• Loudness Setup Menu Overview
– Source Selection
• ‘Fixed’ mode – Audio measured
is defined by manual channel
selection
• ‘Follow’ mode – Audio measured
is defined by ‘Scroll’ selection
• ‘Dolby’ mode – Audio measured
is Dolby encoded channel
defined
Source Selection

13. Loudness Setup Menu Overview
• ‘Target’ sets
desired loudness
target value
between range -13
and -34 LU
• Dialnorm is
automatically
selected when
‘Source’ is set to
Dolby
Target Value

14. Loudness Setup Menu Overview
• Loudness measurement is
activated and may be paused
and reset as required
• Start measuring loudness from
the targeted channels via the
‘button’ or from a GPI closure
• ‘Stop’ pauses the
measurement. Toggle this
button or use a GPI to control
• ‘Reset’ discards any previously
measured values or history and
may be activated via the
button or GPI
Start/Stop/Reset

15. Loudness Setup Menu Overview
• Display Modes define
measurement integration
settings
• ‘3 Sec’ activates a 3 second
sliding window (sample at
400 ms)
• ‘Integrated’ mode measures
loudness across the entire
duration of the audio
programme (as defined by
start/stop/reset)
• ‘Gated’ is similar to
Integrated but discards
audio 10dB below target
level
Display Modes

16. Loudness Setup Menu Overview
• ‘Limit’ sets a threshold
value above Target at
which the LU reading ‘red
lines’ within a range 0 to
+6LU
• An ‘over limit’ reading
activates an output GPI
trigger
Limit Threshold

17. Loudness Histogram
• To access Histogram
from top level, press
‘Shortcut’ button
• Then press
‘Loudness’

18. Loudness Histogram
• Loudness Histogram provides
an instant overview of channel
loudness behaviour
• The time constant can be
adjusted to display 2, 7, 15,
30 and 60 minute history
• The ‘Loudness History’ button
is used to access the
Loudness Setup Menu
• The ‘Display’ button changes
the time constant of the
graphical view between 3
second, Integral and Gated
modes retrospectively

19. Assign Matrix - Overview
• The Assign Matrix is designed for use in applications where audio
is delivered or transported in ‘non standard’ channel orders and
where multiple commentary or language soundtracks are present
within a common embedded video signal
• Assign Matrix functionality is based around a 16 into 6 user
configurable tool which exclusively routes input audio channels to
monitoring busses defined as Left, Right, Centre, LFE, Left
Surround and Right Surround
• The key to use of the Assign Matrix is the ability to save complex
setups as User Presets for instant recall

20. Assign Matrix
• The Assign Matrix can be
accessed from the Main Menu
• Any of 16 input channels can
be routed to the 6 output
busses
• As shown in this typical
example; Channel 3,4, 5 and
6 are clean surround
channels, Centre (dialogue)
is routed from channel 16.
LFE is ‘Off’
• Press ‘Active’ to turn on the
Assign Matrix

21. Assign Matrix – Bargraph Views
• From the previous example –
The Left screen displays the
routing selections with a stereo
downmix activated
• From the previous example – The
Left screen displays the routing
selections with a stereo downmix
activated

22. Audio Delay
• The Audio Delay feature can be
accessed from the Setup Menu
• A delay between 1 and 250ms can
be applied to the audio output
busses
• The audio delay feature is not a
system default. It should be
applied as a User Preset as
required
• This feature is designed as a
means to compensate for video
processing and display latency
helping to ensure that lip sync is
maintained in production and
technical monitoring environments

23. Loudspeaker Muting
• Internal and External
Loudspeaker outputs can be
muted via the Setup 2 menu
• The LS mute feature is not a
system default. It should be
applied as a User Preset as
required
• By controlling external and
internal speaker outputs
independently, it is easy to use
PAM1-MK2 in applications where
internal speakers are operated for
general use and external full
range systems for more critical
listening – typically in Ingest or
QC Suites

24. Preset Standard Switching - Overview
• Preset Standard switching was introduced into PAM1-MK2
following a request to be able to configure a condition where
the audio monitoring unit automatically switches between
listening states depending on the input signal format
• PAM1-MK2 is capable of determining which audio channels to
monitor depending on whether the input video signal is SD or
HD, Dolby encoded or PCM audio
• This feature is aimed for use in monitoring applications where
outgoing video is switched between SD/stereo and
HD/surround sound, with or without Dolby encoding – the
operator no longer has to change audio selection manually as
PAM1-MK2 will automatically choose the correct audio channel
to monitor

25. Preset Standard Switching
• The Preset Standard Option can be
found within the Setup 2 menu
• There are 3 criteria that can be set
to define the system behaviour
when a signal changes
• Define a Hotkey Preset to be
selected automatically when
incoming video or audio is
SD/HD/PCM/Dolby
• Define a further Hotkey Preset to
be selected automatically when
incoming video or audio changes
• Typical conditions might exist
where one preset defaults to an
HD signal with Dolby E 5.1 and
another is SD stereo

26. Preset Standard Switching
• User Presets will automatically switch as
the input signal standard changes
• SD Only• HD Only
