Imagestore 2/3
A/B mix mode provides two stereo pair voice-overs that can be inserted into
the result of the mix. The voice-over in the A/B mix mode is named Voice-
Over 1.
Two voice-over mode provides four stereo pair voice-overs that can be
inserted into the background or program audio. The Voice-overs in Two
voice-over mode are named Voice-Over 1 and Voice-Over 2. This mode is
rarely used since one SDI input is lost to provide inputs for the second voice-
over.
Imagestore 300[+] and Imagestore HD-TV
There are two voice-overs (one of which may be an Easyplay voice-over).
Each voice-over which may contain multiple channels. There is therefore no
concept of being able to control separate stereo pairs within a single voice-
over like with Imagestore 2/3.
Each voice-over has two parameters that need to be considered. Firstly the
‘Duck Level’. Duck level is the amount by which the background audio is
attenuated by when a voice-over becomes active. This level is measured in
dB. For example, when the voice-over is on, the background ‘ducks’ by –
12dB.
The second parameter to consider is the voice-over preset. This represents the
level of the voice-over audio when the voice-over becomes active. For
example, when the voice-over is on, the voice-over audio comes up to 0dB.
These levels are represented by the following diagram:
