Abstract: Apparatus is provided wherein signals which are reproduced from a record medium and which are supplied to head-phones are selectively attenuated and, concurrently, audio electrical signals produced by a microphone are superimposed onto these attenuated signals. An attenuator is coupled between a record/playback transducer and an amplifier; and a switch exhibits a first condition to short-circuit the attenuator, and a second condition to enable the attenuator to attenuate the signals reproduced by the record/playback transducer and also to superimpose the audio electrical signals produced by the microphone onto the attenuated signals. In one embodiment, a record/reproduce selector selectively establishes either a recording mode, whereby the audio electrical signals produced by the microphone are amplified and supplied to the record/playback transducer, or a reproducing mode, whereby the signals reproduced from the record medium by the record/playback transducer are supplied to the amplifier.

Abstract: Apparatus having a record/ reproduce selector is provided wherein signals which are reproduced from a record medium and which are supplied to head-phone jacks 4, 5; 9, 10 are selectively attenuated and, concurrently, audio electrical signals produced by a microphone 15, 15% are superimposed onto these attenuated signals. An attenuator 2, 7, 14, 14% is coupled between a record/playback transducer 1, 6 and an amplifier 3, 8; and a switch 12, 13 has a first condition to short-circuit the attenuator 2, 7, 14, 14% and a second condition to enable the attenuator 2, 7, 14, 14% to attenuate the signals reproduced by the record/ playback transducer 1, 6 and also to superimpose the audio electrical signals produced by the microphone 15, 15% onto the attenuated signals. In the recording mode, audio electrical signals produced by the microphone 15, 15% are amplified and supplied to the record/ playback transducer 1, 6.

Abstract: The electronic apparatus includes at least a receiver having synthesizer section for selecting a receiving frequency and providing an information signal corresponding to the selected receiving frequency, a micro-computer operating on a clock signal (fc) for controlling the synthesizer section, and a circuit responsive to the information signal for shifting the clock frequency when the selected receiving frequency is a frequency disturbed by a higher harmonic (Sh) of the clock frequency, thereby to avoid disturbance of reception of the broadcast signal without requiring undue reduction of the clock frequency.
