ALPINE/LUXMAN D-115

Commentary

A CD player equipped with a coaxial digital out terminal for digital output.

Equipped with a high rigid lock mechanism in which the optical pickup base and the base of the whole mechanism are independently designed. It is an anti-vibration mechanism combining a special rubber damper and coil spring.
In addition, bi-breath steel plates and high-rigidity materials are used to suppress unwanted vibrations.

A line filter is inserted in the power supply line to remove pulse noise to prevent malfunction of the microcomputer function.
The secondary windings of the power transformer are independent and buffered by a stabilizing circuit to prevent interference between the digital and analog circuits through the power supply.

The D/A converter uses a ladder network type D/A converter, and the digital filter uses a double oversampling digital filter.
The S. T. A. R. circuit is mounted on the analog circuit after D/A conversion.

Equipped with system remote control input / output, and in combination with separately sold AV surround controller (F-105), ALPINE/LUXMAN components can be controlled by the F-105 remote control.

16-track program memory, memory check, music scan play, 4-mode repeat music scan play, 4-mode repeat play, index search, and single play.

A remote control (RD-109) was included.
