Commentary
An FM/AM tuner that supports DC amplifiers by bringing together the latest circuit technology of the time.
A MOS-type FET is used for the high frequency stage, and in combination with a newly developed wide-gap precision frequency linear 4 series variable capacitor, high sensitivity and improved interference rejection capability are realized.
The FMIF part has a total of 10 stages by 5 differential ICs, and wide and narrow band selectivity switching is possible.
Uses 1.5 MHz, P-P wide range ratio detection circuit of low distortion rate design.
The MPX section focuses on high stability and sound quality by applying NF circuit technology to the buffer amplifier of IC for PLL.
Built-in test oscillator for recording.
Equipped with noise canceler switch.
Output level can be adjusted.
Equipped with FM muting switch.
