Module Description
The IQDMX01 and IQDMX11 are 2/4 x AES/EBU
stream demultiplexers with advanced embedded
audio handling. All audio manipulation is at the
channel-level suiting discreet surround and multilingual use. In addition to its tracking audio delay, it
also has a bulk audio delay feature. To complete
the delay flexibility, it has a built-in video delay that
can be used to adjust to match external audio
processing delays, such as that from a Dolby E
encoder. Its audio firewall capability ensures
continuous audio output even when the embedded
audio signal fails. A dual SDI input allows this
module to take signals from either of two paths
thus allowing split operation, with video taken from
one input and embedded audio from the other.
The IQDMX01 and IQDMX11 can also be used as
embedded audio processors. Their ability to remultiplex the audio internally after channel
manipulation and processing means that they can
be used in this role with the AES outputs used for
monitoring feeds.

Input Select
This allows either Input 1 or Input 2 to be selected
for processing.
Note that as the IQMUX0315-1A and
IQDMUX1315-1A versions have only one input,
Input 1 should always be selected. If Input 2 is
selected the unit will report an input loss.
Input Standard
This allows input standard to be selected.
If only 625 is selected the unit will be forced to only
accept 625 line inputs.
If only 525 is selected the unit will be forced to only
accept 525 line inputs.
If 625 and 525 are selected the unit will accept
both 625 and 525 line inputs.
DeEmbed Select
Either Input 1 SDI or Input 2 SDI may be selected
for DeEmbedding. If Follow Video is checked the
signal selected via the Input Select item will be
DeEmbedded.
Non-PCM groups can be transparently passed but
if a non-PCM group is selected for mixing or
routing it will be automatically muted.
If a Dolby header is detected in the data stream it
will be processed as a non-PCM signal.

ProcAmp
These items allow signal levels and timings to be
adjusted.
Separate adjustments may be made for the two
input channels Input 1 SDI and Input 2 SDI.
Note that for this and other screens the following
applies to the scroll bars:
The and symbols at the ends of the
scroll bar allow the value to be adjusted in discrete
steps.
The numerical value will be shown next to the
scroll bars and selecting Preset will return the
setting to the calibrated value for that item.
Input 1 SDI and Input 2 SDI Controls
These items allow the gain, black level and timing
of both signals to be adjusted.
ProcAmp Enable
When checked the ProcAmp will become enabled
for that channel and the settings will be applied to
the signal.
When unchecked the settings will revert to the
preset values.
Luma Gain
This allows the Y (luminance) gain to be adjusted
by ±6 dB in steps of 0.1 dB. Preset value is 0.0 dB.
Black Level
This allows the black level to be adjusted by
+100mV in 0.8mV steps. Preset value is 0.
C Gain
This allows the Cb/Cr (color difference) gain to be
adjusted by ±6 dB in steps of 0.1 dB. Preset value
is 0.0 dB.
Picture Position
This item allows the timing of the picture position
relative to the normal value, to be adjusted.
The timing may be adjusted by +592ns in 148ns
steps.
Y/C Timing
This item allows the timing of the chrominance
signal relative to the luminance signal to be
adjusted, (i.e. Y to Cb/Cr timing) in nanoseconds.
The timing may be adjusted by +592ns in 148ns
steps.

±18 dB in 0.1dB steps. Preset is to 0 dB.
Invert
When checked the signal polarity will be inverted.
Mute
When checked the signal will be muted.

Audio Mix 1, 2, 3 and 4
There are four separate audio mixers Mix 1, 2, 3
and 4.
Each mixer has four inputs with individual gain
controls that allow the mixing levels for each of the
input signals, to be adjusted. The range of
adjustment is from 0 to –90 dB and to Off.
0 to -60 dB is in steps of 1 dB, -60 dB to -90 dB is
in steps of 3 dB.
The inputs can be selected from the list in the
Source 1, 2, 3 and 4 items.
The outputs of these mixers provide four extra
input selections for the Channel Router.

made to one channel will automatically be applied
to both channels.

Audio Embed
This function sets up the embedder sources and
destinations. Higher number embedders have
priority, so if the same destination pair is selected
on two embedders, the highest embedder will be
the one that is active.
Embedder 1, 2, 3, and 4
The source of the signal for the embedder may be
selected from the list.
Destination 1, 2, 3, and 4
The destination for the embedded signal may be
selected from the list.
Disable 1, 2, 3 and 4
When checked the embedding will be turned off.
Non-PCM Signals
Note that for non-PCM signals sources both
embedders in the group (Group 1 = Embedder 1 &
2, Group 2 = Embedder 3 & 4) should be disabled.
For details of the Audio Embedding Packet
Distribution please refer to Appendix 2 on page 80.

AES Out
This allows the signal source for the AES output to
be selected from the list of items for the two AES
sources. Silence and audio test tones may also be
selected.
Passing Through Embeded non-PCM Signals
To pass embedded non-PCM signals direct to the
AES output DeEmbed (1 to 8) should be selected
from the Source list.
Note that in this mode all processing will be
bypassed.

Audio Delay Setup
This screen allows the amount of delay to be set
and type of audio delay mechanism to be selected.
Manual Delay
This will affect all processed audio signals equally.
The delay may be set to up to +1.5 s in 1ms steps.
Delay Select
This allows the type of audio delay mechanism to
be selected. One or more of the types may be
checked. The amount of delay applied will be the
sum of the delay from the enabled delay
mechanisms.
Note that up to 0.5 s of delay may be applied from
the sum of the GPI + RollTrack delay inputs.
Manual
When checked an audio delay set by the Manual
Delay control will be applied.
GPI
When checked an audio delay will be applied that
is equal to the width of the pulse arriving at the
GPI connector.
Note that an audio delay pulse of more than
500 ms, applied to the GPI Input will be treated as
invalid. This will result in the GPI delay returning to
zero.
Note that the GPI must be configured correctly for
this function to operate. Please see page 30 for
details.
RollTrack 14, 15, 16 and 17
Then selected source(s) of the RollTrack input
signal(s) will apply an audio delay.
Total Delay
This will show the audio total delay (due to all
delay mechanisms) through the unit in ms.

Audio Setup
Audio Monitoring
The four audio buses are monitored and level
detectors provide status information and logging
data.
Silence
The level at which the signal is considered to have
dropped to silence may be set with this control.
The range is from -80 dB to 0 dB in steps of 1 dB.
Preset is to -70 dB.
Low Level
The level at which the signal is considered to have
dropped to a Low Level may be set with this
control.
The range is from -80 dB to 0 dB in steps of 1 dB.
Preset is to -60 dB.
High Level
The level at which the signal is considered to have
risen to a High Level may be set with this control.
The range is from -80 dB to 0 dB in steps of 1 dB.
Preset is to -10 dB.
Overload
The level at which the signal is considered to have
risen to an Overload condition may be set with this
control.
The range is from -80 dB to 0 dB in steps of 1 dB.
Preset is to 0 dB.
Warning Timer
All the above monitoring facilities will only operate
after a time interval set by this control. A valid
signal is reported immediately.
The range is from 1 to 20 seconds. Preset is to 10
seconds.
Audio Tone
The frequency of the Audio Test Tone may be set
using this control. Left and right channels may be
set independently.
Frequency L and R
The range is from 100 Hz to 15 kHz in steps of
100 Hz. Preset is to 400 Hz.
