·该系列机型的保护电路不只停留在对扬声器的直流保护上面,更重要的是让它适应恶劣的工作环境,而能轻松工作;

·该系列功放具有极好的信号转换特性,它具有非常小的谐波失真(THD),互调失真(SMPTE-IM),瞬态互调失真。纯真、自然的音质演绎了至真完美的音乐;

·开机延时,关机哑音防冲击保护,保护扬声器不会受到强烈的冲击电流而发生噪音;

·该系列功放率放大器运行稳定可靠,使用与长时间的工作环境,高效的通风结构确保了产品的可靠性和安全性,是剧院、俱乐部、游乐园、巡回演出首选的功放;

·该系列功放从超低音到*细腻的高音区能提供清澈明亮和饱满有没得音质,对扬声器系统的控制更是挥洒自如;

·高电流唤醒变压器,大容量滤波电容,在热河情况下,始终给您提供宽裕的余量,使功放的输出功率更强,推动力更大。极低噪声设计,提供更有没出色的音质;

·平衡XLR输入接口,可切换的立体声,并联及单声道桥接操作模式,两段灵敏度选择开关供客户选择不同的输入电平,专业SPEAKON输出插座在加上接线柱,使连接更具备灵活性;

·该系列的短路保护功能,它能保证工程人员在误操作或其他意外的情况下,保护机器本身及扬声器安全可靠地工作。
