FIELD: wire broadcasting technology. SUBSTANCE: device has two channels. Each of the channels consists of information source connected to linear amplifier. Output of first channel linear amplifier is connected to wire broadcasting amplifier through wire communication line. Output of second channel linear amplifier is connected to transmitter input through wire communication line. Outputs of transmitter and of wire broadcasting amplifier are connected to inputs of summer. To increase number of transmitting channels, device is provided with auxiliary information source connected to input of other transmitter connected to input circuit of second channel linear amplifier. Device has also matching device, connected with its leads to wire communication lines of second and first transmitting channels, and receiver the input of which is connected to summer output and its output, to personal computer. EFFECT: more effective information transmission. 4 cl, 5 wdg
