Around 1932, the plant focused on the production of acoustical-electrical transducers, microphones and loudspeakers, and their first prototype tuned radio frequency receiver was produced that year.

In 1946 the plant adopted the name Oktava (meaning "octave"), and in 1948 they began production of a 100-watt loudspeaker, the first batch of which were installed in Red Square, Moscow.

In 1957, Oktava small telephones and moving coil radial loudspeakers were displayed in the Russian section at the 1958 exhibition in Brussels.

From 1964 Oktava began implementing a "zero-defect" production system, and their TM-4 miniature telephone and ML-16 ribbon microphones received state quality marks.

During this period Oktava was providing equipment for Kremlin meeting rooms and Ostankino Technical Center, the state's biggest TV studio.
