Advanced Sound Retriever
Hear the detail, warmth and clarity, the way the artist intended it, from all of your highly compressed MP3, WMA and AAC files stored on USB memory device, iPod® and portable digital players. By restoring data (especially higher frequencies) that tend to get lost in the digital compression process, Pioneer’s Advanced Sound Retriever technology enhances audio reproduction nearly all the way up to 20 kHz frequencies.

When Advanced Sound Retriever is “ON”, the high frequency range is compensated to match the frequency response curve of the original sound.

USB Direct Control for iPod® and more
Pioneer's DEH-P4000UB is ready to roll with capability for direct connection to your iPod®. USB 2.0's speed and capability allow an elevated iPod® experience in the car, and nearly limitless expandability for portable media players and USB memory devices.

File search and access are extra-quick. The headunit keeps song, artist, time and album information displays very clear and user-friendly, and control is intuitive through the 7-Way Rotary Commander. The system's wired USB connection provides direct digital signal transfer from the iPod® for clean, clear sound. In addition, Pioneer has developed the following new features to make using your iPod® in the car extremely easy and convenient:

• Link Search
  While listening to a specific artist you can hold "List" button down and it will pop up folders containing that specific artist.
• Passenger Control Mode
  Allows passenger to use the iPod® directly to browse and select music, while connected to the headunit for playback.
• Random (Shuffle) Key
  Physical Random Button on faceplate (Shuffle) makes it easy to hear something fresh.
