The Duck value sets the amount by which the background audio level is attenuated when the voice-over is fully on.
The Preset value sets the level of the voice-over audio when the voice-over is fully on. Both values are measured in
decibels.
Up to 8 independent voice-overs may be defined via the Configurator Tool Route Manager (see section 7.4.2).
4.5.4 Easyplay
Note:
Easyplay audio clip playout requires version 3.1 software or above and is only supported by LGK-3901.
The Easyplay feature allows digital audio clip storage and playout of up to two independent streams sharing a total of
eight audio channels. This allows for a range of possible cases including:
•
8 channels
One stream playing out wide audio clips
•
5.1
Two streams of the same language with different widths
•
2 x stereo
Two streams of different language under independent control
Easyplay audio clips are typically associated with one of the 8 available voice-overs. The associated voice-over is
then automatically faded up when the Easyplay stream starts playing, and automatically faded down when the
Easyplay stream stops.
Easyplay may be set up to automatically follow corresponding video layers cuts, fades, loads and unloads. In this
mode, audio clips are loaded by association with image filenames, and audio clips will play out (or stop) automatically
when an associated keyer is cut up (or down). Association may be made with either Program or Preview keyers.
The following Easyplay audio clip file formats are supported:
•
OXW
2 channel clips created by AudioBuilder (available from the MCS CD)
•
WAV
Multi-channel WAV files (preferred)
All audio clips must be generated at 48 KHz (samples/second). WAV files may be generated with 16 bits or 24 bits
(preferred) per sample.
4.6 Video AB Mixing
Video AB mixing requires the AB mixing option (LGK-3901-OPT-ABMIX or DSK-3901-OPT-ABMIX).
The integrated video AB mixer allows video from two SDI inputs (PGM IN and FILL-2) to be mixed together. The
resulting mix provides the background video source for the PGM keyers, as shown in the functional block diagrams on
pages 3 and 6. The mixer may be dynamically configured to either cut or fade the video. Cross-fades and V-fades are
supported over variable durations, with V-fades transitioning through a predefined color field. V-fades may be
performed asymmetrically for “cut-fade” or “fade-cut” transitions.
Audio AB mixing requires the video AB mixing option plus the audio option (LGK-3901-OPT-AUD or DSK-3901-OPT-
AUD). The audio mix may be configured to automatically follow the video mix (SETUP > AUDIO SETUP > FOLLOW
VIDEO > A/B MIX), or can alternatively be controlled completely independently from the video.
