Stereophonic radio complex `` Oda-102-stereo ''.
Combined apparatus.Since 1986, the Oda-102-stereo stereo radio complex has been produced by the Murom plant RIP. The complex provides reception of mono and stereo broadcasts in the VHF range, recording of mono and stereo programs, followed by playback. The complex consists of 5 functionally completed blocks; VHF tuner '' Oda-102S '', cassette tape recorder-set-top box '' Oda-302S '', power amplifier '' Oda UM-102S '', pre-amplifier '' Oda UP-102S '' and 2 acoustic systems '' '15 AC-213 ''. The complex has four fixed settings; automatic frequency control and silent tuning; LED indicators for fine tuning and reception of stereo programs; automatic switching of modes "mono-stereo"; ShP system; switch of tape types with light indication; tape consumption meter; hitchhiking at the end of the tape in the cassette or cassette malfunction; 3-band tone control, switchable loudness; stepwise attenuation of volume; LED indication of overloads; electronic short circuit protection. It is possible to connect external signals. Output power (4 Ohms): nominal 2x10 W, maximum 2x25 W. Speaker input impedance is 4 ohms. The supply voltage is 220 V. The power consumption of the tuner is 4.5 W, the tape recorder is 7 W, the power amplifier is 34 ... 100 W, the amplifier is preliminary 10 W. Dimensions of one unit: tuner, UM and UP - 223x245x75 mm, tape recorder 220x144x247 mm, one acoustic system 160x178x265 mm.
