Commentary
FM/AM tuner equipped with auto IF.
Equipped with auto-IF to respond to changes in radio wave conditions.
This circuit automatically narrows the IF band to give priority to sensitivity when there are other broadcast radio waves near the receiving station or when there are strong interfering noise radio waves, and automatically switches the IF band to give priority to sound quality when there are no interfering waves.
In addition to the quartz of the tuning circuit and IF stage, the MPX circuit is also equipped with a twin quartz system. The operation accuracy is greatly improved and excellent separation characteristics are obtained. In addition, the DC configuration that enables wide-band playback is used to improve sound quality.
Equipped with an easy-to-use rotary tuning knob in addition to preset keys.
The amplifier section is equipped with a unique classAA circuit for more faithful signal transmission.
