User Manual
The Imagestore 750 has built-in video delays that allow you to compensate for this delay. This is
described, for Dolby modules, in
Audio Delays on page 146. The same principles apply to up-
mix.
Upgrading Up-Mix Module Firmware
Firmware for the up-mix modules is included within the Imagestore 750 software release. A
module’s firmware will be upgraded automatically during a software update, but only when an
update is required.
 Note: Each up-mix module firmware upgrade can take 3 or 4 minutes to complete. Therefore
the overall software upgrade time could be extended by up to 16 minutes.
Please monitor the progress of the upgrade on the Imagestore 750’s front panel. Do not power
down the Imagestore 750 too early because doing so can render the Imagestore 750 inoperable.
Throughout the upgrade, progress is reflected on the front panel of the Imagestore 750. The
panel indicates which software/firmware file is being loaded.
For up-mix modules, the panel shows the firmware upgrade as ‘Load up-mix’.
Configuring Up-Mix
The ‘Audio Graph’ page of the Imagestore 750 Configurator is the recommended tool for
designing audio configurations that incorporate up-mix modules. See
Audio Graph on
page 161.
Imagestore 750 Configurator
In the Imagestore 750 Configurator, you can do the following:
• Draw the audio configuration, connecting audio inputs and outputs and other audio blocks
to up-mix blocks.
• Draw Dolby metadata configurations and connect any required metadata to up-mix mod-
