Magnetoradiola `` Romance-104-stereo ''.
Combined apparatus.Magnetoradiola "Romance-104-stereo" since 1971 has been experimentally produced by the Kharkiv PSZ im. Shevchenko. The installation consists of a 1st class receiver "Riga-101", a four-track tape recorder, an EPU of the 2nd class II-EPU-32S and a stereo acoustic system. The receiver is designed to receive in the ranges: DV, SV, KV-1 3.95 ... 5.75 MHz, KV-2 5.65 ... 7.4 MHz, KV-3 9.4 ... 12, 1 MHz and in VHF-FM, where the reception of stereo programs is carried out according to the system with polar modulation. Receiver sensitivity in the AM ranges of 50 µV and 4 µV in VHF. Selectivity in the range of DV, CB - 70 dB. AGC allows you to get a change in the output signal by 5 dB, with a change at the input of 40 dB. The rated output power of the amplifier is 2x1.5 watts. The operating frequency range for sound pressure is 60 ... 12500 Hz. The range of tone control is 14 ... 16 dB. The crosstalk between the channels is 20 ... 30 dB from the antenna and 30 ... 40 dB from the input of the LF amplifier. The EPU has 4 rotation speeds: 16, 33, 45 and 78 rpm, semi-automatic switching on and off the engine, microlift. The power consumed by the device is 80 watts. Its dimensions are 890x434x386 mm. Weight 32 kg. The portable four-track tape recorder has 2 magnetic tape speeds of 9.53 and 4.76 cm / s with a detonation of 0.3 and 0.4%. The sounding time of a stereo recording at a higher speed when using reels No. 15 with a tape of type 10 is 2x65 min. The operating frequency range is 60 ... 12500 Hz at a speed of 9.53 cm / s, 60 ... 6300 Hz at a speed of 4.76 cm / s. The noise level of the recording-playback channel is not worse than -42 dB. The tape recorder has separate jacks for connecting a microphone, a pickup, a receiver and a broadcast line, the commutation of which is carried out by a push-button switch. The sensitivity from the microphone input is 0.6 mV, the pickup is 250 mV, the radio receiver is 50 mV and the transmission line is 30 V. Separate recording indicators, a pause device and a three-decadal counter make the device convenient to use. MP has a 127/220 V power supply unit. Power consumption 40 watts. The weight of the attachment is 12 kg, dimensions are 420x320x170 mm.
