产品优势：
灵活的阻抗定制
在音频设备的连接中，阻抗匹配至关重要。FK - 300充分考虑到这一点，其额定阻抗可定制为8Ω。这种灵活性使得它能够与各种不同的功放设备完美适配，无论是现有的广播系统升级，还是全新系统的搭建，FK - 300都能轻松融入其中，确保音频信号在传输过程中的高效性和稳定性，最大限度地减少信号损失和失真。
出色的声学性能
1. 宽频响应
- FK - 300的频率响应范围为300 - 10000Hz，这一宽广的频率范围能够确保声音的还原度极高。无论是低沉的低音，还是清脆的高音，都能被准确地重现，使得广播内容在音色和音质上都能达到最佳效果。
2. 高灵敏度与大声压级
- 该设备具有110dB±3的高灵敏度和130dB±3的最大声压级。高灵敏度意味着它能够在较低的功率输入下产生足够响亮的声音，这不仅节省了能源，还延长了设备的使用寿命。而较大的最大声压级则保证了在各种复杂环境下，声音都能够清晰可闻，不受外界噪音的干扰。
精准的定向广播功能
FK - 300的波束宽度为360°×30°（@2.5KHz/ - 6dB），这种独特的定向广播特性使其能够将声音集中在特定方向进行传播。在实际应用中，这意味着广播者可以将声音准确地投向目标区域，避免对其他非目标区域造成不必要的噪音干扰。例如，在机场、车站等人员密集且区域划分明确的场所，定向广播功能可以确保航班信息、列车时刻等重要通知准确地传达到旅客耳中，同时不会对周边工作人员或其他旅客造成困扰。
高语言清晰度
在广播设备中，语言清晰度是衡量设备性能的关键指标之一。FK - 300的语言清晰度（STIPA）达到0.8，这一高水准确保了语音信息能够清晰、准确地传达给听众。无论是紧急广播、公共通知，还是商业宣传，听众都能够轻松地理解广播内容，避免因声音模糊不清而导致的信息误解或遗漏，从而保障了广播的有效性和实用性。
坚固耐用的设计
1. 物理防护
- FK - 300在设计上充分考虑了不同环境下的使用需求。其防风等级达到≥12级，能够在恶劣的天气条件下正常工作，如强风肆虐的沿海地区或风力较大的高山场地。同时，外壳防护等级为IP56，这意味着它能够有效抵御灰尘和强烈的水流冲击，无论是在尘土飞扬的矿山，还是在潮湿多雨的户外环境，都能保持良好的工作状态。
2. 合理的尺寸与重量
- 设备的尺寸为490×480×260(mm)，净重23kg，这种设计在保证了设备性能的同时，也兼顾了安装和搬运的便利性。它既不会因为体积过大而难以安装，也不会因为重量过轻而影响其在强风环境下的稳定性。
Product Advantage:
Flexible Impedance Customization
Impedance matching is crucial in the connection of audio equipment. The FK - 300 takes this into full consideration, with a customizable rated impedance of 8Ω. This flexibility allows it to be perfectly adapted to a wide range of different amplifier equipment. Whether it's upgrading an existing broadcasting system or building a brand-new one, the FK - 300 can be easily integrated into it to ensure that audio signals in the transmission process are The FK-300 can be easily integrated into any existing broadcasting system, whether it is an upgrade or a new system, ensuring high efficiency and stability of the audio signal in the transmission process and minimizing signal loss and distortion.
Outstanding Acoustic Performance
1. Wide Frequency Response
- The FK-300 has a frequency response of 300 - 10,000 Hz, a wide frequency range that ensures a high degree of sound reproduction. Both low bass and crisp treble can be accurately reproduced, allowing broadcast content to be optimized in terms of timbre and sound quality.
2. High sensitivity and large sound pressure level
- The unit has a high sensitivity of 110dB±3 and a maximum sound pressure level of 130dB±3. High sensitivity means that it can produce loud enough sound at low power inputs, which not only saves energy, but also extends the life of the unit. The large maximum sound pressure level ensures that the sound is clearly audible in a variety of complex environments, without interference from external noise.
Precise directional broadcasting
The FK - 300 has a beamwidth of 360° x 30° (@ 2.5KHz/ - 6dB), a unique directional broadcasting feature that enables it to focus sound in a specific direction. In practice, this means that broadcasters can direct sound to exactly the target area, avoiding unwanted noise interference to other non-targeted areas. For example, in airports, stations and other densely populated places with a clear division of the area, the directional broadcasting function can ensure that important notices such as flight information and train schedules are accurately conveyed to the ears of travelers, while not disturbing the surrounding staff or other travelers.
High Speech Clarity
In broadcasting equipment, speech clarity is one of the key indicators of performance. The FK-300 has a speech intelligibility (STIPA) of 0.8, a high level that ensures that voice messages are clearly and accurately conveyed to the listener. Whether it's an emergency broadcast, a public announcement, or a commercial promotion, listeners can easily understand the content of the broadcast, avoiding any misunderstanding or omission of information due to muffled voices, thus guaranteeing the effectiveness and usefulness of the broadcast.
Ruggedized Design
1. Physical Protection
- The FK-300 is designed with the needs of different environments in mind. Its windproof rating reaches ≥12, enabling it to work normally in harsh weather conditions, such as coastal areas ravaged by strong winds or alpine sites with high winds. Meanwhile, the enclosure protection level is IP56, which means it can effectively resist dust and strong water impact, whether in dusty mines or wet and rainy outdoor environments.
2. Reasonable size and weight
- The size of the equipment is 490×480×260(mm) and the net weight is 23kg. This design ensures the performance of the equipment and also takes into account the convenience of installation and transportation. It is neither too large to be difficult to install nor too light to affect its stability in strong wind environments.
