The radio designer "Rapri UM-1" (Power Amplifier) "u200b"u200bhas been produced since 1991.
A stereo power amplifier with a rated output power of 2x10 W is assembled on analog A2030V microcircuits.
Placed on the board: heat sink radiator with a heat sink surface of 750 sq. Cm;
radio elements;
connectors for connecting the signal source, supply voltages and loads.
A2030V is a high power amplifier, covered by negative feedback, having protection against load short circuit, with a supply voltage range from 6 V to ± 18 V. At maximum voltage, it is capable of delivering 4 Ohms to 20 W to a load.
Chips are placed on a common radiator.
The minimum EMF of the signal source is 0.7 V. Input resistance is 22 kOhm.
Nominal (maximum) output power at a voltage source ± 15 V - 10 (15) W.
The band of reproduced sound frequencies is 20 ... 20,000 Hz.
Total distortion 0.05%.
Dimensions UM - 156x108x52 mm.
The price of UM is 30 rubles.
The PA was supplied assembled, for assembly together with the preamplifier (also RC) of the full amplifier of the AF.
