Sound engineer: the secret to creating a perfect sound quality for a concert

Can you imagine your idol using a radio microphone with an unstable sound, through the occasional squeaky noise speakers, in an echoing venue, say "I love you" to the audience under the stage? To create a perfect concert, you must have two key factors. First, you have good audio equipment and use them. The second is to combine the reasonable sound of the concert venue.
Because poor sound quality is usually uncontrollable, it is still necessary to solve this problem, otherwise it is irresponsible to the audience. "Let us control things that we can't control, and try to solve them!" Of course, sometimes it's a device problem, but more often the people who operate the device mess up the sound quality.

Let's take a look at the main elements that determine the perfect sound quality of a concert:

Sophisticated stage sound equipment

If the sound reinforcement device does not cover the entire location, you can find more speakers or re-adjust the speaker position for best results. For example, once in a theater with three floors, the local staff said that the existing sound reinforcement equipment could not cover the third floor. He adjusted the position of the speakers to make the bottom and the second and third floors. Can get a good sound effect, which is a reasonable compensation measure. Then, based on the existing sound reinforcement equipment, some additional mid-high-pitched sound speakers that are aligned with the third floor are added, and the desired effect is achieved.

Good acoustic condition

With good equipment and equipment, it does not mean that the sound problem of the performance is solved. The venue actually has a particularly large impact on the acoustics of the show. Most of the popular shows are held in sports venues, but in fact the stadium or stadium is the least suitable for music. How to deal with the sound system in the stadium is a big challenge and test for the sound engineer. A successful sound design should be to let the audience at all locations in the venue hear good sounds.

Proper use of wireless microphones

Due to the design and expected results, the working state of the wireless microphone works according to "witchcraft", so some people will say "I can't do anything". But the actual situation is that there are almost always measures that can be taken, which should be treated scientifically, and the principles of physics are working. However, if the wireless microphone used is of poor quality, the chances of achieving good results are very low. But as long as you can spend four hundred dollars or more on each channel, the rest is only the problem of antenna design and frequency selection.

Reasonable investment

Since the equipment is involved, it will inevitably involve investment problems. Liu Yu, a sound engineer who was responsible for Xu Wei’s “Out of Print Youth” concert in Beijing, rarely took over in recent years. One reason for keeping him away from the show is that the organizers are too harsh on the audio investment. He said: "To be a performance, investors want to minimize costs, but artists and tuners hope to use the best equipment to make the best sound. This is actually a very contradiction." In other words, we have world-class equipment, but there is not always a commensurate capital investment for our sound engineers to enjoy these devices.

From the artist and the production unit to the audience and the media, every aspect of the performance should be emphasized. Although the problem of sound is not as strong as the sensory stimulation brought to the audience by visual performance, it is one of the most basic factors to measure the success or failure of a popular concert. After all, in popular music performances, we first went to the music of the singers, and the visual performances were just the decorations they made to enhance the appeal of the music.

Star concert tuning equipment classic case

As mentioned above, audio equipment is very important for a concert. In fact, it is not enough to equip good equipment. There must be an excellent tuning equipment to present the perfect technical performance of all equipment. Here are some of the tuning devices that are popular with star concerts.

Xu Wei 2009 Beijing personal concert live sound is still played by the domestic master figure Jin Shaogang, and used the Venue live digital mixing console.

Song Zuying teamed up with Domingo, Jay Chou and Lang Lang's "Charming China" Beijing Bird's Nest Summer Concert to sing and sing. This concert is escorted by the world's most famous MIDASXL8, PRO6 and H3000 mixers; The recording uses KLARKTEKNIK's latest DN9696 high-precision audio workstation.

Zhang Xiaohan, the "outside star witch" of the new generation of singers, performed his first personal concert, especially using Digidesign's large-scale live mixing console VENUE as the FOH console for the concert.

MTV held the 2nd African Music Awards Ceremony, and the rental company Audio Broadcasting Service (ABS) in Rastatt provided two mc256 hybrid mixers, both for mixed broadcast and mixed separate music. The device features a 64-fader stereo panel that is fully programmable in the 32-16-16 configuration.

The "long line" band composed of Luo Dayou, Li Zongsheng, Zhou Huajian and Zhang Zhenyue, the last concert in Sichuan, the famous tuner Jin Shaogang carried his favorite VENUED-show live mixing digital mixer.
