SP4400
*2U外观设计,四通道纯后级音频功率放大器输入有平衡、非平衡两种方式,立体声/单声道/桥接三种不同工作模式。
*独特的功率输出电路使用电压的动态范围更大,谐波失真及互调失真更小,
并使功率输出的晶体管工作在安全的区域,大大提高了可靠性。
*具有可靠的开机延迟,过载、过温、短路、零飘等多重保护,
*采用大容量滤波电容,优质环形低漏磁高值片变压器和高品质音频大功率输出管。
*重量轻使得运输和组装都非常容易,专门设计的底盘,可提供额外的耐用性和强度。
*由于每个通道都采用Neutrik speakon输出插口和1/4英寸输出插口,再加上
4路接线柱,可提供杰出的连接灵活性。
*功率管直贴散热器,大功率自动调节双速风扇有效降低机内温度,提高系统可靠性。
*所提供的综合保护措施包括电源开/关静音、Dc检测、热保护、电流/限制
和衰减器保护罩。
*2U appearance design
* Possess the multiple protection in boot-strap delay, overloading, superheat, short-circuit etc.
* Possess the multiple protection in boot-strap delay, overloading, superheat, short-circuit etc.
* Adopt big capability filter capacitance, excellent circular transformer of high-value chip and low magnetic field leakage, high-power and high-quality big power output tube.
* The light weight make the shipping and load more easy, proessional batholith can offfer the extra strength and durable usage.
* Each channel adopts Neutrik speakeon output interfac and 1/4 inch output interface, and 4-way post head, which can meet various connection types.
* The power pipe affixed to the radiator, the double-speed and high-power fan could automatically regulate and reduce the inner temperature and enhance the reliability of the system.
* The integrated protective measures including: power on / off, mute, Dc detection, thermal protection, current / limition and attenuator shield.
