Introduction – general use The SDDS sound format SDDS (Sony Dynamic Digital Sound) is designed to reproduce up to 8 channels of high quality audio in cinema theatres. The audio data is stored on the film strip, on both outer edges, outside the perforation holes.

If the Data present indicator is off, the film is not running through the reader at the right speed. If it is flashing, the film is running, but no SDDS data can be decoded. When it is solidly on, the unit plays back SDDS through the sound system unless the bypass button has been activated (button is lit).
Maintenance Reader The SDDS reader lenses and the light source fibre optics must be kept clean at all times. A combination of using a blower brush and cotton buds is recommended for this purpose. See the SDDS Quick Reference Guide for further details about cleaning the SDDS optics. Additionally, the entire reader film path must be kept clean at all times.

Decoder The air intake filter of the SDDS decoder must be kept clean at all times to avoid that clogging stops the airflow. Open the front panel of the DFP-2000 decoder and remove the air filter in the front panel door, clean it and re-insert it.
Therefore, it is instrumental that you let your print provider/film distributor know to make sure that such issues are resolved. Additionally, you may fill in the SDDS Film Print Form and send to Sony to make us able to provide technical assistance to the relevant laboratory.
