PURPOSE:To obtain an output from various AV equipments connecting to a terminal equipment in an optimum sound volume. CONSTITUTION:A sound initial data is down-loaded from a sound volume memory 13 of a hotel center computer 1 in advance to a sound initial value memory 31 of a terminal equipment 3 and transferred to a sound volume memory 3m at the transmission of check-in information. A switch S1 of a video input changeover switch 3J is closed at the reception of a TV signal, a voice changeover switch 3c, a video changeover switch 3e, and a sound volume data changeover switch 3n are connected to each terminal 1 with a microcomputer 3i and a sound electronic variable resistor 3p adjusts a level of a voice signal in response to the sound initial data from the VR 1 of the sound volume memory 3m. On the other hand, an MSX personal computer is connected to each terminal 2 of an external video input terminal 3f and an external sound input terminal 3d and when the switch S2 of the video input changeover switch 3j is closed, the three changeover switches are connected to each terminal 2 and the sound initial data for the MSX personal computer from the VR 2 are fed to the sound electronic volume 3p. |
