Reel-to-reel radio tape recorder `` Miniya-4 ''.
Tape recorders and radio tape recorders.The reel-to-reel radio tape recorder "Miniya-4" has been producing the Kaunas Radio Plant since 1966. The first-class radio tape recorder "Miniya-4" consists of an eight-lamp receiver of the first class and a two-speed tape recorder "Vilniale", representing a tabletop structure made in a case made of wood with a finish imitating valuable species. Some of the radio tape recorders were equipped with removable feet for installation on the floor. The front of the speaker was made with a plastic or wood trim. In the plastic version of the design, the radio tape recorder and the cover of the tape recorder panel were made of plexiglass. There were fewer such options than those made of wood. In plastic, the dimensions of the radio are 826x380x390 mm. The speaker system consists of two side loudspeakers of the 4GD-28 type and two frontal 1GD-28 in the version with a plastic cover or two side loudspeakers 4GD-28 and one front 1GD-28 in the version with a wood cover (1st and 2nd variants ). In the radio tape recorder, a block of tone registers is used for three positions "Orchestra", "Solo" and "Speech", which allows you to choose the sound timbre that better matches the received program. There are smooth tone controls for the lowest and highest sound frequencies. The radio receiver is designed to receive radio stations in the ranges DV 150 ... 208 kHz, SV 525 ... 1605 kHz, KV 9.36 ... 12.1 MHz and 3.95 ... 7.4 MHz and VHF-FM 65.8 ... 73 MHz. Sensitivity in DV, SV ranges 40 ... 60 μV, KV 60 ... 80 μV and in VHF-FM - 10 μV. Selectivity on the adjacent channel on all bands except FM 55 ... 70 dB, the slope of the resonance characteristics in the VHF range is 0.22 dB / kHz. In the IF path of the receiver there is a smooth bandwidth control with a fixed position `` local reception ''. The "Vilnjale" tape recorder panel, 2nd class, allows you to record sound from a microphone, radio, radio, turntable, TV or any other source of the sound program. The tape recorder is designed for two-track recording on a magnetic tape of type 6. You can also use tape of type 2, but the quality of recording and playback will deteriorate. The duration of recording when using spools with a capacity of 350 meters of tape is about an hour at a speed of 19.05 cm / s, and about two hours at a speed of 9.53 cm / s. The duration of rewind and fast forward is 3.5 minutes. The "Vilniale" tape recorder (there were 2 designs) has a universal amplifier with an erasure and bias generator. Rated output power 1.5 W, maximum 3 W. The power consumed from the network is 85 W when receiving and 125 W when operating the MP. The radio tape recorder "Miniya-4" in two versions was also produced in two versions of inscriptions on the scale and the back wall, in Russian and Lithuanian.
