I hear that we're going to have to change our redlight soundtrack readers to a new cyan reading unit. The change is supposed to induce longer reader life and improve performance on all analog soundtracks. Separation is said to be better with lower distortion levels. Has anyone else heard about this and what the cost will be?

Here are some links to information about the upcoming conversion to cyan dye analog soundtracks:

As you can see, there are advantages to installing reverse-scan red LED readers NOW, even with current dye+silver tracks.

So far, two releases have been made with a limited number of cyan-dye analog tracks. These prints were sent to those theatres already equipped with the required red LED readers, and played fine. These trade tests will be scaled up to larger quantities of prints, with 100% cyan dye release scheduled to begin in 2002.

If you have a red light reader then you're already setup (like a sucker) for cyan.

Actually he is not a sucker but someone who probably is quality conciesous
Even if the cyan issue was not involed the dramatic improvement in seperation and tracking and high frequency response of the reverse scan readers is a big plus to any quality oriented theatre
