With a jukebox connected to Source input 1, and the Talkover switch 2 on, the other Source input signals such as background music, will be muted and only the jukebox will be heard. FAULT PROTECTION The fault protection in the MA1705 limits the current to the output stage. This mode is entered whenever the output stage is called upon for too much power, it may also be fooled by impedances lower than four ohms - which may cause the output stage to overheat and be irreversably damaged.
