The Idel-001-stereo stereo set-top box, presumably since 1984, was experimentally produced by the Kazan Computer Plant.
MP provides recording of mono and stereo phonograms with subsequent playback through UKU with speakers and through stereo phones.
The model employs: electronically controlled LMCs with automatic tape tension in the rewind and stroke modes and electronic braking, which increases the reliability of the MP and allows you to increase the life of the magnetic tape;
glass-ferrite magnetic heads, which differ from the usual ones by increased wear resistance;
electronic-logical device for controlling operation modes in any sequence, bypassing the Stop function.
The possibility is provided for: performing stunt recordings by mixing the signal from the Microphone input and any other input, or by repeatedly dubbing from one track to another with simultaneous overlay on the previous phonogram;
new recording from the microphone input;
automatic stop at the end of the tape;
control the recording level on the arrow indicators;
remote control of the "Stop", "Pause", "Rewind", "Rewind", "Play" modes when the tape moves to the left, "Play" when the tape moves to the right, with separate volume control on both channels;
selection of any operating mode, bypassing the "Stop" mode;
playback of recordings 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.
The noise reduction system reduces the level of interference during playback.
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 device comes with two coils, including one with magnetic tape.
Type of tape A4416-6B.
Coil Number 18;
27. The speed of the magnetic tape is 19.05 cm / s and 9.53 cm / s.The maximum recording or playback time is 2x45 minutes.
and 2x90 min.
The operating frequency range is 31.5 ... 22000 Hz (planned up to 28000) and 31.5 ... 16000 Hz (planned 220 000).
The knock coefficient when moving the tape from left to right is ± 0.10% and ± 0.2%, from right to left ± 0.15% and ± 0.2% (0.08 was planned).
Harmonic coefficient on the linear output of 1.5%.
Relative noise and interference level in the Z / V channel without noise reduction system minus 60 dB, with UWB minus 68 dB.
Power consumption 180 watts.
The dimensions of the device are 500x500x220 mm.
Weight is 30 kg.
