Stereo tape recorder set-top box '' Electronics TA1-003 ''.
Reel-to-reel tape recorders, stationary.Reel-to-reel tape recorders, stationaryThe Stereophonic tape recorder-set-top box "Electronics TA1-003" has been produced since 1979 by the Fryazinsky plant "Rhenium" at NPO Istok, and since 1980 by the Kirov Electric Machine Building Production Association named after Lepse. MP with a through channel "Electronics TA1-003" is designed for high-quality recording of phonograms on magnetic tapes such as A4409-6B and A4309-6B with subsequent or simultaneous playback through an external amplifier from speakers or on stereo phones. This model is distinguished from similar devices of the highest class by its block-modular design, widespread use of electronic commutation and high automation of the 3-motor CVL unit. The MP has: an automatic control system for the leading direct drive motor; device for electronic braking; tension stabilization system for magnetic tape in all operating modes; photoelectric hitchhiking. The following modes are available: forward and backward playback (reverse); fast rewind of the tape in both directions; "Record"; "Stop"; "Pause"; "Rollback". Transfer from one mode to another is carried out by an electronic device with pseudosensory control, which excludes deformation of the tape when the button of the selected mode is pressed, bypassing the "Stop" button when several buttons are accidentally pressed and in other cases. There is: a noise reduction system operating in a through channel; 4-digit tape counter with an autonomous sensor; gas-discharge indicator of recording and playback level; wireless remote control with connection of stereo telephones. MP is assembled on 40 microcircuits, 132 transistors, 80 diodes, 4 optocouplers and 2 triacs. Brief characteristics: coil diameter 270 mm; CV speed - 19.05; 9.53 cm / sec; detonation coefficient at a belt speed of 19.05 cm / sec - ± 0.08%, 9.53 cm / sec - ± 0.15%; operating frequency range on the LP at a tape speed of 19.05 cm / sec - 31.5 ... 22000 Hz; 9.53 cm / s - 31.5 ... 16000 Hz; relative level of interference in the playback channel -53 dB; recording / playback -62 dB; reduction of the relative level of interference when the UWB is turned on to 8 dB; harmonic distortion 1.2%; nominal signal voltage on the LV - 0.4 ... 0.6 V; nominal output power of amplifiers of stereo telephones at a load of 8 Ohm - 1 mW; power consumption 130 W. MP dimensions - 491x220x456 mm, weight 27 kg.
