Audio Settings: The Kenwood Excelon KDC-X502 offers a variety of audio settings to further enhance your music listening experience.
- Sound Reconstruction: When MP3, WMA, AAC files encoded at a low bit rate (less than 96 kbps, 44.1k, 48kHz) are played, the Sound Reconstruction function restores their high frequencies so the sound quality is closer to files encoded at a high bit rate. The processing is optimized for the compression format and the bit rate used. When Sound Reconstruction is Off, the unit plays the original sound stored in the audio file.
