FIELD: information technology.
SUBSTANCE: invention relates to means for transmitting audio data through an audio interface. In this device, a first terminal connected to an output audio interface signal terminal device generating uplink channel audio signal by a first circuit and a second terminal - via a second chain. First conclusion is an audio interface output of a microphone or a grounding terminal and the second terminal is an audio interface output of a microphone or another grounding terminal. First and second circuits are attenuators.
EFFECT: technical result is to enable uplink transmission for audio.
