The CD-324M 200-disc changer offers some truly useful features. Digital Filter removes unwanted digital artifacts from the signal while it is still in the digital domain, allowing the use of gentler-sloped, better sounding analog filters. Digital to Analog Converter converts digital data into an analog music signal. Noise Shaping shifts digital noise (created in the D/A conversion process) beyond the threshold of human hearing, reducing distortion and improving dynamic range. Precision Digital Timing (DPAC) is a high-precision master clock circuit that is isolated from signal-processing circuits to eliminate interference. This ensures that digital information is processed at exactly the same rate as it was recorded, eliminating jitter (time-based errors that make music sound harsh). Fast-Forward/Fast-Reverse audibly plays tracks during fast-forward and fast-reverse, making it easy to search for a particular part of a song.Best Selection File lets the user program up to 32 tracks from any discs in the player for playback as a group by pushing one button. CD Text displays text from encoded CDs on the unit's display. Text can include disc/song title and artist information, as well as disc genre (for example, 'Jazz', 'Classical', etc.). Disc Naming lets the user program a title for each disc. The CD player reads the disc data and displays the name in its LCD display. Disc Sensing automatically detects which disc positions are occupied when the access door or tray is closed. One-Touch CD Recording (CCRS) scans the CD, determines its dynamic range, sets the optimum recording level, then activates the recording process with the touch of a single button.
