  • ✅ The importance of designing a hall sound system

    Audiovisual technology develops over time. Over the decades, until now, every 1 year, audio manufacturers will release many new products. Will integrate many new features for the product. New features are smarter, mainly to make it easy for users to operate and exploit. However, this does not mean that old sound systems will be obsolete and unusable. In fact, a hall sound system has an average lifespan of 2 to 10 years. Depending on the original design problem, the sound system is effective and operates with quality.

    Having worked in this field for many years. We understand that the most important part of a system's effectiveness is still the design stage. System design does not mean bringing together expensive products to produce good results. The essence of the design of an audio system is to solve the logical problem for the following four factors:

    • Right for the owner's intended use
    • The device works well in space and environment
    • Simple operation, maintenance and maintenance
    • The investment cost for the system is suitable

    When designing a sound system that meets these 4 factors, the system achieves the highest investment efficiency. Therefore, showing the importance in the design of the sound system of the hall, meeting room is very important to have reasonable solutions for each project and work to ensure efficiency and minimize problems. Investment topic is not for the right purpose, not effective.

    ✅ Things to keep in mind when designing a hall sound system

    ✔ What is the purpose of sound system design?

    The hall sound system is often used for two combined purposes: meetings, summaries, and cultural and artistic exchanges. Thus, the sound system in the hall will need to ensure the above two purposes. In which each purpose will have different requirements:

    • Serving meetings and seminars: Requires a speaker system with enough power to hear clearly, antique microphones are also of good quality when speaking without echoing, ...
    • Serving cultural and artistic exchanges: Requires a relatively large capacity speaker system, needs more subwoofers to serve music, the system connects instruments so that it is convenient to serve effective performances. most fruitful.

    To meet the above two uses, the design of the hall sound system should pay attention to the following issues:

    ✔ Design the sound system corresponding to the size of the hall

    How much is the area of ​​the hall to use, how many people to design the sound for the conference, the hall accordingly? This is simple, but it will make it easier for you to consider and choose audio equipment that is capable of diffusing to all locations of the hall, avoiding buying speakers that are too loud for a narrow space. and vice versa.

    In addition to the area factor, the height of the hall should be considered. In the case of high-ceiling halls, the design becomes simple. But for halls with low ceilings below 4m, hanging high-powered speakers will not be suitable for different listening positions. The best method for low-ceiling halls is to use speakers with sufficient power and evenly spread the speakers to distribute the sound most evenly.

    ✔ Using synchronous, compatible devices, compact system design

    The audio equipment included in the design should choose the latest equipment, simple, easy to operate, easy to maintain and capable of updating new technologies. Do not use too many devices with duplicate functions. Systems should be integrated so that they are compact and easy to transfer technology.

    Note: The design of a cumbersome system is often due to a preference for numbers, but that was not really necessary and sometimes backfired for the operator.

    ✔ Interior design enhances sound dispersion, sound absorption reduces echo

    This is important for a hall with standard sound quality. Surely when the investor designs a hall, he will work with architects and sound experts. The sound engineers will consult from the very beginning for the best interior design for the sound system. The materials used for decoration are usually porous, soft, wood, curtains to reduce echo - echo occurs in the hall.

    ✅ How to invest in a good sound system with the limited cost?

    Investors often have anxiety and worry when spending money to invest in a sound system. Because sound is a product that cannot be measured immediately, its effectiveness will often result after a process of use. Most investors often believe in choosing cooperation partners to avoid risks. However, in terms of funding, perhaps they do not grasp every detail. The following content will be shared with you so that you can have more information for reference.

    ✔ Should buy genuine equipment, with the origin, CO, CQ

    You can limit the initial cost, you can buy products with cheaper prices of not too famous brands in the market, but hope you should not buy fake goods. Current audio equipment is quite diverse, the price and quality of genuine brands, including Chinese goods, if it is genuine, it is still good. Buying fake products will only save money in the short term, but most of them are made in Vietnam with poor quality. Units using counterfeit goods are often units with low reputations.

    ✔ Select reputable units in the market

    Reputable units in the market will be very careful when doing a job that can affect their reputation. You should consult the prices of these units first to get the most reasonable design. Then we will refer to similar units to choose a unit with a good price with similar equipment.

    ✔ Select devices that are just enough for the purpose of use, meeting the basic requirements well

    When funds are limited, you should list the main purposes to use. Let the design and consulting units be suitable for the main purposes first. Then the secondary purposes will be prioritized later. Normally, the budget package is limited, if one factor is met, the other factor is reduced. Need to go to the heart of the work, reduce redundant or unnecessary equipment for later investment. You ask the consultant to choose the equipment as neat as possible. The goal here is to achieve the requirements without being too expensive, redundant.

    ✅ What are the specialized audio equipment used for the hall?

    Below are the commonly used auditorium equipment, we arrange them in descending order of importance as follows:

    ✔ Full/Line Array speaker system Main speaker for hall

    Main Speaker (Full Speaker) is the most important piece of all audio systems. This is the device used to distribute the main sound to the audience hall below. Full speakers usually have 2 types: Full Line Array and Full wall mounted. For halls with large numbers, usually choose Line array speakers (requires high ceilings) that can be hung high to evenly cover the hall space. Wall-mounted speakers are often used for halls with a small area, or with low ceilings, which will be evenly distributed around the hall. In current full speakers, there is a built-in Amplifier and DSP line inside the speaker called Active Line Array. This Active speaker system makes it very simple to design and operate a sound system.

    ✔ Mixer, audio mixer

    The mixer is the heart of the system, currently, the Digital Mixer line has been very popular on the market to replace traditional mixers. Digital mixers incorporate a variety of technologies that make operating a system simple and uncluttered.

    ✔ Amplifier, amplifier, sound amplifier

    An amplifier, also known as an Amplifier, is a device that takes the input signal from the Mixer and then enhances the sound amplitude to push out the speaker, also known as an amplifier. If the speaker system has a compatible built-in Amplifier, there is no need to use this device.

    ✔ Signal Processors: Processor, Crossover, Equalizer, Compressor

    Audio processing equipment such as: Crossover - Frequency crossover, Equalizer - Frequency filter, Compressor - Compressor signal, ... today are built into a device called Audio Processor. This device receives the signal from the Mixer to process it according to the intention of the installer, then transfers the signal to the power amplifier and output to the speaker. Today's digital mixers also often have these functions. So in the design process, experts will need to consider its necessity.

    ✔ Microphone set, Stage box, Connector Jack, speaker wire, signal wire, power divider

    These are small, must-have devices. We categorize the last because there are many necessary products, depending on each requirement, you can choose the quantity and they type accordingly.
