User manual HARMAN KARDON A500 SERVICE MANUAL

[. . . ] Harman Kardon's audio/video receivers are the first to integrate MP3 with built-in decoding and both coaxial and optical frontpanel digital inputs. Now, enjoying the wide variety of MP3 audio content is as simple as playing an MP3-encoded CD in a DVD 25 or DVD 101, or connecting the output of a compatible computer sound card to the digital input of an AVR 325, A500, AVR 7200, DPR 1001 or DPR 2001. The Basics of MP3 Audio From a technical definition standpoint, what is popularly referred to as "MP3" is more precisely the "Level 3" format for recording audio in the MPEG-1 video compression standard.

The Basics of MP3 Audio From a technical definition standpoint, what is popularly referred to as "MP3" is more precisely the "Level 3" format for recording audio in the MPEG-1 video compression standard. In simple terms, this means that an MP3 file is a digitally compressed version of an audio track. The original audio may be a file initially created for distribution in the MP3 form, or it may be created from an existing source, such as a CD. The difference between standard digital audio files and an MP3 file is that the average 3-minute song takes up about 32 megabytes of space, but the MP3 takes up considerably less memory, enabling more songs to be placed on a single disc or memory card, with little compromise in sound quality. The compression process relies on oddities of human perceptions of sound. However, both the DVD 25 and DVD 101 are capable of recognizing and playing MP3 audio files from compatible discs. Both models decode MP3 files and play them through the unit's analog outputs for easy connection to ANY audio system. With a single MP3 disc able to hold about 10 hours of music in the MP3 format, the DVD 25 and DVD 101 can keep the party going all night with just one button press. Benefits While the MP3 format has helped increase the availability of audio selections, until now it has been limited to playback through computer audio systems and portable devices. Now, Harman Kardon allows you to benefit from the high storage capacity and wide variety of material made possible by MP3 through the high-quality amplifiers and speakers in your home entertainment system. From direct connection to a compatible computer sound card or MP3 player, to playback of prerecorded MP3 CDs, to recording of MP3 tracks in standard CD-format mix discs, Harman Kardon is the leader in expanding applications of MP3 for use throughout the home.
