摘要： PROBLEM TO BE SOLVED: To prevent a volume of sounds outputted from a television or audio apparatus from being increased more than needed by an erroneous operation when setting the sound volume of the apparatus.
SOLUTION: In an apparatus including a voice output, the range of a voice output level for ordinary use is set and when performing a setting change operation to the sound volume exceeding the set range of the voice output level, it is required to confirm whether or not the sound volume setting change operation is suited. Only when a response is obtained within a predetermined time, the sound volume setting is changed.

摘要： PURPOSE: To remove a click noise by providing a second C-MOS switch in a circuit device for adjusting the level of an audio signal by using a C-MOS switch. CONSTITUTION: A second C-MOS circuit IC2 is connected with a C-MOS circuit IC1 in parallel, and input sides e2.1-e2.8 of the IC2 are connected with a resistance chain RK2. An output signal extracted from an output side O1 of an arithmetic amplifier OP1 is transmitted through an inversion stage INV and a coupling capacitor CK3 to an input side e2.1 of the C-MOS switch IC2, and the signal is transmitted from an output side a2 through a coupling capacitor CK4 to the input side of an arithmetic amplifier OP3. The control input side of the C-MOS switch IC2 is connected with control input sides A, B, and C of the C-MOS switch IC1 in parallel, and an output OP of the arithmetic amplifier OP2 and an output side O3 of the arithmetic amplifier OP3 are connected with each input side of a differential amplifier OP4, and a valid signal Ua from which failure is removed is extracted from an output side O4.

摘要： PURPOSE:To fix the gain of the whole circuit by connecting a means for compensating the attenuation of an input signal to the output side of an amplifier. CONSTITUTION:A volume VR2 is connected to the input side of the amplifier and a volume VR3 is connected to the output side. The volume VR3 compensates the attenuation of an input signal by the volume VR2 and interlocks with the volume VR2 so that the variation of a resistance value is reversed against the volume VR2. Since the attenuation due to the volume VR2 is compensated by the volume VR3, the gain of the whole circuit is held at a constant level.
