Provided is a tuning and broadcasting device monitored bi-directionally, remotely, and in real time in separated networks, which features the following characteristics. A directional microphone-integrated sound pressure camera collects a sound source using ten or more directional microphones provided in an integration housing according to X-Y coordinates at a forward pointing angle. An output of the directional microphone-integrated sound pressure camera, which is a sound pressure camera matching the virtual X-Y coordinates with a front image, is inputted to a mainboard in a local network. The mainboard in the local network converts sound pressure of the sound source that the directional microphones collected from the X-Y coordinates at the forward pointing angle into a digital sound pressure value. The mainboard in the local network displays a captured image, which is produced by capturing an image after placing a color signal converted according to a respective set of X-Y coordinates to X-Y coordinates of an image taken by the pressure camera, transmits the same to a mainboard in an external network, and then transmits the same to a remote control server through a network switch which is on. The remote control server remotely controls a sound source generation device of a local control server through the image displayed on a monitor, which is the captured image in which the digital value of the sound pressure is converted into the color signal on the image taken by the sound pressure camera, and outputs the sound source as an acoustic signal tuned by an audio mixer. |
