Commentary
This CD player was created by introducing the latest devices such as S1 type D/A converter and CDM-1MkII mechanism.
The D/A converter uses the S1 type TDA1541A-S1 with a crown mark, which is carefully selected from the latest A version. The CD-80 uses a 16-bit 4 x over-sampling digital filter to convert the signal into an analog signal using an L/R-independent S1 device. This eliminates harmful digital components such as 0 cross distortion.
The mechanism section is equipped with a CDM-1MkII mechanism that employs a robust die-cast frame and a long-life brushless Hall motor. In addition, the entire mechanism is made completely floating with dampers and springs to achieve excellent loading performance.
In addition, unlike normal linear tracking, it uses a swing arm system with weights placed at the rear, making it possible to read signals stably at all times.
Access time is further improved by adopting newly developed servo ICs for the servo circuit.
The main chassis is solid die-cast, the top is non-magnetic aluminum plate and the bottom is 3-mm-thick metal plate. Together with die-cast side panels, the Antivibrating Unified Frame (AUF) structure is unique.
It also uses a heavy-weight aluminum insulator.
A large transformer is used for the power supply and a separate structure is used to supply power to each of the servo system, analog system, digital system, and display independently to prevent mutual interference between circuits.
In addition, the Celafine type capacitor significantly reduces the impedance of the power supply. In addition, the circuit parts are strictly selected, including specially made ones, and the copper thickness of the signal path is doubled where necessary to improve sound quality.
Since a DC coupling configuration is adopted in the output stage and no capacitor is required to cut off the DC component, there is no signal degradation.
It is equipped with a unique FTS function that can program 126 discs semi-permanently (as a program of 5 songs per disc).
It is equipped with functions such as a 20-track program, five edit functions, random play, and AMS (Automatic Music Scan) that plays songs sequentially.
It has a dimmer function that can adjust the brightness of the display.
In addition to fixed and variable analog outputs, it is equipped with optical and coaxial digital outputs.
Equipped with a 35-key full remote control. Dimmer and AMS are remote-only functions.
Available in 2 color variations, gold and black.
