Cassette recorders-set-top boxes '' Vilma-102-stereo '' and '' Vilma-110-stereo ''.
Cassette tape recorders, stationary.Since 1981, the Vilma-102-stereo and Vilma-110-stereo cassette recorders-set-top boxes have been produced by the Vilnius instrument-making plant "Vilma". Stationary cassette MP with a through channel "Vilma-102-stereo" is designed to work with magnetic tapes of all types in MK cassettes. The MP uses a two-motor CVL with a closed path and quasi-sensor control. The electronic part is built on the basis of specialized integrated circuits and a combined magnetic recording and playback head. The device has: indicators of average and quasi-peak signal levels, they work in the recording and playback mode; interference suppression device when switching modes; Dolby-B compander noise suppressor; tape consumption meter; her loop sampling device and hitchhiking. You can remove the cassette and turn on the required operating mode without pressing the "Stop" button. The automatic switch disconnects the tape recorder from the network in 1 ... 1.5 minutes after the transfer of the LPM to the `` Stop '' mode. There is a calibration of the recording current for the type of magnetic tape used, adjustment of the bias current, stepwise change in the signal level at the linear output, auditory control of the signal recorded and recorded on the tape. The jointly produced "Vilma-110-stereo" set-top box tape recorder is similar in scheme and design to the one described above, the only difference is in the external design, other handles and buttons. Belt speed 4.76 cm / s. Knock coefficient ± 0.17%. Operating frequency range on magnetic tape A4205-ZB 31.5 ... 14000 Hz, A4212-3B 31.5 ... 16000 Hz. Reducing the noise level of the Z / V channel when the ShP system is turned on 8 dB. The signal voltage on the LV is 250 ... 700 mV. Output power for stereo phones is 10 mW. Power consumption 50 watts. MP dimensions - 466x166x308 mm. Its weight is 13 kg. Since 1985 the plant has been producing an improved MP "Vilma-102-1-stereo". Here, a through channel Z / V and a remote control device have been added with all LPM modes on IR rays. Also improved some characteristics of MP. The operating frequency range of sound with the A4212-ZB tape is 31.5 ... 18000 Hz. Knock coefficient 0.15%. The relative level of noise and interference with UWB is minus 64 dB. Power consumption 20 W. MP dimensions - 480x168x320 mm. Its weight is 10.8 kg.
