✔ Sound system needs to permeate the whole tea room and music stage

The project manager needs to know the area of the music stage used, how many people to design the sound accordingly. This will help the project manager to calculate the number and type of equipment for the whole room. As a result, sound can be spread out throughout the room.

In addition to the area factor, it is necessary to consider the height of the musical stage. In the case of high-ceilinged music stages, the design becomes simple. But with celling of less than 4m, hanging large-capacity speakers will not be suitable. The best method for low-ceiling music stages is to use speakers with sufficient power and even range of speakers to be able to spread sound throughout the room.

✔ Use compatible devices, compact system design

The audio equipment included in the design should choose the latest equipment which is simple, easy to operate, easy to maintain, and capable of updating new technologies. It is not recommended to use too many devices with duplicate functions. It is recommended to integrate systems so that it is compact, easy to transfer technology.

Investors often have a nervous and anxious mentality when spending money investing in an audio-visual system. Because sound is a product that cannot be measured immediately, its effectiveness will usually give results after a process of use. Most investors often choose partners to cooperate with to avoid risks. However, for those who have never carried out similar projects or lack information about audio and lighting equipment suppliers, choosing a supplier is not simple. The following will be shared with you for more information.

✔ Buy genuine equipment, of clear origin with CO, CQ

In case the initial budget is not much, you can buy softer priced products from not too famous companies in the market. You should not buy counterfeit goods. Current sound equipment is quite diverse in types, prices, and quality of genuine companies including Chinese goods. If it is genuine, it is still good. The purchase of counterfeit products will only be economical but mainly counterfeit goods are produced in Vietnam with poor quality. Units using counterfeit goods are also often not very reputable units.

CO, CQ is a certificate of quality, the origin of goods that are genuinely provided to the importer by the customs departments of the local country.

✔ Select reputable and experienced units in the market

Reputable and experienced units in the market will be very careful when performing a job that can affect their reputation. It is advisable to refer to the price from these units in advance to get the most reasonable design. Then will refer to the same units to choose a well-priced unit with similar equipment.
