• 1RU overall video/audio solution.
• ‘Audio Graph’ page, for setting audio configurations, in the Imagestore 750 Configurator.
Note: When Dolby E or Dolby Digital (AC-3) is fed into the AES inputs, the signal is reported as
‘Non-Audio’. This is because Imagestore 750 is unable to detect Dolby E or Dolby Digital (AC-3)
on its AES inputs and so treats it as non-PCM.
Decode and Encode Combinations
The Imagestore 750 accepts up to 4 Dolby decoder/encoder modules. The modules provide
decoding of Dolby E, and encoding of Dolby E or Dolby Digital.
The Dolby option’s product codes cover various cases by allowing combinations to be built. (See
Product Codes on page 111.)
The table below summarizes some of the possible decode/encode use-case combinations:
