产品功能特点优势：
功率与性能
1. 功率输出
- 额定功率为100W，能够提供足够的音量覆盖，适用于商场、工厂、学校等需要大范围声音传播的场所。
- 支持70V/110V定压输入，确保在长距离传输过程中信号的稳定性，减少功率损耗，保证声音质量。
2. 频率响应
- 频率响应范围为300 - 10000Hz，能够清晰地还原人声和大部分音乐的频率，使声音听起来自然、清晰。
- 灵敏度达到110dB，这意味着在输入较小功率时就能产生较大的声压级，具有较高的声音转换效率，节省能源。
声音传播特性
1. 定向传播
- 作为定向号角，能够将声音集中向特定方向传播，减少声音在非目标区域的扩散，避免声音干扰，适用于需要定向广播的场所，如车站、码头等。
2. 声音覆盖范围
- 广播覆盖半径可达100m，能够满足大面积场所的声音覆盖需求，无论是户外广场还是大型室内空间，都能实现有效的声音传播。
安装与使用
1. 安装便捷性
- 设计有便于安装的结构，可通过支架或其他安装方式固定在不同位置，安装过程简单快捷，节省安装时间和成本。
2. 操作简单
- 定压输入的方式使得设备在连接和操作上较为简单，不需要复杂的调试过程，易于使用和维护。
Product Features Advantages:
I. Power and Performance
1. Power Output
- The rated power is 100W, which can provide enough volume coverage, suitable for shopping malls, factories, schools and other places that require a wide range of sound transmission.
- Support 70V/110V fixed voltage input, to ensure the stability of the signal during long-distance transmission, reduce power loss and ensure sound quality.
2. Frequency Response
- Frequency response ranges from 300 - 10000Hz, which can clearly restore the frequency of human voice and most of music, making the sound sound sound natural and clear.
- Sensitivity of 110dB, which means that in the input of a smaller power can produce a larger sound pressure level, with a high sound conversion efficiency, saving energy.
1. Directional propagation
- As a directional horn, it can focus the sound propagation in a specific direction, reduce the spread of sound in non-target area and avoid sound interference, which is suitable for places that need directional broadcasting, such as stations, docks and so on.
2. Sound coverage
- Broadcast coverage radius up to 100m, can meet the sound coverage needs of large places, whether outdoor plaza or large indoor space, can realize effective sound transmission.
Installation and Use
1. Installation Convenience
- Designed with an easy-to-install structure, it can be fixed in different positions by means of brackets or other mounting methods, which makes the installation process simple and quick and saves installation time and cost.
2. Simple operation
- Constant pressure input method makes the equipment simpler in connection and operation, no need for complex debugging process, easy to use and maintain.
