additional cooling of the art room is not necessary.
Features
Pilot tone and fault signal contacts for emergency power and power amplifier make these amplifiers for PA installations in accordance with VDE 0828 60849th
If no signal is present, the amplifier automatically goes into standby mode and consumes only max. 9.9 W when the signal is pending, eg alarms, the amplifier 30 ms is ready.
Amplifiers are manufactured by modern production methods with high quality components and are therefore very reliable for continuous professional use in PA-alarm systems.
The battery capacity for emergency power operation is significantly lower than in analog amplifiers.
output power and protection circuits according to IEC 268-5
inform the LEDs on the front page of important signaling and operating conditions.
Cooling is maintenance-free fanless, which means no pollution, no . follow-up costs and therefore especially suitable for noise-sensitive facilities (offices, churches, conference rooms, etc.)
Special protective circuitry against open circuit, short circuit, over temperature and a switch are standard.
Additional features:. shallow installation depth of only 260mm and recessed volume control
The units feature speaker outputs -., and balanced inputs on screw-type, thereby substantially reducing the wiring
Inputs can optionally be equipped with input transformers, please order in this case simply per input option TSE 203.
