1. Connect the sound source with an audio cable. The sound control station in the hotel venue is provided with a sound output port, which can be a single channel or a monitoring channel, and is connected to the live broadcast station as a sound source through an audio cable. The length of the audio line can be determined according to the size of the venue.
2. Use a sound card. Collect the received sound and transmit it to the computer through USB. You can choose a sound card with noise reduction effect, and you can add a mixer if you have professional needs.
3. Use the camera to receive the broadcast directly. The direct video acquisition box transmits the video and sound of the camera together. Because the venue is noisy, this method is generally not recommended. When there is a problem with the sound access of the mixer, we can consider extracting the camera sound directly from the HDMI interface as an emergency record.
