CD-RK Series Features

Pure Direct
 
The CD-S300RK and CD-C600RK offer the same Pure Direct feature popular in Yamaha amplifiers and receivers. Pure Direct is a special listening mode which ensures the highest quality analog audio output. Pure Direct shuts down the digital audio output with the press of a button on the front panel or the remote control and turns off the display thus achieving the lowest possible noise interference.
 
USB port on front panel for iPod and other devices
 
The USB port facilitates high quality sound playback from MP3 or WMA digital music files stored on USB players and memory devices on memory cards connected to USB card readers and of course on CD-R/RW discs. An iPod too connects to the USB port via USB cable for instant playback through an audio system. The digital signal is generated by the CD player with no degradation or jitter converted to analog by the high performance DAC and transmitted to the amplifier via high quality audio circuitry for the ultimate in music playback fidelity. Play pause skip and forward/backward using the remote control. Song artist and album names are displayed. Compatible with the iPod classic (including the 120GB classic) iPod nano (2nd 3rd 4th generation) and iPod touch (1st and 2nd generation). Charges the iPod automatically when the power is on and USB mode selected.
