FIELD: hydroacoustics.
SUBSTANCE: invention relates to hydroacoustics and can be used in hydroacoustic systems (HAS) of sonar modes for exciting hydroacoustic phased antenna arrays (PAA). Multichannel generator device contains three groups of channels for amplification of excitation signals in three directions of phased antenna arrays of hydroacoustic complex, digital signal generating device, in which groups of amplification channels are divided into subgroups with decentralized power supply from the voltage of the object AC network through key voltage converters in the channels of the n-channel power supply device with possibility of realization of control mode of low power from secondary voltage converter through unit of multichannel diode decoupling.
EFFECT: improving reliability and energy efficiency at reduction of dimensions of transmitting equipment of hydroacoustic complex.
