BK-7000G高速移频数字反馈抑制器
Adjustmentfrequencyshiftingdigitalfeedbacksuppressor
产品特性
⑨ 消除反馈于未然
{ \scriptsize { 1 } } 自动适应声学环境
{ \scriptsize { 1 } } 多达12dB附加增益,有效预防反馈发生
⑨ 4通道平衡的线路或话筒输入,提供幻象电源
⑨ 自适应性过滤器可以在“快速”模式和“精确”模式之间进行转换。
⑨ 快速模式适用于话筒位置经常变化的场合:精确模式适用于话筒位置固定的场合。自适应性过滤器能够以较慢的速度收敛,从而抑制更多的混响成分。
{ \scriptsize { 1 } } 在声学反馈发生之前,可以额外获得多达12dB的增益,具体取决于声学环境和所选的操作模式。
{ \scriptsize { 1 } } 内置了自动混合器,以实现4路话筒输入。许多情况下,如在演讲台、讲坛或会议桌上,采用4个话筒可以更好地捕捉正在移动中的演讲者的声音,而这样常常会增加声学反馈的风险。鉴于这一问题,反馈抑制器中的自动混合器将会自动降低信号输入较弱的那个话筒的增益,同时提高信号输入较强的另一个话筒的增益。
