data and use the encoder to

enter a name

• Once complete, press ‘done’

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

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 – Target Value

• ‘Target’ sets

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
