You can also adjust the front, center, surround, and subwoofer settings, as well as the delay time of the center and surround speakers.

Equipped with two digital audio outputs.

Equipped with an audio D/A converter that supports 96 kHz sampling / 24-bit linear PCM format, the highest standard of DVD format.
The video system is equipped with a 10-bit video D/A converter that converts DVD video data recorded at 8-bit / 13.5 MHz into 10-bit data, and steps up the sampling frequency to 27 MHz.

Equipped with CD-R-compatible 2-wavelength twin focus pickup.
Excellent read performance is achieved by automatically selecting the media to be played and outputting the optimum laser power.

Equipped with component (color difference data) video output, component video data (Y, CB, CR) recorded on DVD can be directly D/A converted and output.

Equipped with a headphone jack with adjustable volume level.

Wireless remote control is included.
