AMPLIFIER-CONVERTER Russian patent published in 2024 - IPC H04S5/00 H03F3/181 

FIELD: physics.

SUBSTANCE: invention relates to analogue audio equipment. Result is achieved by the fact that to the input of the first band-pass filter of the device are connected the inputs of five more band-pass filters, which together form a block of band-pass filters, also, in each of the two-channel converter channels, five series-connected matching unit and phase-shifting unit are introduced, wherein the input of the first matching unit of the first conversion channel and the input of the first matching unit of the second conversion channel are connected to the output of the first band-pass filter, input of the second matching unit of the first conversion channel and the input of the second matching unit of the second conversion channel are connected to the output of the second band-pass filter, input of the third matching unit of the first conversion channel and the input of the third matching unit of the second conversion channel are connected to the output of the third band-pass filter, input of the fourth matching unit of the first conversion channel and the input of the fourth matching unit of the second conversion channel are connected to the output of the fourth band-pass filter, input of the fifth matching unit of the first conversion channel and the input of the fifth matching unit of the second conversion channel are connected to the output of the fifth band-pass filter, the input of the sixth matching unit of the first conversion channel and the input of the sixth matching unit of the second conversion channel are connected to the output of the sixth band-pass filter, wherein the combined six outputs of the phase-shifting filter units of each of the converter channels form a single output of the converter channel, which is connected to the input of one of the amplification channels.

EFFECT: high quality of listening to monophonic signals.
