X75HD/X75SD Installation and Operation Manual 149
Chapter 8: Video Configuration
Receiver
The V2A receiver simultaneously monitors the inputs to the X75’s
audio sources and compares them against one of the unit's video inputs.
To configure an X75 unit for V2A reception, follow these steps:
1. Route the audio inputs containing V2A signals to the SRCs to be
used in the unit's final processing (see “Selecting an Audio Source”
on page 153 and “Advanced Audio Inputs and Outputs Selection”
on page 160 for details).
2. Select a video input under the Video/Audio Timing>V2A Rx
Video Src parameter.
For analog and HD inputs, the source will be that which is currently
selected in the X75A3D/X75PQM and X75HD submodules
respectively.
Parameters under Video/Audio Timing>V2A Status indicate whether
or not a valid V2A test signal is detected on the unit's inputs. If a valid
V2A test signal is detected, the relative video delay will be indicated by
a series of parameters under the Video/Audio Timing>Video Delay
sub-menu. A series of parameters under the Video/Audio Timing>
Channel Swap sub-menu report whether or not the unit detects a left/
right channel swap for stereo pairs.
You can automatically set the measured video delays to the unit’s audio
delay parameters using the Video/Audio Timing>Align Leading
Audio parameter. Setting this parameter to Ye s updates the unit’s audio
delay parameters with the currently displayed V2A video delays,
effectively compensating for measured video/audio timing differences.
Note
To prevent processing errors,
you must ensure all unused
audio channels are routed to
Tone or Mute. The receiver
takes approximately 5 seconds
to generate audio/video timing
information for all of the inputs.
