While shopping for my first CD player, I was able to decipher most of the technicalese on the promotional signs. One designation had me puzzled, though, so I called over a salesperson and asked, What does 'hybrid pulse D/A converter' mean?That means, she said, that this machine will read the digital information that is encoded on CDs and convert it into an audio signal - that is, into music.In other words this CD player plays CDs.Exactly.
