SA 系列专业功率放大器:

   

 
  无以置疑,工放在整各扩音系统中的重要作用,好的功放可以将音箱发挥得淋漓尽致。SA系列是SOUNDLTER功放系列的核心产品,它具有如此众多的优点:
* 2u安装高度设计;
* 高强度的钢板机壳
* 独特的散热系统构成与机内空间完全隔离密封通道,* 让冷却气流从中流过,避免了由于外界污染对机器造成的损害, 并使其具有良好的散热效果;
* CLASS H 逻辑电源开关线路,提高整个电源线路的工作效率,在狭小的机箱内蕴涵着庞大的功率;
* 另外还有它独具匠心的保护线路。

  SOUNDLITER功放系列是特意为专业买家而打造的产品。我们专们设计了特有的保护线路“SOA”:当散热器的工作温度升到摄氏60度时,风扇的转速达到最快,当工作温度达到摄氏80度时,“SOA”自动发挥作用,压缩输入信号,减少功放的功率电流,避免功放过热关机。

  为了方便安装和流动演出的需要。输出可以选择接线柱或Neutrik四芯接头,输入可以选择立体声、桥接、并连三种形式,简化了安装步,使用大型演出时显得更加方便。

  市面上充斥着很多滥竽充数的功放产品。一些功放可能披着漂亮的外表和极低的价格,但只要你听其声音,便会发现它们的性能却不值一提,SOUNDLITER产品从来都注重质量和价格的平衡。高质量的元件和坚实的工艺打造出SOUNDLITER的核心产品:超群出众的SA系列功放!

 SB系列专业功率放大器
 

 
  SB系列功放是提供给用户更多选择的一个系列:3U标准安装高度;解决传统功放在工作期间出现停机现象的问题;充分提高输出电路的效率;富有力度的音色和可靠性能,以及高性价比。

  SB系列具有独特的散热结构及使用温控变速冷却风扇与机内空间完全隔离密封通道让冷却气流从中流过,避免了由于外界污染对机器造成的损害;设有压限控制及自动功能,避免高峰信号削波失真、音质变坏、烧毁高音喇叭等问题。配合由温度控制的冷却风扇,使整机的工作温度十分低,即使长时间满功率输出也绝无问题。

  SB系列功放的输出阻尼特性相当不错,推动低阻负载完全可以腾任;大功率的变压器内部设有过热保护开关;开机时有软启动功能,防止开机电流冲击;完善的保护功能:输出过载,直流输出,机器过热等等。功率放大器设置三种工作状态:双声道、并联、桥接;专业的输入输出端子,可以满足用户配接不同设备的需要,SPEAKON上并接了香蕉插头(可接裸线)提高系统的可靠性和适用性。
