Commentary
An FM/AM digital synthesizer tuner that uses technology to improve sound quality.
In order to improve the RF intermodulation characteristics, the front-end section is enhanced, and a twin varicap and a unique balance hold capacitor system are adopted to ensure an excellent dynamic range.
We have also adopted IDMOS FET for RF element, direct-through MPX, pulse swallow method, and other technologies for improving sound quality.
Loop antennas and new ICs are used in the AM section.
AM/FM each 6-station preset is available.
