Tape recorder-set-top box `` Idel-001-stereo ''.
Reel-to-reel tape recorders, stationary.Reel-to-reel tape recorders, stationaryStereophonic tape recorder-set-top box "Idel-001-stereo", presumably since 1984, has been experimentally produced by the Kazan computer plant. MP provides recording of mono and stereophonic phonograms with subsequent playback through the UCU with the AU and through stereo telephones. The model uses: CVL with electronic control and automatic tape tension in the modes of rewinding and working stroke and electronic braking, which increases the reliability of the MP and allows to increase the service life of the magnetic tape; glass-ferrite magnetic heads, which differ from the usual ones in increased wear resistance; an electronic logic device for controlling the operating modes in any sequence, bypassing the "Stop" function. Possibility is provided for: performing trick recordings by mixing the signal from the Microphone input and any other input or by multiple re-recording from one track to another with simultaneous overlay on the previous phonogram; a new record from the "Microphone" input; automatic stop at the end of the magnetic tape; control of the recording level by dial indicators; remote control of the operating modes "Stop", "Pause", "Rewind to the left", "Rewind to the right", "Play" when the tape moves to the left, "Play" when the tape moves to the right, with separate volume control for both channels; selection of any operating mode, bypassing the "Stop" mode; playback of the recording on the 2nd and 4th tracks, when moving from right to left and in the "Auto reverse" mode; work in the "Amplifier" mode. The presence of separate magnetic recording and playback heads makes it possible to listen to the recorded signal directly during recording. Noise reduction system ensures that the level of noise during playback is reduced. The presence of a three-decade tape consumption meter with a reset button allows you to quickly find the necessary records and determine the tape consumption. The set of the device includes two coils, including one with a magnetic tape. Magnetic tape type A4416-6B. Coil number 18; 27. The speed of the magnetic tape is 19.05 cm / s and 9.53 cm / s. Maximum recording or playback time 2x45 min. and 2x90 min. The operating frequency range is 31.5 ... 22000 Hz (planned up to 28000) and 31.5 ... 16000 Hz (planned 220,000). Knock coefficient when the tape moves from left to right ± 0.10% and ± 0.2%, from right to left ± 0.15% and ± 0.2% (it was planned to be 0.08). Linear output harmonic distortion 1.5%. The relative level of noise and interference in the Z / V channel without a noise reduction system is minus 60 dB, with UWB minus 68 dB. Power consumption 180 watts. The dimensions of the device are 500x500x220 mm. Weight 30 kg.
