Front Panel Menu Summary
Command Function Options/Response Format
Determines how often the
SE4000 samples the analog
waveform during the audio
analog to digital conversion
process.
Sample Rate
Additional Information: Selecting
a high audio sample rate will
produce a high-quality audio
signal at the output audio device;
however, a high audio sample
rate reduces the total transport
stream bit rate available for the
video signal. An audio sample
rate should be selected that
meets the audio requirements
while allowing sufficient
bandwidth to meet the video
requirements.
32, 44.1, 48 kHz
default: 48 kHz
Delay Sets the compressed audio bit
stream buffer delay, which
controls the time delay between
the audio and video.
-300 to 300 milliseconds
default: zero (0) msec
? Positive numbers cause the decoder to delay
the audio output with respect to the video (i.e.
lag).
? Negative numbers cause the decoder to
advance the audio output with respect to the
video (i.e. lead).
? Zero (0) represents nominal alignment between
video and audio output from the decoder (i.e. lip
sync). In addition, a zero lip sync value
assumes that the video and audio has lip sync
at the input of the encoder.
SDI Channel
Pair
Selects one of the eight
embedded audio channel pairs
associated with the digital audio
input
Note: SDI Audio Chnl Pair is
only available when digital
audio channels are selected.
1 through 8
default: 1
Output
Resolution
Query-only; displays the number
of bits per audio sample.
16-bit, 20-bit, 24-bit
