Commentary
An FM/AM tuner equipped with a band switching function in order to enjoy AM stereo with higher sound quality.
The wide / Narrow Position function, which can be switched according to the reception condition, is installed in order to receive higher quality sound.
When the reception condition is good, setting the Wide position to give priority to the sound quality greatly improves the frequency characteristics.
In addition, when the input power is weak or when the noise radio wave is strong, the Narrow position, which gives priority to the selectivity, makes the reception easier to hear.
It is equipped with 4-row front end module developed in-house. Twin varicap is used for tuning element and MOS FET is used for RF amplifier to suppress intermodulation interference.
In addition, it is equipped with an RF attenuator that suppresses distortion at strong input, and the IF stage is composed of three stages to suppress interference from adjacent stations.
Equipped with FM/AM random 36 station preset function.
Use the tuning button to adjust the frequency of the broadcasting station you want to preset, press the memory button, and then set any button while the display is flashing to complete the preset.
It uses a honeycomb insulator with excellent vibration absorption from the outside.
In addition, we have adopted components such as acoustic condensers and resistors that were selected through repeated hearings.
It is equipped with a mode memory that can store stereo / mono ON/OFF.
It also has an RF attenuator that is effective for strong input, and an SR terminal that enables linkage with Pioneer systems.
