Commentary
FM/AM tuner with enhanced basic performance.
By installing a linear switching MPX / IC, the switching section is greatly simplified, and the linearity is improved by constructing a dynamic switching section without nonlinear elements, thereby eliminating the sound quality degradation caused by nonlinear distortion and phase shift.
A classAA circuit is mounted in the post-amplifier section, and voltage amplification in an ideal A-class state is realized by installing a special current drive amplifier, thereby eliminating adverse effects from the connected cord and amplifier.
The DC configuration of the amplifier circuit, detector circuit, and stereo demodulation circuit realizes more faithful waveform transmission.
Equipped with an auto-IF circuit, the microcomputer automatically switches between two circuits, a normal circuit that gives the highest priority to sound quality and a super narrow circuit that is resistant to adjacent station interference, so that optimum reception is always possible.
Equipped with a signal fidelity indicator.
When this indicator lights up, high-quality air check is possible.
Equipped with signal strength lead-out, it can digitally display the input signal strength of the receiving station.
It is equipped with a random preset function for a total of 16 FM/AM stations.
Equipped with auto-scan tuning and auto-memory function.
