What are the precautions for stage sound debugging?

The audio equipment specialized for stage performances is collectively referred to as stage sound, and stage sound is an important branch of performance equipment. There are two evaluation criteria for the sound quality of professional stage performances, the first is the objective standard, that is, the instrument testing standard; The second is the subjective evaluation criteria. Among them, the instrument testing standard (that is, the objective standard) is clear,The subjective standard is different from person to person,Therefore, first of all, it is objectively necessary to detect good performance,It is a good speaker and foundation,Of course, the subjective evaluation should be based on"Good resolution (**High resolution)"、Strong sense of vividness (**Lively performance)"、Good imaging (sound cohesion, good positioning)", "air sense (good elasticity)", high transparency (good treble penetration)".

A few precautions for stage professional audio debugging.

The debugging work of the sound engineering needs to be treated with a serious and responsible attitude, only after the design, construction, system structure and equipment performance are fully understood, in order to get a better debugging result, for the problems that often occur in the general debugging work, here we introduce to you a few technical links that should be paid attention to when debugging, for your reference.

Before commissioning, we must carefully understand the system structure and the performance of the equipment, because only by fully grasping the situation of the system and equipment, we can formulate a feasible debugging plan according to the actual situation, in order to estimate the situation that may occur during commissioning, otherwise, the system and equipment are not familiar with the situation and blind debugging, and the results will definitely not be ideal. Especially for some new and special equipment that we rarely use in general engineering, we must carefully study its principle, performance and operation methods before installation and commissioning.

Before commissioning, it is necessary to conduct a comprehensive inspection of the setting of the system and equipment. Because the focus of the installation and stand-alone inspection process and system debugging is different after all, the setting of the equipment is often arbitrary, and some important setting buttons may be completely different from the actual requirements before commissioning, so it is necessary to conduct a comprehensive inspection, and it is best to make a record of the setting of each equipment.

The corresponding debugging method should be adopted according to the characteristics of the system. Because the system index requirements of the sound and lighting project may be different, and the equipment involved is not the same, if the general engineering debugging method is blindly debugged, the result will definitely not be ideal. For example:

A sound system without a feedback suppressor, if you do not refer to the design results during debugging, only rely on the method of long-term high-gain sound reinforcement to find the feedback point, which may lead to damage to the speaker.

It's best to try the tone first.

1 Network Adapter Debugging:

Check physical connections: Make sure that the network adapter is properly connected to the computer and that the physical connection to network devices (e.g., routers, switches) is working.

Configure IP address: Configure parameters such as the IP address, subnet mask, and gateway of the adapter based on the network requirements. IP addresses can be obtained manually or using Dynamic Host Configuration Protocol (DHCP).

Test the network connection: Use a network tool (such as the ping command) to test whether the adapter is able to communicate with other devices to ensure that the network connection is working.

2 Amplifier Debugging:

Physical connection check: Make sure that the input and output of the amplifier are connected correctly, including the audio source input, speaker output, power supply, etc.

Adjust the volume and equalizer: Adjust the volume and equalizer settings of the amplifier according to your needs, and make sure that the audio output meets expectations.

During commissioning, it is recommended to refer to the user guide of the relevant equipment or contact the equipment manufacturer for detailed commissioning steps and guidance. In addition, if you have specific questions or confusion about debugging, you can also consult a professional audio engineer or network engineer for help and support.

First of all, it is necessary to formulate a series of equipment maintenance and maintenance, commissioning plans and institutionalize them according to the characteristics. Then, according to the established plan and system, specific regular maintenance work is carried out in earnest. Finally, all the work should be carefully inspected, and if there is a problem, it should be reworked immediately according to the specification.

Secondly, it is necessary to train all employees in audio knowledge and daily operation. Let's talk about equipment maintenance first, equipment maintenance should be carried out regularly planned maintenance and daily general maintenance.

Planned maintenance means to carry out weekly or monthly large-scale maintenance work according to local conditions, such as dust removal, testing, and checking whether each cooling fan has aging phenomena on system servers, song library servers, switches, integrated wiring, etc. Nip some glitches in the bud.

Daily maintenance is the work to be done every day just after going to work, microphone, microphone line, power amplifier, workstation, speaker, song panel, etc. In addition, each group of guests leaving the venue is inspected once.

Let's talk about sound tuning. It is difficult to do this work well, but as long as you master the method and do it consistently, even the most difficult problems will be solved. This is a more systematic and complex task.

It is necessary to debug room by room according to the size, space, structure, decoration, etc. of different rooms. In the time when there is no reception, try to sing some songs of different styles, and tune while singing, you can adjust some such as microphone volume and high and low pitch, ** volume and high and low pitch, reverberation size time and depth, etc., until you feel that the microphone is beautiful and pleasant, and the microphone singing is full, powerful, relaxed and natural. Generally speaking, it will be easier for the microphone volume to be slightly greater than the ** volume.

And ask some colleagues or friends who are good at singing to audition together. When everyone agrees that the effect is good, the parameters are set and marked. Generally, the reception will take these as standard sound effects, and when the guests have objections, they will be personalized according to the requirements of the guests.

However, after the guests leave the venue, they must return to their own standards, so that the acoustics of each box have a standard that is recognized by more people, and there will be no chaos.

In addition, when you go to work every day, you should also check the sound effect together with the daily maintenance, so that every day and every time it is a truly trouble-free equipment, and the best sound effect receives every group of guests. In addition, when adding new songs, don't go to the video store to buy VCD discs, most of them are pirated, and the genuine ones are very slow. The accompaniment of pirated songs either has no low mids or repeats a phrase all the time.

Adding such a song to the song library is like falling into a grain of mouse feces in rice, and no matter how good the sound is, the effect will be greatly affected. In short, making a plan, organizing and implementing, and checking and giving feedback are the three steps of maintenance and commissioning, but at the same time, they should be combined. I believe that our work will get better and better.

There are many reasons why the sound effects are bad.

First of all, the landlord should explain that the debugging of the brand and model of the equipment is a means to give full play to the ability of the equipment, and the premise is that the equipment itself must have good quality. The method of debugging is to talk about experience, and the landlord also needs to explain that the equipment needs to be adjusted.

There are two types of audio mixers: digital mixers and analog mixers. In the past, analog mixers were used more often. In recent years, digital mixers have developed rapidly.

We've been teaching for over a decade.

Professional tuners should use it. That's more professional! Systematic training some. The technical level has improved, and the sound engineer will be more professional in the future.
