产品特点/Features
     
XA系列功放采用独特的全对称浮地设计,这样的优点是功放的失真能相互抵消,这样使失真更小,声音更准确,缺点是制造成本更高一些。
具有电源自动转换系统,在小功率时,电源并联工作,使输出电流能力提高,输出阻抗更低。在大功率时,电压自动升高,使输出功率更大。
有输入电源滤波器,抗干扰能力更强。
放大电路外加屏蔽罩,变压器增加屏蔽环,这样使噪音更小,声音更干净。
独立封蔽风道冷却,使散热更快,即使长时间使用也很干净。
具有完善的保护功能,开机缓冲,延时接通扬声器,还有限幅功能,过电流保护,过热保护,短路保护,输出直流保护等功能。
XA series amplifiers adopt unique full symmetrical float to design,this has the advantage of amplifier distortion can offset each other,this makes less distortion,sound more accurate,the disadvantage is that the manufacturing cost is higher.
the automatic power conversion system,in the small power,the power supply in parallel work,make the output current capability,more low output impedance.At high power,automatic voltage increases,the output power is bigger.
with input power supply filter,stronger anti-interference ability.
plus a shield,amplification circuit,increase shielding ring transformer,so that make less noise,sound cleaner.
independent sealing cap wind cooling,heat faster,even if long time use is also very clean.
have perfect protection function,boot buffer,delay on speaker,also limited functionality,over-current protection,overheating,short circuit protection,output dc protection,and other functions.
