IQMUX34 Introduction
Issue 1 Rev 5 Page 5 © 2018 SAM
1. Introduction
1.1 Description
The IQMUX34 provides 4 or 8-channel analog audio multiplexing for HD-SDI 3 Gbit/s, 1.5
Gbit/s, or 270 Mbit/s SD-SDI signals. Audio processing features include audio delay, gain,
invert, and channel level routing, while video delay and a video proc. amp are also included in
the feature-set.
1.2 Block Diagram
1.3 Feature Summary
• 4/8-channel 3G/HD/SD-SDI multiplexer for analog audio inputs - via 25-way D-Type
(8-channel) or screw terminals (4-channel)
• Standards supported:
• 3G-SDI to SMPTE 424M/425M level A & B compatible
• HD-SDI to SMPTE292M/274M/296M
• SD-SDI to SMPTE259M-C
• Handles up to 16 channels of embedded audio present on the incoming SDI stream.
• Includes independent gain, invert, mute controls, channel level (sub-frame) routing,
and adjustable delay for selected audio channels.
• Embedding continues on loss of SDI input (silence).
• Any group of embedded audio may be passed unchanged, processed, or blanked.
• Embedded Dolby E support – pair routing and delay.
• Up to nine frames of video delay and two seconds of audio delay.
• Video controls including video gain, offset, HANC and VANC blanking control.
• Input loss detection – default output of black/pattern.
• Transparent to all ancillary data inc. VANC metadata.
• In-built test pattern generator and audio tone generator.
• 16 user memories, save/recall/rename.
• Rollcall control and monitoring compatible.

1.4 Order Codes
The following product order codes are covered by this manual:
1.5 Rear Panel View
The following rear panel types are available:
Note:
Modules with “A” order codes (for example, IQMUX3449-1A3) can be fitted into either A- or
B-style enclosures. Modules with “B” order codes (for example, IQMUX3449-1B3) can only
be fitted into B-style enclosures. See page 7.
IQMUX3449-1A3
IQMUX3449-1B3
3G/HD/SD-SDI 8-channel analog audio multiplexer. 2 SDI inputs, 2 SDI
outputs, 8 balanced analog audio inputs.
IQMUX3451-1A
IQMUX3451-1B
3G/HD/SD-SDI 4-channel analog audio multiplexer. 2 SDI inputs, 2 SDI
outputs, 4 balanced analog audio screw terminal inputs.

IQMUX34 Introduction
Issue 1 Rev 5 Page 7 © 2018 SAM
1.6 Enclosures
The module can be fitted into the enclosure types shown.
1.6.1 B-style Enclosure
Enclosure order codes: IQH3B-S-0, IQH3B-S-P
1.6.2 A-style Enclosures
Enclosure order code: IQH1A-S-P
Enclosure order codes: IQH3A-S-0, IQH3A-S-P
Enclosure order codes: IQH3A-E-0, IQH3A-E-P, IQH3A-0-0, IQH3A-0-P
Enclosure order code: IQH1A-S-P
Important:
Although IQ modules are interchangeable between enclosures, their rear panels are
enclosure specific. An IQH3B enclosure accepts modules with either “A” or “B” order
codes. An IQH3A or IQH1A enclosure accepts modules with “A” order codes only. See
page 6.

5.2 Video
The Video screen enables you to specify the following settings for the selected serial data
input:
• Valid input standards
• The default output standard
• Any required ancillary blanking
• Freeze options on the output image
• The default output
5.2.1 Input Select
The Input Select control selects either Input 1 (at connector SER IN 1) or Input 2 (at
connector SER IN 2) to be processed by the module.
5.2.2 Valid Input Standards
The Valid Input Standards check boxes specify the video input standards that the module
will accept. The module will automatically detect the standard of the received input and block
any signal that does not comply with these selected video formats.
By default, all input standards are selected.

Issue 1 Rev 5 Page 16 © 2018 SAM
5.2.3 Default Output
The Default Output control specifies the module’s output in the event of signal loss at the
input. Options are:
•Black: video out is a black screen.
•Freeze: video output is frozen/paused.
•Pattern: video output is a pre-determined test pattern or information screen.
5.2.4 Default Output Standard
The Default Output Standard settings specify the output standard that the module will use if
it cannot determine the correct output standard to use.
By default, the Last Known Good setting is selected, which uses the last valid output
standard.
5.2.5 Blanking
The Blanking controls enable specific lines of VANC to be blanked.
•625 blank lines: Applied to 625 only, you can blank either or both of line 23 or line
336.
•525 blank lines: Applied to 525 only, you can blank any or all of lines 21, 22, 283, or
284.
•Blank VANC: Selecting this option blanks the following lines inclusively:
All VANC data from the end of the last active video line to the end of the RP168 switch
line is always blanked, irrespective of this control.
•Blank HANC: Selecting this option removes all horizontal ancillary data including
audio when the embedders are disabled and the audio is unprocessed.
5.2.6 Freeze
The Manual Freeze control freezes/pauses the output. Freeze type can be specified as either
Field or Frame.
525: 11–20, 274–282
625: 7–22, 320–335
720: 8–25
1080i: 8-20, 570–583
1080P: 8–41
Note:
This function is disabled on a power-cycle of the module.

• Black Level
• Hue Adjust
• Master Video Gain
• Y Gain (Luma)
• Cb/Cr Gain (Chroma)
• Y/C Timing
• Picture position
5.3.1 Procamp Enable
The Procamp Enable check box enables the video processing amplifier functions. Clear the
check box to disable the Procamp functions.

The Black Level control allows the channel’s black level to be adjusted over a range of ±100
mV in steps of 0.8 mV. The preset value is 0.
5.3.3 Hue Adjust
The Hue Adjust control allows the channel’s hue to be adjusted over a range of ±180° in
steps of 1°. The preset value is 0.

5.3.4 Master Video Gain
The Master Video Gain control allows the video gain to be adjusted over a range of ±6 dB in
steps of 0.1 dB. The preset value is 0.
5.3.5 Y Gain
The Y Gain control allows the luma to be adjusted over a range of ±6 dB in steps of 0.1 dB.
The preset value is 0.
5.3.6 Cb/Cr Gain
The Cb/Cr Gain control allows the chrominance to be adjusted over a range of ±6 dB in steps
of 0.1 dB. The preset value is 0.
5.3.7 Y/C Timing
The Y/C Timing control allows the luma/chroma timing to be adjusted over a range of:
• ± 8 pixels in 2 pixel steps in SD
• ± 16 pixels in 2 pixel steps in HD/3G
The preset value is 0.
5.3.8 Picture Position

5.4 Video Delay
The Video Delay screen enables the video delay mode to be specified.
5.4.1 Horizontal Delay
Use the slider bar to adjust the horizontal delay over a range of 0 to 1 line in 1 pixel steps. The
preset value is 0.
If the delay is set to lower than the latency, the delay will stop at the latency but this will not be
indicated. Additionally, if the vertical delay is set to 0, the lowest horizontal delay will equal the
latency of the module rather than the delay specified by this control.
5.4.2 Vertical Delay
Use the slider bar to add up to 1 frame of vertical delay in steps of 1 line. The preset value
is 0.
5.4.3 Frame Delay Added
You can specify up to nine additional frames of delay using this slider bar.
The delay of non-PCM audio, or ‘pass-through’ audio is also set by this control.
The delay, in ms, is displayed below this control.
5.4.4 Active Video Delay
The total active video delay (in ms) is displayed at the bottom of this screen.

5.5 Embedder 1 to Embedder 4
Four embedder groups are provided. Each embedder group comprises two stereo audio
pairs, each of which has a left and right channel. The settings on these screens enable you to:
• Enable or disable the embedder group
• Apply a mute to a pair within the group
• Configure each pair as either 2 Channel, Stereo, or Non-PCM
• Configure each channel within the pair
• Specify the route for each channel
With the exception of the Embedder Enable control, each control is duplicated for Pair 1 and
Pair 2.
5.5.1 Embedder NEnable
This option, when checked, enables the embedder group.
Note:
The control templates for Embedder 1 to Embedder 4 comprise the same controls. To
avoid repetition, the controls are only described once in this manual.
