Information

Technical index

The sound reinforcement characteristic index of the hall shall be carried out in accordance with the requirements of the national first-level characteristic index. details as follows:

Level 1 characteristic index requirements:

Maximum sound pressure level: greater than or equal to 110dB;

Transmission frequency characteristics: the average sound pressure level of 100~6300Hz is 0dB, within this range +/- 4dB is allowed, and 50Hz-10000Hz is allowed

Xu +4~-8dB;

Sound transmission gain: -8dB, 125Hz~4000Hz;

Sound field unevenness: less than or equal to 8dB, 1000~4000Hz;

Total noise level: less than or equal to 30dB (A).


Power requirements

In order to ensure the high-quality operation of the sound system, the following requirements are put forward for the power supply of the sound reinforcement system:

⑴. The power supply of the sound reinforcement system should be separated from the power supply of the lighting and the power supply should be handled by the voltage regulator equipment.

⑵. The transformer group of the power supply of the sound reinforcement system should be separated from the transformer group of the high-current power supply such as lighting and air-conditioning.

⑶. The power supply capacity of the sound reinforcement system is AC 220V/10 kVA. If conditions permit, it is best to use two-way power supply, with automatic switching between main and standby.

⑷. The power pipeline and the audio pipeline should be avoided as far as possible. If it is impossible to overcome, the interval should not be less than 50cm.

In summary, when designing your stage equipment project and selecting products, our company will always use rigorous and professional means and recognition

A truly responsible attitude designs scientific, reasonable, economical and practical solutions for your organization. At the same time, I also hope that you can offer us valuable
