voice-over control via VO2. Dual voice-over versions offer independently
controllable voice-overs on both VO1 and VO2. In addition to the PresMaster
control, the shuffles required to manipulate each of the voice-over effects can
be triggered from sources such as automation and GPI macros. The Easyplay
versions of the mixfiles allow six Easyplay channels to be inserted onto the
output of the AB mixer via voice-over 1.
Preview Modes and Metering
Preview modes enable monitoring of different stages of the audio stream
from input to final output. This monitoring can be audible (via the preview

preview output and meters 1-8, the 5.1 surround mixfiles offer the following
preview modes:
• Mix preview
• PST input preview
• PGM input preview
• VO1 mix / Easyplay preview
• VO2 mix preview

As with all mixfiles for the Imagestore, delay banks are available to allow for
the propagation delay introduced by a DVE effect. As with other mixfiles,
each group of output channels is given its own delay bank of four channels.
Details about how to adjust these delays is provided in the Automation
Protocol Document available from the Miranda Technologies website.

other content (e.g. DolbyE streams and alternate languages) to be embedded
on the program output via the delay banks. It is also possible to route a copy
of the pass-through audio to the preview outputs by using preview mode 8.
Note Preview mode 8 is not part of the standard preview modes but can
be activated (using the automation or GPI) with the ‘j6’ command:
