Nakamichi DVD-15
135,000yen(2000 release)

The 5 disk DVD changer which carries a music bank system original with a Nakamichi, sets DVD and compact disk freely, and can perform a succession performance of the disk of five sheets etc.

The music bank system is carried in the changer mechanism.
In this system, a large-sized tray or magazine are not used but can perform an attachment and a switching of a disk like the usual DVD player. Moreover, in order to hold and convey only the edge part of a disk, a music signal part is not touched at all.

Dolby digital and a digital-termination-service decoder are carried, and the 5.1ch analog output terminal is carried.
Furthermore, various setupses of a front speaker, a center speaker, a surround speaker, and a subWoofer and the delay time of each speaker of a center and surround can be adjusted.

Two digitized voice outputs are carried.

The sampling /24bit, and the linear digital analog converter for audios corresponding to a PCM format of 96kHz which are the highest specification of a DVD format are carried.

Moreover, change into 10 bits the picture image data of DVD currently recorded by an eight-bit / 13.5MHz, a sampling frequency is made to step up to an image system to 27MHz, and the 10-bit video-system digital analog converter is carried in it.

The 2 waves of CD-Recordable correspondences twin Focus pickup is carried.
Since the media to reproduce is selected automatically and the optimal laser power is outputted, the outstanding reading performance has been realized.

The component (color difference data) image output is carried, the D-A conversion of the component picture image data (Y, CB, CR) recorded on DVD can be carried out direct, and it can be outputted.

The headphone jack in which a loudness-level-of-sound coordination is possible is carried.

Wireless remote control is attached.
