- 3. Front Panel Control Explained • Master Volume – Push to Cut/Dim • Scroll Encoder – Push/Hold and turn to select audio channels and Push/Select for menus • Data / Loudness Button – Toggle between Data / Loudness and Meter views Data button used for ‘Save’ when in menu modes • Video Button– Toggle between Video and Meter views Video button used as ‘Back’ when in menu modes
- 4. Front Panel Switch Mode Selection • By repeatedly pressing the ‘Home’ button
- 5. Saving User Presets • PAM2-MK2 features 24 user preset locations • Push and hold any Preset Hotkey to enter ‘User Save’ menu • Select a ‘User’ memory location • Clear any previous memory data and use the encoder to enter a name • Once complete, press ‘done’ and the preset will be saved to the selected location
- 6. 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
- 7. 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 • Audio Delay – detail to follow
- 8. 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
- 9. 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
- 10. 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
- 11. Loudness Measurement – Left Screen Overview ‘Measured Dynamic Value’ ‘Target Value’ ‘Measured Value’ Moving Cursor ‘Target Value’ Reference Line ‘Channel Under Test’ Measured Audio
- 12. Loudness Setup Menu Overview – Source Selection • 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
- 13. 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
- 14. 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
- 15. 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
- 16. 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
- 17. Loudness Histogram • To access Histogram from top level, press ‘Data’ button • Then press ‘Loud’
- 18. 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
- 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 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
- 24. 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
- 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 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
- 26. Preset Standard Switching • User Presets will automatically switch as the input signal standard changes •• SHD Onnllyy
