Video television equipment.video playersA cassette color video recorder-set-top box "Spectrum-203" has been produced since 1977 by the V.I. Lenin. The country's first color cassette video recorder-set-top box, Spectrum-203-Video, was developed back in 1974, but its mass production began only in 1977. The VCR is designed for recording and playback of color and black-and-white television programs using televisions equipped with a pairing device supplied with and from television cameras. The VCR uses a slant-line method for recording video information with two rotating video heads and a longitudinal method for recording sound and control signals. The information carrier of the VM is a magnetic tape with a width of 12.7 mm, placed in a special VK-30 or VK-45 cassette, the recording time on which, respectively, 30 and 45 minutes. Threading the tape into the LPM path and turning on and off the device at the beginning or end of the magnetic tape are carried out automatically. The speed of the magnetic tape is 14.29 cm / s. The detonation coefficient of the CVL is 0.25%. Video recording speed 8.1 m / sec. The band of the recorded video frequencies is 2.2 MHz. The clarity of the reproduced image is 200 lines. The frequency range of the sound channel is 120 ... 12500 Hz. The signal-to-noise ratio in the sound channel is 37 dB. The distortion factor of the sound channel is 5%. Power consumption from the network is 180 W. VCR dimensions - 560x355x167 mm. Weight 17 kg. In 1981, the plant produced an upgraded Spektr-205 video recorder, which was distinguished by more than 2.5 times longer recording time due to a decrease in the speed of magnetic tape transport, an improved signal-to-noise ratio, and a slightly higher quality of image and sound. The design of the VCR has hardly changed. The release of the Spektr-205 video recorder was limited. There is no other information on this model yet.
