Many year ago, 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", he 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."
