Audio Setup Window
The FRS-1002 card supports 16 audio channels in 4 groups of PCM-20
bits and PCM-24 bits encoded audio at 48KHz.
The Audio Setup window allows the configuration of audio parameters
(16 channels, 4 groups) affecting the individual channels of the card.
Audio on Lost Video
When the video input is lost or when a signal reference mismatch occurs
the FRS-1002 responds with an action set by the user in the Video Default
Mode function for video, and in the Audio on Lost Video function for
audio. The audio data can be muted to prevent undesirable noise at the
output, or a standard audio 1 KHz test tone can be inserted.
In the Mapping tab, select the Audio on Lost Video to choose from:
• Mute all outputs
• Test Tone (1KHz)
Audio Delay Mode
An audio delay can be specified by the user for each video input channel.
Two modes are available in the Audio Delay Mode function. Select
from:
• Follow Video
• Custom
Follow Video, the audio delay is automatically adjusted to match the
video delay.
Custom, the audio delay is set by the user independently from the
video delay. The delay can be set in audio samples increments or in 1
millisecond increments.
