Commentary
A slim design FM/AM stereo receiver with an emphasis on usability and smartness.
The amplifier section uses a power amplifier block of Low-TIM design with DC amplifier configuration.
In the tuner section, a dual gate MOS FET with excellent noise removal performance is mounted on the front end to obtain excellent reception performance.
In addition, it is equipped with a tuning guide using LED and a pilot canceler that make it easy to find the optimum tuning point.
It is equipped with functions such as loudness and high filter, microphone mixing circuit, FM muting switch and LED indicator.
