Low frequency amplifier `` Electronics-10-stereo ''.
Radio and electrical constructors, sets.Audio AmplifiersThe low-frequency amplifier "Elektronika-10-stereo" (Constructor) has been produced by the Vinnitsa plant "Oreol" since 1983. The designer is based on the improved circuit solutions of the "Olymp" amplifiers. A more modern element base is used in it, a number of design improvements have been made. Both preamplifier channels are now located on the same PCB, greatly simplifying amplifier layout. The advantageous difference between Electronics-10-stereo and similar products is that it has protection of loudspeakers from constant voltage. The same node provides a loudspeaker connection delay to eliminate the click when the amplifier is plugged in. The circuit and design of the amplifier also provides for the connection of output level indicators such as M-478 or M-476. The indicators can be installed on the front panel on the right, above the volume controls. Rated output power at a load of 4 Ohm 2x10 W. Frequency range with uneven frequency response no more than ± 1.5 dB 20 ... 20000 Hz. Harmonic coefficient no more than 1%. Sensitivity from the input microphone 2 mV, radio 25 mV, universal 200 mV. The depth of the bass and treble tone control is ± 15 dB. The amplifier is powered from a 220 V network. The set price is 70 rubles.
