Commentary
An FM/AM stereo tuner amplifier that integrates an amplifier and a quartz synthesizer tuner.
The tuner section uses a quartz synthesizer system for channel selection and tuning to achieve accurate tuning accuracy.
It is also equipped with functions such as preset tuning for 6 FM/AM stations and last one memory.
It is equipped with a battery backup function to protect the contents of memory, so that memory does not disappear due to power on/off or unexpected power failure.
In addition to the digital display of the receiving frequency, 16 LEDs in a horizontal row light up one after another in accordance with the receiving frequency. You can enjoy the feeling of an analog tuner.
A high-performance low-noise IC is used for the equalizer circuit of the amplifier for each channel independently.
The main amplifier circuit is composed of a main amplifier section with less distortion by adopting a hybrid IC that compactly accommodates two channels on the left and right.
The power transformer of the power supply circuit uses a special XCO compound floating structure which is excellent in heat radiation effect and absorbs internal vibration well, and is stored in a double shield case to suppress harmful magnetic radiation.
