DESCRIPTION
TSL Products' flagship Precision Audio Monitor series is arguably the most comprehensively enabled confidence monitoring system available today. The PAM2 MK2 is one of the first audio monitoring solutions to feature Dolby's CAT1100 module as an option for deciding Dolby audio formats. Equally adept in stereo, multichannel, multi-language or surround sound environments, both the PAM1 and PAM2 MK as seen in this video, provide the user with a highly sophisticated yet intuitive solution to the challenges presented by modern broadcast sound workflow. See our comprehensive training video on the capabilities of this piece of equipment. TSL Products' manufacture a range of Audio Monitoring products for music, TV and film broadcasting applications.

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
