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 multi-
lingual 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 re-
multiplex 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.

When checked the output picture will become a

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.

This allows control of Gain, Mute, and Polarity over
the de-embedded channel pairs.
L and R
These scrollbars allow the gain of the Left and
Right channels to be adjusted over a range of
±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.
Stereo
When checked the left and right channels will be
configured as a stereo pair and any adjustments
made to one channel will automatically be applied
to both channels.

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.
