ENGLISH Cautions on handling • Before turning the power switch on Check once again that all connections are correct and that there are no problems with the connection cables. • When leaving home for long periods of time, be sure to unplug the power cord from the power outlet. • Proper ventilation If the unit is left in a room full of the smoke from cigarettes, etc., for long periods of time, the surface of the optical pickup may get dirty, preventing it from receiving the signals properly. • About condensation If there is a major difference in temperature between the inside of the unit and its surroundings, condensation may form on parts inside the unit, causing the unit to fail to operate properly. If this happens, let the unit sit for an hour or two with the power off and wait until there is little difference in temperature before using the unit. • Cautions on using mobile phones Using a mobile phone near this unit may result in noise. If that occurs, move the mobile phone away from the unit when it is in use. • Moving the unit Turn off the power and unplug the power cord from the power outlet. Next, disconnect the cables connected to other system units before moving the unit. Features Equipped with a USB-DAC function to support DSD file playback This unit is equipped with a USB-DAC function that supports DSD signals and 192 kHz/24 bit PCM signals. You can enjoy high-quality audio playback from this unit's D/A converter by inputting PCM signal or DSD signal music files into this unit from a computer via USB connection. • Install the dedicated driver software onto the computer before use (vpage 20). • You can use whichever commercially available or downloadable player software you like to playback files on your computer. Toroidal transformer This unit features a toroidal transformer that produces less vibration and magnetic leakage flux compared to conventional power transformers. The materials and manufacturing process of the ring-shaped core are strictly controlled to reduce vibration, while the short-ring attached to the perimeter of the transformer reduce magnetic leakage flux. Large-capacitance block capacitor A large capacitance 4700 μF capacitor carefully selected for its acoustic characteristics is incorporated into the power supply circuit. Audiophile-grade film capacitors and electrolytic capacitors The unit's features the same audiophile-grade film capacitors and electrolytic capacitors specifically used in top-range models. Low-noise low-distortion filter circuit and highspeed HDAM®SA2-type output amplifier with the differential input type HDAM® Double-layered chassis High-grade machined analog audio output connectors Playback of CD-R/CD-RW discs (MP3/WMA) and USB memory devices (MP3/WMA/WAV/AAC)/ iPod®/iPhone® Can be used as a D/A convertor Digital audio signals input from an external device or computer into this unit can be converted and output as analog signals using this unit's D/A converter. 3
