选择立体声、并行或桥式模

放大器可被设置成一般立体声操 作、并行输入模式或桥接单声道模 式。

立体声模式 - 对内的两个通道是独 立的,可用于两个不同的信号。

并行模式 – 该设置将两个输入信 号连接在一起。一个信号输送到两 个声道。每个通道的增益控制和扬 声器连接都是独立的。

桥式 - 该设置将声对中的两个通道 结合为一个通道,使用两倍的输出 电压。只使用第一个声道的输入端 和增益控制。将第二声道的增益控 制设置为最小。此负载必须进行高 压 (或伏特)比率测定,然后按第 6 和第 7 页说明进行连接。

在并行模式和桥模式下连接输 入不要超过一个。

设置低频滤波器

ISA 280, ISA 450, ISA 750 和ISA 1350:推荐使用此低频过滤器。用 相应的开关设定关闭或打开过滤器 进行过滤器频率选择。设在开的位 置上,通道上每八位元有一个 12dB 低频过滤器,用于限制压音频锥形 运动,可使扩音器额定频率范围获 得更多电源。过滤器只可以在驱动 低音扩音器时关闭。

ISA 300Ti, ISA 500Ti, 和 ISA 800Ti:低频过滤器一直为活动状 态。每一通道都有一个 12dB/ 八位 元低频滤波器,防止 70 伏特 扬声 器转换器饱和。这会减少失真和防 止放大器超载。50 Hz 的设置通常 在高质量扬声器转换器中工作良 好。75 Hz 的设置在演讲级扬声器 和变压器中工作良好。
