The total delay time through the audio delay is then the sum of the individual delays introduced by the video
units plus the manual delay of the audio unit. The manual delay can be set to compensate for any fixed
propagation delay in the video path or may be set to zero.
The next level of complexity is a
matrix delay cluster where each audio delay (up to eight) can track up to four
video units. This configuration is in effect a four by eight matrix of video units and audio delay units. The total
delay time through the audio delay units is then the sum of the individual delays introduced by the video units
plus the manual delay of the audio unit.

As any of the delay times change in the video path so will the audio delay time track this delay.
A virtual connection is made between from, say, an IQD1FSY to an IQBDAD by:
selecting the
Setup... Menu of the IQD1FSY
then selecting the
Audio_Delay... Menu
then choosing from
Unit_1 to Unit_8
then entering the unique network address of the IQBDAD in the form
nnnn:xx:yy*z*d
where
nnnn = network address and in most cases will be 0000(hex);
xx = IQ enclosure address (hex);
yy = slot address of the IQBDAD (hex)
z = the connection (or channel) number (decimal) - see table below.
d = the unique identification of the destination unit (decimal) The ID entered must match the
receiving units own ID or else the command will be ignored. If the ID value is set to 00, the
receiving unit does not perform an ID match and will always accept the incoming command
then selecting the
Delay... Menu of the IQBDAD
then selecting
Auto
