New & Improved!! Codename Turquoise now comes Ready Made --
Two Pre-cut Rings that fit the two inner circular areas of the CD Tray.
Also available as single Pre-cut Ring for Top Loaders.
Codename Turquoise, a revolutionary new product from Machina Dynamica, is a CD Tray Masking System designed to absorb scattered background laser light, dramatically improving the optical performance of the player. The location of Codename Turquoise - in close proximity to the CD and the laser - ensures that the scattered light absorption occurs at the most critical time for the best optical performance. Codename Turquoise is attached to the top surface of the CD tray using a semi-permanent, removeable adhesive that is supplied with the color coded rings. For top loaders, a single ring is attached to the surface of the player around the CD spindle.
Theory of Operation
Laser light is refracted and scattered while the laser is reading the data on the dics. Refraction occurs when the CD laser beam strikes the edges of the physical "pits" of the data. This scattered light is coherent, thus in the form of waves that produce reinforcement peaks that interfere with the primary laser signal. The photodetector is constantly picking up "False Positives" since it doesn't discriminate between the "real signal" reflected back from the metal layer and the "false signal" of the scattered light peaks. False Positives occur whenever the background light intensity exceeds the threshold of the photodetector (about 75% power of the primary laser beam). It can be demonstrated experimentally that False Positives occur continuously for all CD players. Codename Turquoise eliminates these False Positives, allowing the optical reading of the disc to be 100% efficient for cleaner, clearer, more dynamic sound -- like the master tape.

NEW!! Codename Turquoise for Top Loaders - one-piece ring fits the area around the CD spindle with cut-out for laser assembly. $59 + shipping ($5 Priority Mail in US).
NOTE: Use Machina Dynamica's Codename Top Banana For all Blu Ray and HD-DVD players.
Codename Turquoise Masking Kit consists of 2 Pre-cut Rings of Special Color-Coded Paper and a semi-permanent adhesive for securing the rings on the CD tray. The adhesive will not harm the CD tray surface and the paper rings can be easily removed at a later date if desired.
NOTES: NOTE 1 - The Rings will fit a "standard" CD tray perfectly; however, for some CD trays, the tips of the rings might have to be trimmed so the tips do not protrude into the cut-out section of the tray where they could interfere with laser reading of data. NOTE 2: One Marantz CD player tray uses a special silver paint that is known to react with the semi-permanent adhesive provided in the Masking Kit; therefore, Codename Turquoise cannot be used with that particular Marantz CD player. NOTE 3: Some CD burners and Universal players do not provide sufficient clearance in the tray area to apply the Codename Turquoise material.
