公开了一种用于检测驱动卷到卷磁带传输系统的卷取线轴电机的宽带功率放大器中的故障的检测装置。反馈回路从放大器的输出端连接到位于放大器输入端的故障结。监测故障接点的信号，并将其与预定范围内的标准参考信号进行比较。每当故障结信号超出预定范围时，功率放大器就关闭，从而防止损坏磁带。放置滤波装置以便使比较装置脱敏，直到放大器工作在稳定状态。
A detection device for sensing malfunctions in a wide band power amplifier, driving the take-up spool motor of a reel-to-reel tape transport system, is disclosed. A feedback loop is connected from the output of the amplifier to a malfunction junction positioned at the input of the amplifier. The signal at the malfunction junction is monitored and compared with a predetermined range of standard reference signals. Whenever the malfunction junction signal is out of the predetermined range, the power amplifier is turned off thereby preventing damage to the tape. A filter means is positioned so as to desensitize the compare means until the amplifier is operating at steady state.
