Many people believe that indoor and outdoor stage audio equipment and systems are the same. In fact, due to different venues, the stage audio often used will be different. Therefore, the same solution cannot be used to configure different stage audio. Today, let’s talk about some requirements for outdoor stage audio. Of course, specific issues need to be analyzed in detail. These requirements only apply to the audio configuration of most indoor stages.
6 outdoor stage audio six major technical requirements
1. The audio system must have a strong power reserve: outdoor open-air sound field needs to have strong power, because the outdoor sound field needs to increase the sound pressure level of 3db, the power needs to be increased by 10 times. According to formula 10logp2 /p1 =xdb, the specific value of the sound field can be calculated.
2. Speakers must be hoisted: The placement of outdoor performance speakers should not be too low. The sound waves of low-level speakers are easily absorbed by the audience's body, resulting in a grazing sound absorption phenomenon, especially the loss of medium and high audio. Therefore, it is necessary to install the speakers by hoisting the speakers, midrange or treble horns and outdoor special speakers (the speakers are equipped with high-power treble horns). In this way, the sound waves of the speakers radiate far away in the air, so that the audience can get enough loudness.
3. Choose high sensitivity mic, which can enhance the sound transmission gain of mic and enable the audience to get enough loudness. Outdoor performances often have a long distance between the MIC and the mixer , so it is best to choose a wireless MIC for sound pickup.
2. Protect the power supply line: The energy of the speaker system comes from the power grid circuit. If the power supply circuit fails, the audio system will have problems. Therefore, the power supply circuit should be technically guaranteed by local professional electricians. The entire line mixer to the indoor switch or temporary power generator should be protected by special security personnel.
3.
5. Protect the speaker line: The distance between the outdoor performance power amplifier and the speaker is generally far. In order to prevent the speaker line from being broken and short-circuited, causing failure and damage to the amplifier, there must be a dedicated person to protect the speaker line. The output impedance of the power amplifier is very small, only a few ohm , but the sound power is very large, so the current is relatively large. The distance of this line is not easy to be too long, and the cutoff area should not be too small to avoid unnecessary sound power loss. If conditions permit, the power amplifier can be placed near the speaker to reduce unnecessary loss.
6. The speaker should keep in touch with the assistant in the auditorium through the walkie-talkie, so that the speaker can more accurately and timely grasp the audio effects of the auditorium, so that the adjustments can be made in a timely manner.
You can see that due to the spacious venue, the stage audio technology selected is mostly applicable to outdoor occasions, especially some audio systems. This type of audio system is used indoors, and the sound effect may be very poor. Nowadays, there are more outdoor performances, stage audio.
