Color music devicesColor music devicesSince 1978, the Spectrum-10 color music prefix has been produced by the Oryol Plant UVM named after V.I. K.M. Rudnev. CMP serves for color accompaniment of sound reproduced from a tape recorder and an electrophone. In the amplifying path, the signal is divided into 3 frequency bands. The generated signals control the glow of three groups of incandescent lamps, which are equipped with colored glass filters - red on the bottom row, green on the middle and blue on the top. The light from the lamps passes through a common diffuser and the colors are mixed. In order for the color shades to appear more prominently, the prefix should be installed in the least lit corner of the room. Number of main channels - 3. Maximum power consumption - 450 watts. Power per channel - 75 watts.

Number of illumination channels - 1. Illumination channel power - 25 W.
