ZR-04 broadcasting system

3D Model

The ZR-04 broadcasting system was manufactured in the 1980s. It was the final stage of communist Poland, which had an impact on the scale and methods of production of consumer goods. Society was becoming poorer, and the nation’s economy was struggling. Hence, for the electrical engineering industry, the period saw a major slowdown in comparison with the dynamic growth of the 1970s. The ZR-04 broadcasting centre comprises: cassette recorder, car radio, gramophone, and amplifier. A broadcasting centre is the core of a wired public address system. It is the source station allowing creation, broadcasting, and application of programmes. The device enables the management of a set of amplification devices embedded in the infrastructure of public utility buildings, such as schools, boarding houses, offices, railway stations, and communal life spaces like workplaces, prisons, or supermarkets.
