*2U外观设计，四通道纯后级音频功率放大器输入有平衡、非平衡两种方式立声体/单声道/桥接三种不同工作模式
*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, the input is balanced, non balanced two kinds of ways to make a sound body / mono / bridge three different working modes
* has reliable power on the delay, overload, over temperature, short circuit, zero drift and other multiple protection
* the use of large capacity filter capacitor, high quality annular low leakage magnetic high value piece of transformer and high quality audio power output tube.
* light weight makes it easy to transport and assemble, specially designed chassis, which can provide additional durability and strength
* the Neutrik speakon output socket and 1 / 4 inch output socket is adopted in each channel, and 4 on the road terminal, provide outstanding connection flexibility.
* power tube heat sink, high power automatically adjust two speed fan to effectively reduce the internal temperature of the machine to improve the reliability of the system
