Commentary
A CD player equipped with two digital outputs, optical and coaxial.
A newly developed high rigid lock mechanism is adopted for the mechanism part.
In this mechanism, the optical pickup base and assembly base are independent, and a vibration isolation structure combining a special rubber damper and a coil spring is adopted.
Bi-pressed steel plates and high-rigidity materials reduce vibration, which is the cause of sound quality degradation.
An FCS (Fourtimes Current Superios) converter is used for the D/A converter.
This circuit uses the latest ladder network type D/A converter, and combines a 4 x oversampling digital filter and a super linear LPF with excellent phase characteristics.
In the power supply section, the analog and digital sections are supplied independently from the secondary winding of the power transformer, and each circuit is buffered by a stabilizing circuit to eliminate mutual interference between analog and digital circuits.
In addition, a line filter for eliminating pulsed noise is inserted into the power line to prevent errors in the microcomputer function.
Equipped with a system remote control terminal I/O, it can be operated with an F-105 remote control by combining it with an AV surround controller (F-105) sold separately.
Two analog outputs, front and rear, are installed.
The front output is a variable output linked to the headphone level.
The digital output terminal is equipped with two systems, coaxial and optical, for greater versatility. When the digital output is not required, it can be turned ON/OFF to cut unwanted radiation when the digital output is turned ON.
It is equipped with functions such as 16-track program memory function, memory check, music scan play, 4-mode repeat play, index search and single play.
Wireless remote control is included.
Side panels were sold separately.
