Car radio `` A-5 ''.
Car radio and electrical equipment.Car radio and electrical equipmentSince 1952, the automobile radio "A-5" has been producing the Murom radio plant. The A-5 receiver is a 6-tube superheterodyne and is designed for installation in ZIL-110 and ZIM (GAZ-12) vehicles. It was produced in 2 versions, powered by 6 and 12 V batteries. Power supply of the anodes of the lamps from a vibration transducer. The receiver together with a loudspeaker and a power supply unit is assembled in a common housing. An additional loudspeaker was located in the rear of the car or behind a partition. The receiver is tuned by changing the inductance of the coils, by moving the cores from the alsifer. Inductors together with a push-button switch, power switch, volume and tone controls are made in a separate unit. A scale with conventional graduations in the form of uniform divisions and is illuminated from the ends, its color changes depending on the position of the tone controls with the help of color filters mounted on the axes of the same controls; red emphasizes the high frequencies, green lows, white indicates the reproduction of the middle frequencies of the audio spectrum. Technical parameters: Frequency ranges: DV 150 ... 410 kHz, SV 530 ... 1450 kHz, KV1 6 ... 6.25 MHz, KV2 9.5 ... 9.7 MHz, KV3 11.7 .. .11.9 MHz. IF 465 kHz. The sensitivity of the model is in the LW range 200, SV 50, in the KV range 40 µV. Adjacent channel selectivity 28 dB. On the mirror image 34 dB at LW, 40 dB at MW and 34, 30, 20 dB, respectively, on the HF subbands. The range of reproducible frequencies is 80 ... 5000 Hz. Output power 2 W. Power consumption 53 W.
