ABSTRACT:
A cue recording system for magnetic recorders responds to the closure of a pushbutton switch which is operated when a cue signal is to be recorded, by activating a duration decision circuit which maintains a cue generator in operation during a time duration determined by the decision circuit for magnetic recording thereof, independently from the length of time during which the pushbutton switch is held closed. With a magnetic recorder in which an acoustic signal to be recorded and a cue signal is recorded on one track of the magnetic tape, in serial fashion a short-circuiting or AGC transistor is rendered conductive as the cue generator is turned on, thereby short-circuiting or attenuating a record input from an associated microphone.
