The player includes SonicStage software, which lets you take full advantage of ATRAC3plus (Sony's proprietary music-compression technology) when making custom MP3 CDs on your computer. Playback options include 32-track programming, repeat (track, disc, or program), random play, and--thanks to Sony's great work in DSP efficiency--more than 85 hours of ATRAC3plus CD playback or up to 50 hours of audio CD playback on two AA batteries (not included).Using SonicStage Software SonicStage allows you to rip audio to your computer CDs and the Internet and then transfer it to an ATRAC3 or ATRAC3plus-encoded CD. These encoded CDs can hold as many as 490 songs. The D-NF400 offers a two-line dot-matrix display, full ID3 tag recognition, and bookmark playback (which lets you program your favorite songs from multiple CDs and play them back at the touch of a button). CD Text support displays artist and title information for compatible commercial audio CDs. ATRAC3plus is a high-quality audio-compression technology that reduces the size of digital audio files while preserving much of a track's original sound quality, similar in concept to the MP3 or Dolby Digital sound formats. With ATRAC3plus, music can be burned and compressed at 132, 105, 66, 64, or even 48 kilobits per second (kbps), letting you select the right balance between fidelity and storage space (you'll get around 490 songs per disc at 48 kbps). MP3 compatibility extends from 16 to 320 kbps files. The player comes bundled with Sony's SonicStage CD Simple Burner software. Compatible with ID3 tagging and most CD burners, this application transfers songs from CDs or MP3s on your PC's hard drive and burns them to CDs using ATRAC3plus compression. The D-NF400 offers a whopping 51 station presets, which works out to 30 FM, 10 AM, 4 weather-band, and 7 TV stations so you're never far from your favorite channels. You can hook the player up with your home system through an optional analog stereo "Y" interconnect. Skip-Free G-Protection technology boosts the laser pickup's shock protection to minimize read errors that would otherwise interrupt your music, providing quick recovery from both horizontal and vertical shocks. The D-NF400's heat-resistant lid helps protect the player against high temperatures, especially when you're using it outdoors or in a vehicle. Digital Mega Bass Sound boosts your music's low end without the loss of high clarity or the addition of low distortion, and there's also a built-in equalizer with three preset curves and one customizable setting. Sony's automatic volume limiter system conserves batteries--and guards your hearing--by capping your listening level at either of two settings. The player works with an optional AC/DC 4.5-volt power adapter (AC-E45HG or -E45A). What's in the Box The CD player, MDR-027LP stereo headphones, a CD-ROM (SonicStage software), a user's manual, and warranty information.
