Conference room audio equipment operation and common problems.Shaanxi Conference Room Audio

　　1. Handling of common problems

　　Earlier, we briefly explained the operating knowledge of some audio equipment. Under normal circumstances, even if it is strictly debugged, the occurrence of faults cannot be absolutely avoided. It is necessary to constantly summarize experience in daily work and often analyze faults. In order to ensure the normal operation of the audio equipment and the success of the meeting. The following is an introduction to some common fault phenomena and solutions:

　　1. Adjustment of signal transmission

　　Large-scale conferences, such as large sites, need to configure a lot of speakers, and need to output high, medium and bass separately, as well as monitor speakers, monitor speakers, etc. If the output port of the device cannot meet the requirements, an audio distributor is needed to assign different signals to power amplifiers with different functions and adjust them one by one. The method is to adjust one pair, first turn off the other speakers, adjust them in place, and then adjust the other speakers.

　　2. The connector and connecting line are not connected well

　　Connectors and connecting lines are one of the main factors that often cause failures. The sound is sometimes absent or noisy, which often causes a performance to fail. In fact, this kind of fault is very easy to eliminate. When checking the equipment before the performance, it is necessary to check all the lines, and use a multimeter to measure the on and off of them one by one. If any problem is found, deal with it in time, and spare common connecting lines and adapters.

　　3. Main channel failure

　　When the main channel fails and cannot be played, the monitor speakers can be rotated to an appropriate angle to temporarily replace the main channel, so that the conference can continue. The microphone used for speech should have a backup, which can be replaced by a backup when the microphone is silent. The DVD player should also have a backup, which can be replaced when the DVD player fails.
