and the preset will be saved to
the selected location
Main Menu
• Accessed via the encoder
• Select from six options
• ‘Setup’ for engineering and
‘set and forget’ functions
• ‘Input’ usually not required if
preset defaults are maintained
• ‘Monitor’ modes can be
replicated via front panel using
‘Home’ button
Setup 1 Menu – Key Features
• Meter scale, reference,
colours, peak level and hold
• External Monitor On/Off
• System Mute defeat mode
• USB device save and load

Setup 2 Menu – Key Features
• User and Hotkey Preset Lock
• Screen Brightness Levels
• Auxiliary Mixer – detail to
follow
• Preset Standard Switching –
detail to follow
• External / Internal
Loudspeaker Mute – detail to
follow
Aux Input Mixer
• Ideal for mixing Comms
audio with monitored SDI
• Aux Mixer is accessed via
Setup Menu 2
• Select input source
analogue or AES
• Select whether source is
mono or stereo
• Adjust gain as required
• Gain can be adjusted
from the Input Menu
Split Mono Selection
• Split Mono allows the user
to listen to a left and right
signal from non-paired
audio channels
• Use ‘Scroll’ to select the first
mono signal
• Whilst the LED adjacent to
the encoder is flashing scroll
the encoder (without
pushing) to the second
mono channel

Loudness Setup Menu Overview – Source Selection
• Loudness Setup Menu Overview
– Source Selection
• ‘Fixed’ mode – Audio measured

selection
• ‘Follow’ mode – Audio measured
is defined by ‘Scroll’ selection
• ‘Dolby’ mode – Audio measured

Loudness Setup Menu Overview – Target Value
• ‘Target’ sets
desired loudness
target value
between range -13
and -34 LU
• Dialnorm is
automatically
selected when
‘Source’ is set to
Dolby
Loudness Setup Menu Overview –Start/Stop/Reset
• 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
Loudness Setup Menu Overview – Display Modes
• 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
Loudness Setup Menu Overview – Limit Threshold
• ‘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
Loudness Histogram
• To access Histogram from top level, press ‘Data’ button
• Then press ‘Loud’
Loudness Histogram
• Loudness Histogram provides an instant overview of channel loudness behaviour
• The time constant can be adjusted to display 2, 10, 20, 40 or 80 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
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
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
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
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
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 PAM2-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
Preset Standard Switching - Overview
• Preset Standard switching was introduced into PAM2-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
• PAM2-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 PAM2-MK2 will automatically choose the correct audio channel to monitor
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 User Preset to be selected automatically when incoming video or audio is SD/HD/PCM/Dolby
• Define a further User 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
Preset Standard Switching
• User Presets will automatically switch as the input signal standard changes
• SD Only• HD Only
