Spring-101-stereo stereo cassette recorder.
Cassette tape recorders, stationary.The "Spring-101-stereo" stereophonic cassette recorder was experimentally produced in 1980 by the Iskra Zaporozhye Electric Machine Building Plant. It is made on the basis of the LPM tape recorder-set-top box `` Spring-001-stereo '' and works with a magnetic tape made of iron oxide and chromium dioxide. The model has a switchable dynamic noise reduction system with an adjustable response threshold, auto-stop at the end of the tape, a three-decade counter for the consumption of magnetic tape with memory mode, a six-band tone control. In addition, it is possible to connect various signal sources for playback through the amplifiers of the tape recorder and its external speakers, there is a light indication of the type of magnetic tape, recording mode, peak overloads, in recording and playback modes. The "Spring-101-stereo" tape recorder operates on two "35 AC-1" acoustic systems. Belt pulling speed 4.76 cm / sec. Knock coefficient 0.18%. Rated output power - 2x20 W. The operating frequency range at the linear output when using a magnetic tape based on chromium dioxide is 30 ... 18000 Hz, iron oxide is 40..12500 Hz. Reducing the noise level when you turn on noise reduction 8 dB. The dimensions of the tape recorder are 485x395x140 mm. Its weight is 18 kg.
