Forward
Several years ago, one of the most successful radio stations in North America was
CKLW in Windsor/Detroit. Innovative, technically superb audio complemented “The
Big 8”’s excellent execution of their Top 40 program format to give the station a big
signature sound that I have never forgotten. Its striving for perfection has been an
inspiration and has influenced the goals, designs, and sounds of many Orban Opti-
mod products to this day.
If it weren’t for CKLW’s innovative audio texture and the chances that it took to ex-
pose the world to many great artists, these discoveries would never have become
part of the radio and music history that they now are. Just as many of these great
artists have moved on from creating hit music to fusing their old styles with newer
forms such as smooth jazz, Orban is evolving by giving the world new viable broad-
cast technology that build on its legacy.
I dedicate this technical manual to CKLW and those who made it the reality it once
was, and to Leo, my faithful dog, who was beside me, night after night and day af-
ter day in the long process of preparing this document.
As the world moves on embracing innovative ways to deliver audio to an audience,
“ladies and gentlemen, the beat goes on…” – Bill Drake, radio programmer
