Sound Lighting Systems

What equipment does the stage sound and light include?

The sound and light system of the hall will be a combination of the hall sound system & stage lighting system together to serve certain purposes. Called a synchronous light and sound system. These devices are combined and controlled by an operator or a computer software to create a complete and optimal lighting and sound system. In there:

Hall sound system - event stage

Also known as Audio System includes many different devices, depending on the purpose of use and the size of the system. Here are some basic equipment in an audio system:

1. Speaker (Speaker): is a device that converts electrical signals into sound waves, produces sound and emits it into the surrounding space.

2. Amplifier: is a device that enhances the audio signal to bring that signal to the speaker with stronger intensity, making the sound clearer and more vivid.

3. Mixer console: is a device that allows users to adjust and combine audio signals from many different sources to create a common audio signal.

When it comes to the design and installation of sound and lighting systems for the hall , music stage, people often think of a very professional sound system. With 10 years of experience working deeply in the field of sound, light and art. We - Hoang Sa Viet Sound and Light Company would like to share the following points to note for your reference before choosing audio equipment suppliers.

Notes when designing sound and lighting for the stage hall

Having worked in this field for many years. We understand that the most important thing whether a sound system, light, music stage is effective or not is still the design stage. System design does not mean bringing together expensive products to produce good results. The essence of the design of a sound and light system is to solve the logical problem for the following 4 factors:

• Use equipment according to the function of each professional system, for example:
• Performance sound, meeting room sound, cinema room sound...
• The device works well at that space and environment at that stage
• Simple operation, maintenance and maintenance, easy technology transfer.
• The investment cost for the system is suitable, cheap, quick to recover capital and avoid waste.

When designing sound and lighting systems , stages, halls, concerts and events, it is necessary to meet the above 4 factors, the system will achieve the highest investment efficiency. Therefore, it shows the importance in the design of the stage and hall sound system that it is very important to have reasonable solutions for each project and work to ensure efficiency and minimize problems. Inefficient investment.

Design the correct stage sound system for the hall

The hall stage sound system is actually not that simple, because the hall stages require a higher level of sound and light quality. The current hall stage is often very versatile. The function of a company or office hall is not just for meetings and presentations. It is also a professional performance stage, used for performing arts. Company activities for workers, management and other business activities...Halls with poor sound quality will immediately affect the operation of the agency and business. Karma. Therefore, the system design work needs to be done professionally. For effective investment, standard design, please note the following points:

1. Identify the main use of the hall: You need to determine what the purpose of the hall is to regularly use the sound system for. Accordingly, focus deeply on those needs to design a sound system that serves the most frequent needs. For example, a hall sound system that mainly serves meetings will be different from a sound system that mainly serves cultural performances. The difference is as follows: The conference hall sound system will not need too much power, the audio equipment is small but evenly distributed, does not create great pressure for listeners and is suitable for meeting and no Sub speaker (subwoofer). In the opposite direction, the hall sound system that mainly serves music will have a larger capacity, arrange many large speakers and many Sub speakers (more subwoofer).

2. Speaker system layout design: Speaker systems need to be placed in suitable positions to ensure uniform sound distribution in the hall. If the hall has a complex shape, it is recommended to use multiple speakers to ensure uniform sound across the entire area.

3. Choosing the right speakers and equipment: You need to choose the right speakers and audio equipment for the needs of the hall or meeting room. Factors such as power, sensitivity, frequency and sound range need to be considered to ensure that the sound is delivered correctly and sufficiently to cover the space.

4. Sound chain system design: The sound chain system needs to be designed so that the connection between devices is made correctly and stably. Factors such as line length and number of devices connected need to be considered to ensure sound is not degraded or interfered with.

5. Use compatible and synchronized devices: Audio devices included in the design should choose the latest, simple, easy to operate, 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.

✔ Interior design enhances sound dispersion, sound absorption reduces echo

This is important for a tea room, music stage with standard sound quality. 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 music stage.
