る。The recording amplifier circuit AMP1 has a terminal 01 for inputting a guidance message and a terminal A1 for inputting a voice message.
The gain can be controlled. The input of the AGO circuit is connected to terminal 1, that is, the input level of the voice message, and its output is connected to the recording amplifier circuit A M P L
is connected to the gain control terminal of the AGO circuit is terminal C
The input/output characteristics are adjusted according to the input level from 2 onwards.

るように制御する。The average voice level Io of the guidance message is given to the terminal C2, and when the level Is of the voice message from the subscriber is input to the terminal AI, the gain of the recording amplifier circuit is changed by the output of the AGO circuit to the average of the voice message level and the guidance message. Adjustments are made to reduce the audio level difference. For example, when a voice message of l5=Io is input, AG
The O circuit does not operate, and the gain of the recording amplifier circuit AMPs remains unchanged. Also, the level of the voice message is I
When s = "/2 IG, the AGO circuit controls the gain of the recording amplifier circuit AMP+ so that it is twice the gain when l5 = IG.
