Connect the line to handle good when connect the line can t is firm the power cable and signal line together , can affect the signal because of the alternate current . the signal line or trumpet line can t all tie knot , and would otherwise affect the tone color . signal line or trumpet line over long want to change short . many signal line all contain direction , and don t get mistake 接线处理要得当接线时不可把电源线与信号线扎在一起，因交流电会影响信号。信号线或喇叭线均不能打结，否则会影响音色。信号线或喇叭线过长要改短。
