Chapter 2: Installation
Installing the Module
The APM6800+/APM6801+ modules have a double-width back module. Due
to high levels of heat dissipation, the modules should not be installed in frames
without fans. The modules cannot be installed in FR6802+DM and 6800/7000
series frames.
These modules require no specialized installation or removal procedures.
However, if you are installing both front and rear modules, ensure that the back
module is installed first before plugging in the front module. Likewise, ensure
that the front module is unplugged from the frame before removing the rear
module. See your Frame Installation and Operation Manual for information
about installing and operating an FR6802+ or FR6822+ frame and its
components.
An FR6802+RM (Rear Support Extension Rails for 6800+ series frames)
option is recommended for APM6800+/APM6801+ modules. See your Frame Installation and Operation Manual for installation instructions.
Upgrading Module Firmware
This module’s firmware can be updated using CCS Pilot, CoPilot, or Navigator
version 3.1.1 or higher, or the HTTP software upgrade tool. In order to perform
these upgrades, your frame must be equipped with a 6800+ETH module. See
your frame manual for more information.
Firmware upgrades for the APM6800+/APM6801+ can also provide firmware
upgrades for the Neural audio processing submodule. In the event firmware for
the submodule is upgraded, the module will take approximately 2.5 minutes to
fully start up while new firmware is loaded. During this time the card-edge
LEDs will flash back and forth. Once this time has elapsed the module will
become controllable. Subsequent module start-ups will resume to the normal 8
seconds.

Operating Notes
When setting the control parameters on the APM6800+/APM6801+, observe
the following:
•If you make changes to certain parameters, other related parameters may
also be affected.
APM6800+/APM6801+ Installation and Operation Manual19
•When you change a parameter, the effect is immediate. However, the
module requires up to 20 seconds to save the latest change. After 20
seconds, the new settings are saved and will be restored if the module loses
power and must be restarted.
•Terminate any unused coaxial output connectors with a 75Ω connector.
•If the required video reference is not present when you are operating
APM6800-D2+D/APM6801-D2+D, the free-running reference that is
specified in the Frame Rate parameter is generated to permit the encoding.
(For more information about Encoder parameters, see Table 4-4 on
page 38.)
•When Input 2 (Module) is selected for the DARS Input Select parameter,
the DARS input on the breakout cable (Input 1) becomes a DARS output.

There are two ways to change the parameters that control your module’s
operation: CCS software applications and card-edge controls.
Using CCS Navigator, you can view, set, and confirm your module’s parameter
settings from your computer’s monitor. Using the card-edge controls, you can
set parameters using the module’s rotary hex and navigation switches.
You can use the information in this chapter to configure and operate your
module using a CCS software application or the module’s card-edge controls.
For more information about setting parameters using the software application or
by using the module’s card-edge control, see “Changing Parameters Using CCS
Navigator” on page 20 and “Changing Parameter Settings Using Card-Edge
Controls” on page 21.
A complete list of APM6800+/APM6801+ control parameters can be found in
“Chapter 4: Parameters, LEDs, and Alarms” on page 27.
Changing Parameters Using CCS Navigator
Before using CCS software applications to change your module’s parameter
settings, you must discover CCS Navigator the module. Discovery is the
processes by which your software finds, and then connects to your module.
Discovering a Module Using Navigator
To discover your module, your Navigator software must be in Build mode.
1. If the Discovery pane is not open, select Tools > Discovery in the main
menu.
A Discovery pane opens, most likely in the bottom left corner of the screen.
2. Click Options, and then click Add.
20APM6800+/APM6801+ Installation and Operation Manual
3. Enter the IP address of the frame that contains your module, the frame that
contains your ICE6800
+ module, or the frame that contains a 6800+ETH
module that provides access to your module.
4. Click OK, and then OK again to close the Discovery Options dialog box.
5. Click Start.
Navigator runs a discovery.
6. When your discovery is complete, Discovery Completed is displayed in
the Discovery pane. To continue, click Save to save the contents of your
discovery to the Discovery folder of the Navigation pane.
You can now switch to Control mode by selecting Operational Mode >
Control from the main menu. Double-click the module’s name in the
Navigation pane. The Control dialog box opens displaying the module’s
controls.
Changing Parameter Settings Using Card-Edge Controls
Use the module’s rotary and navigation switches to change your
APM6800+/APM6801+ parameter settings at the card edge.
1. Rotate the hex switch (mode select rotary switch) to “0.”
2. Once the hex switch is set to “0,” toggle the navigation switch up or down
to select a bank.
View the four control LEDs next to the navigation toggle switch to see
which bank is currently selected. (See
Table 3-1.)
See “Parameters, LEDs, and Alarms” on page 27 to view the various banks,
hex switch positions, and corresponding parameter options and values.
3. Rotate the hex switch to the parameter number (1 to 9) or letter (A to F) of
4. Toggle the navigation switch to select and set the value of the chosen

parameter.
•Rotate the hex switch to another parameter number/letter in the current
bank, and then repeat step 4.
•Rotate the hex switch to “0” again to select a different bank, and then
repeat steps 3 and 4.
For best results, use the available 6800+ software control options
(serial/local or Ethernet/remote) to help view, set, and confirm parameter
values.
Recalling Default Parameter Settings
You can use the module’s Factory Recall parameter to return all of the
module’s parameters to factory default settings. In the control parameter list
(see “Parameters, LEDs, and Alarms” on page 27), each factory default setting
appears in bold.
To return this module to its default settings, make the following selections:
You can see the current software and hardware versions of the
APM6800+/APM6801+ module. In Navigator, right-click the name of the
module in the Navigator Window, and then select Configuration. A dialog box
appears with the version information.
In addition, you can view the software and hardware versions in CSS-enabled
control panels.
Selecting the Module Locking Source
By using the Lock Source Select parameter, the module can be locked to any of
the following lock sources:
•Genlock
•DARS
•Dolby Decoder Source (for APM6800-D1+D/APM6801-D1+D, this is
Input
AES 1–8)
•Dolby Encoder Ch 1 Source (for APM6800-D2+D/APM6801-D2+D and
APM6800-D3+D/APM6801-D3+D, this is Input AES 1–8)
The Lock Source status parameter reports the locking source of the module.
When the module locks to either Genlock or DARS, it attempts to use DARS
for AES 11 compliance first. If DARS is not present, the module then attempts
to use the reference video for AES 11 compliance if the reference video frame
rate is either 25 Hz or 50 Hz.
Chapter 3: Configuration and Operation
Audio Test Tones
When the module locks to AES 1–8, the module uses the same AES input signal
for AES 11 compliance at the output. In this case, the DARS signal is not used,
even if it is present. If DARS or reference video needs to be used for AES 11
compliance, use either Genlock or DARS as the locking source for the module.

Clearing External Metadata
When you apply external metadata to the APM6800-D2+D/APM6801-D2+D
or the APM6800-D3+D/APM6801-D3+D, the metadata properties persist even
after you remove the external metadata from the module. Performing a Factory
Recall of the user settings does not clear the metadata properties that were
received when external metadata was present. After you remove the external
metadata, you must restart the module to clear the metadata properties.
Audio Synchronization
The APM6800+/APM6801+ modules provide the capability to synchronize
audio with a companion video frame synchronizer by using the Data I/O
connection. To enable the audio synchronizer, set the Audio Track Video
parameter to Yes. The Data I/O status of the upstream video frame synchronizer
will be reported in the Input > Data I/O menu.
Do not use the audio synchronization feature with the
APM6800-D1+D/APM6801-D1+D module. It can corrupt the incoming
Dolby E or AC3 signal.
24APM6800+/APM6801+ Installation and Operation Manual
Use of the audio synchronization feature will effect the maximum available
audio delay to any of the incoming AES signals. When the audio synchronizer
(Audio Track Video parameter) is set to No, the total available audio delay to
any of these signals is 2.5 seconds. When the audio synchronizer is set to Yes,
the total available audio delay is the result of 2.64 seconds minus the Data I/O Video Delay reported in the Input > Data I/O menu, up to a maximum of 2.5
seconds.
For example: if Audio Track V ideo is set to Yes and the Data I/O Video Delay
reports 1500 ms, the maximum available audio delay will be 1140 ms.

Firmware upgrades for the APM6800+/APM6801+ can also provide firmware
upgrades for the Neural audio processing submodule. In the event firmware for
the submodule is upgraded, the module will take approximately 2.5 minutes to
fully start up while new firmware is loaded. During this time the card-edge
LEDs will flash back and forth. Once this time has elapsed the module will
become controllable. Subsequent module start-ups will resume to the normal 8
seconds.
The default settings for each module represent typical setups and
configurations for that type of Neural processing device.
Audio Delay with Neural Modules
In some cases, Neural audio processing adds propagation delays to a signal. For
a module-by-module list of the delays, see Table 5-9 on page 76.
You can adjust the Neural Audio Out Delay parameter for each audio output
channel. These parameters are located at Processing > Neural > Delay.
DTS Neural® Surround™ UpMix
The DTS Neural Surround UpMix renders any two channel audio source
(stereo, matrix encoded stereo, LtRt, or DTS Neural Surround LwRw) as
surround sound. The DTS Neural Surround UpMix can simultaneously position
individual elements within the surround field, creating high levels of image
stability and granularity.
The UpMix technology avoids taking “artistic license” with content by placing
audio exactly where it would be heard in a professional LEDE (Live End Dead
End) listening environment. For example, mono or pan-pot stereo will image in
front of the listener, whereas stereo containing depth information will surround
the listener .
You can use the DTS Neural Surround UpMix as a stand-alone unit to monitor
stereo production, or you can use it in tandem with the DTS Neural Surround
DownMix as a complete 5.1 transport solution.
Figure A-1 below shows an UpMix taking a two-channel audio source (stereo,
matrix encoded stereo, LtRt or DTS Neural Surround LwRw) and rendering a
5.1 multi-channel mix.
80APM6800+/APM6801+ Installation and Operation Manual
All of the UpMix parameters are located in Table 4-8 on page 59. Neural
UpMix parameters appear in APM6801UM+D and APM6801UM+LC+D
modules.
APM6801DM+D DTS Neural® Surround™ DownMix
The DTS Neural Surround DownMix enables 5.1 surround sound to be
transported through any stereo infrastructure. The downmix process is based
upon the principle that both natural stereo and 5.1 content are t wo-dimensional ;
both contain width and depth spatial attributes.
The DTS Neural Surround DownMix can represent six channels of discreet
audio sources in a stereo downmix by transforming the sources into pure
intensity and coherence encoding. By correcting overlaps of the signal sources
in intensity, time, coherence, polarity, and phase before the six channels are
combined, the DTS Neural Surround DownMix accounts for the problems
suffered in traditional matrix encode systems—such as comb filtering, spatial
location distortion, etc.
The proprietary Neural Audio “watermark process” faithfully reproduces
surround information when it is rendered by the DTS Neural Surround UpMix
or any LtRt system. In brief, the DTS Neural Surround DownMix produces a
stereo downmix that accurately represents the original content whether
monitored in mono, stereo, matrix or DTS Neural 5.1 Surround Sound.
Figure A-2 shows a DownMix taking a multi-channel audio source. The
downmix creates two-channel audio source using the Neural Audio approach of
embedding a watermark signal within the stereo audio signal patch. The
watermark signal contains spatial and steering positioning information. The
resulting stereo audio signal is also known as LwRw.
APM6800+/APM6801+ Installation and Operation Manual81
All of the DownMix parameters are located in Table 4-9 on page 60. DownMix
parameters appear in the APM6801DM+D, APM6801DM+LC+D, and
APM6801LC+DM+D modules.
APM6801MM+D DTS Neural® Surround™ MultiMerge
The DTS Neural Surround MultiMerge enables broadcasters to transition from
stereo to 5.1 surround sound, providing viewers with a 24/7 surround sound
experience. With MultiMerge inline, 5.1 original content is passed unaf fected to
the viewer while original stereo content is upmixed to a 5.1 surround sound
image. This provides the viewer with a consistent surround experience.
The transition between 5.1 and stereo occurs seamlessly without the need of
operator intervention. By offering a 24/7 5.1 signal, AC3 metadata does not
transition between 2/0 and 3/2 mode. This prevents audio clicks, pops, and
dropouts. The process also avoids taking “artistic license” with content by
placing audio exactly where it would be heard in a professional LEDE (Live
End Dead End) listening environment. For example, mono or pan-pot stereo
will image in front of the listener, whereas stereo containing depth information,
or LtRt encoding, will surround the listener.
You can use the MultiMerge in combination with the DTS Neural Surround
DownMix device to pass 5.1 through stereo-only facilities and therefore
eliminate the need for costly master control upgrades.
Figure A-3 shows how the MultiMerge takes a two-channel audio source
(stereo, matrix encoded stereo, LtRt or DTS Neural Surround LwRw) and
render a 5.1 multi-channel mix; in combination with taking original
multi-channel content and creating a stereo downmixed signal, depending on
the input configuration and content source used.
82APM6800+/APM6801+ Installation and Operation Manual
•Auto determines if the content is stereo (2.0 ) or surround (5.1), and adapts
to the correct UpMix/Passthrough mode for consistent 5.1 output).
When in Auto, the Detect Threshold parameter controls the noise floor
level for the detection. If any content is above this threshold on the surround
channel inputs 3-6 (C, LFE, Ls, Rs), the input will be considered surround
and MultiMerge will be in passthrough mode.
•Passthrough forces MultiMerge to always pass through 5.1 content to the
5.1 outputs untouched, while creating a downmix for the stereo output.
•UpMix forces MultiMerge to always upmix stereo content on both of the
Left/Right 5.1 inputs and the Aux 2.0 inputs (C, LFE, Ls, and Rs content is
still passed through).
Input Select Mode offers eight options:
•Mix mixes the auxiliary 2.0 inputs into the multichannel 5.1 inputs.
•Multi always uses the multichannel 5.1 inputs.
•Stereo always uses the stereo L/R pair from the multichannel inputs.
•Aux always uses the auxiliary 2.0 inputs.
•Multi Detect uses multichannel 5.1 inputs if they are active. If not, the
auxiliary 2.0 inputs are used.
•Stereo Detect uses the stereo L/R pair from the multichannel 5.1 inputs if
they are active. If not, the auxiliary 2.0 inputs are used.
•Aux Detect uses the auxiliary 2.0 inputs if they are active. If not, the
multichannel 5.1 inputs are used.
APM6800+/APM6801+ Installation and Operation Manual83
•Multi Aux Stereo uses multichannel inputs if they are active, or uses the
auxiliary inputs if they are active. If neither of those is active, it uses the
stereo L/R pair from the multichannel inputs.
All of the Multimerge parameters are located in Table 4-10 on page 61.
MultiMerge parameters appear in the APM6801MM+D and
APM6801MM+LC+D products.
Neural Loudness Control
APM6801+ Neural Loudness Control options manage loudness levels within a
specific desired volume range. Advanced psychoacoustic and signal processing
techniques detect and regulate the perceived loudness of stereo and 5.1 sources,
for example to maintain audio perceived loudness between programming and

Neural Audio’s perceptual loudness measurement tool treats each audio channel
(L, R, C, LFE, Ls, and/or Rs) as a separate mono channel. The tool accounts for
spectral and density differences and temporal overlaps in modelling how the
human ear perceives the loudness of the audio content. DTS Neural loudness
measurement accommodates both stereo and multi-channel audio equally well.
After measurement, DTS Neural Loudness Control applies gain or attenuation
to achieve the target loudness level (Dial Norm) while preserving the spectral
balance of the original signal. It adapts the frequency response of the low and
high frequencies to compensate for level differences within the original signal.
You can use DTS Neural Loudness Control in the following roles:
•Protection—only affecting content that falls aggressively outside the
desired target
•Management—tightly controlling loudness to guarantee intelligibility
without the distracting side effects of traditional volume management
solutions
Because of the single function nature of APM6801+ modules, default settings
provide an optimal configuration for the normal audio situation.
Neural Loudness Control parameters appear in the APM6801LC+D,
APM6801LC+6+2+D, APM6801LC+8+D, APM6801LC+DM+D,
APM6801UM+LC+D, APM6801DM+LC+D, and APM6801MM+LC+D.
The parameters are listed in Table 4-11 on page 62.

Neural Loudness Control is available on its own, and in various combinatiosn
with other audio processing options. The following Neural Loudness Contro l
options are available on APM6801+:
•APM6801LC+D Neural Loudness Control for 2.0 or 5.1
This module receives 2.0 or 5.1 input, and outputs audio in the same format.
It can do one or the other, not both.

•APM6801LC+6+2+D Neural Loudness Control for 2.0 and 5.1
The Neural Loudness Control 6+2 configuration is used when a 5.1
multichannel or surround sound mix is accompanied by an independent
stereo mix. It uses the same advanced psychoacoustic and signal processing
techniques to accurately detect and regulate the perceived loudness of stereo
and 5.1 sources. Common uses are for network programming with SAP,
LtRt or Descriptive Video programming.

•APM6801LC+8+D Neural Loudness Control for 4 x 2.0
This module provides Neural Loudness Control for four separate channels
of 2.0 Program Audio, balancing each of the four inputs separately. Neural
Loudness Control supports any stereo format (2.0, LtRt, LoRo, LwRw).
