8.6 Setting and Adjusting the Audio Delay Time
You can adjust the S/PDIF audio delay time for OUTPUT 2 to correct lip
sync errors so that the audio delay will match the video delay. The delay time
can be set and stored separately for each input channel.
To set or adjust the audio delay, do the following:
1. Press the DELAY button on the front panel.
The DELAY button blinks; the 7-segment display shows the sampling rate (in
kHz) and the delay time in milliseconds.
2. Press the STO/+ and RCL/- buttons to increase or decrease the delay time 1
respectively.
3. Once the delay time is set, press the DELAY button again to accept the delay
time value.
The DELAY button illuminates and the 7-segment display goes back to
displaying the inputs switched to the outputs.
The maximal delay time is set according to the input sampling rate 2 , as
described in Table 8:
Table 8: Maximum Delay Time according to Sampling Rate
Sampling Rate
[kHz]
Maximum Delay Time
[msec]
32 999
44 740
48 680
96 340
To cancel the delay time, press the DELAY button once again.
The DELAY button light turns off.
To reset the delay time to 0 (zero), press and hold the DELAY button for a
few seconds.
Table 9 summarizes the way the DELAY button responds:

Blinks You can view the sampling rate and the delay time
value, or adjust the delay time
Illuminates OUTPUT 2 audio delay is on
Is not illuminated OUTPUT 2 audio delay is off
Is pressed for a few seconds Delay time resets to 0 (zero)
1 Press and hold the STO/+ or RCL/- buttons for a faster increase or decrease of the audio delay time respectively
2 The sampling rate is specified by the source signal and cannot be changed by the switcher. The switcher automatically
adjusts the maximum delay time value according to the sampling rate
