Radio constructor `` Olymp-2 '' (Preamplifier with tone block).
Radio and electrical constructors, sets.Audio AmplifiersRadio designer "Olimp-2" (Pre-amplifier with a timbre block) has been producing Vinnitsa Central Design Bureau since 1980. The preamplifier with the `` Olymp-2 '' tone block, which can be assembled from a set produced by the plant at the Central Design Bureau of Information Technology in Vinnitsa, in Ukraine is designed to work together with the `` Olymp-1 '' power amplifier or any other similar amplifier with a sensitivity of at least 250 mV. The sensitivity of the amplifier from the microphone input 1 ... 2 mV, from the input for the receiver 20 ... 40 mV and from the input for connecting a tape recorder 200 ... 250 mV. Operating frequency range 20 ... 30000 kHz. The voltage of the low-frequency signal at the output is about 250 mV. The depth of tone control at frequencies of 100 Hz and 10 kHz is not less than ± 15 dB. The preamplifier is powered from the Olimp-3 unit or any other unstabilized bipolar source with a voltage of 18 ... 20 V. The total consumed current of the preamplifier is about 50 mA.
