Currently, corporate meetings typically include local meetings and remote video conferences. Sound is often a key factor in the quality of any meeting. In conference rooms, sound reinforcement systems, multimedia systems and equipment are very complex. For better meeting sound, microphones, speakers, mixers and amplifiers, and conference room audio equipment cannot simply be stacked on top of each other. Here we will give you a detailed summary on how to debug your audio device.

1. Check whether the system is connected correctly.

The correct connection of the system is the basis for satisfying audio debugging. According to the system configuration connection diagram, carefully check the line connection and power supply system, preset the function buttons of the audio equipment, and ensure that the microphone has enough power.

Second, adjust the position of the speaker.

The main speakers should be placed on both sides of the conference stage, with woofers at the bottom, midrange speakers in the middle, and tweeters at the top. If the radiation areas of the two speakers echo each other, the sound quality will be greatly improved. Do not place potted plants, table lamps or porcelain figurines on the speaker. Otherwise, meetings may be interrupted when objects are dropped due to speaker vibration. Multimedia conference audio

Third, turn on the power amplifier and set the level.

After confirming that the audio system and hardware of the multimedia conference room are normal, turn on the power of the equipment, turn on the power amplifier, and set the level to high level. Turn up the mixer input gain on the mixer indicator to 0dB, slowly push the mixer output fader up, and adjust the fader according to the sound inside the cabinet for better volume. In order to ensure a good debugging effect, it is recommended to use a phase detector to check whether each speaker is in phase.

Fourth, avoid making loud noises.

Push the mixer channel's fader to 0 dB, place the mic on the conference platform, turn on the monitor output, find the frequency band where the mic is causing the noise, and adjust the EQ settings to eliminate it. The microphone should be kept away from the speaker, and the platform position can be adjusted appropriately if necessary. The working range must be small to keep the whistle at a steady level, then adjust to be more accurate. Multimedia conference audio products

The above are the steps to debug the audio device in the local multimedia conference room. In video conferencing, the choice of video conferencing equipment is more important. To avoid noise interference in video conferencing, you can choose a video conferencing brand and equipment that is equipped with audio processing technology.
