JVC Ex-D1 is a DVD Audio/Video playback, two-channel Dolby Digital/DTS decoding system.
The solid wood cones featured in the new EX-D1 provide an ideal combination of high sound propagation speed and sufficient internal loss, allowing the speakers to naturally reproduce a wide frequency range. With conventional paper cones, sound spreads at the same speed in all directions, causing unnatural resonant points with limited frequency response. Wood cones produce few resonant points because of the grain, so frequency response is improved and sound quality is significantly enhanced. JVC engineers tried several types of wood, but birch proved to have the best acoustic properties.
The speakers are encased in a solid cherry-wood enclosure for superior performance and each system features a power output of 18 watts per channel. DVD Audio/Video, DVD-R/RW, CD, CD-R/RW, SVCD/VCD, MP3/JPEG/WMA formats are supported. DVD-specific features include Digital Direct Progressive Scan and DVD Express Play Start. An AM/FM tuner completes the package.
The systems' 18 watts per channel are delivered by JVC's Hybrid Feedback Digital Amplifier, which eliminates noise often produced by digital amplifiers by using two feedback systems - one digital and one analog - to ensure the highest quality sound. A 192-kHz/24-bit audio D/A converter and 10-bit/54MHz video D/A converter are also featured for maximum quality. The user interface is rounded out by a display dimmer, electronic bass and treble tone controls as well as random and repeat program modes.
The EX-D1 caters to users who want to play music that is stored digitally on their computers. A USB input connection enables playback of music from a computer with an available USB port.
