音声増巾回路。In a tape recorder with a radio, a recording/playback selector switch connected during recording is connected in series between the output terminal of a preamplifier/radio line amplification circuit 2 whose input terminal is connected to a radio/tape recorder selector switch 4 and a recording/playback head 10. 17
and a radio-tape recorder changeover switch 5 for connection to the radio, a radio recording current limiting resistor 13, and a resistor 12 between the output terminal of the preamplifier/radio line amplifying circuit 2 and the terminal 1 of the volume controller 11. The radio tape recorder selector switch 6 provided between this connection point and the ground connects the radio tape recorder selector switch 6 to ground the radio resistor 14, while the radio tape recorder selector switch 6 connects the C terminal of the resistor 14 to the volume controller 1.
A resistor 18 and a capacitor 19 are connected in series between the terminals 2 of the volume controller 11, and the recording/playback switch 8 short-circuits the resistor 18 and the capacitor 19 during recording.
A resistor 20 is provided between the recording and playback selector switch 8 and the ground to short-circuit the resistor 20 during playback, and the output terminal of the output amplification circuit 3 is connected to the radio-tape recorder selector switch 5 during recording and playback. When the selector switch 17 is connected for recording, the recording/playback head 10 is controlled by the teleco recording current limiting resistor 16.
An audio amplification circuit for a tape recorder with a radio, characterized in that it is connected to.
