Technical Specifications
Inside an Imagestore 750 that is equipped with a Dolby kit, there is a Dolby carrier card which
has 4 slots available for Dolby or upmix modules. There are no specific slots for decoder or
encoder modules because the Imagestore 750 detects the modules’ presence and type
automatically.

• Dolby Digital encoder module.
