PAM1 MK2 User Handbook Issue 1
In use, when monitoring modes are being setup and saved as a Preset and will be subject to
Preset Standard rules, the Pst Std selection must be made and saved as part of that preset or
presets.
Important:
For Preset Standard to work, the SD preset should be stored directly adjacent to the
HD preset at either a pair of User Preset locations or two Hotkey buttons. The SD button must
have first been pressed to recall said mode in order to activate automatic switching operation.
Application Example
: SDI 1 input is cabled across a TV Station transmission which switches
between SD and HD material. The SD signal always contains an embedded stereo audio
programme on Group 1 Pair 1: the HD signal comprises a Dolby E signal on pair 2 with an
encoded 5.1 programme. The operator wants to hear the stereo programme when an SD signal is
present and the Lt Rt Downmix decoded from the Dolby E signal when HD is present without
having to remember to switch between listening modes manually. Preset Standard Rules can be
used to configure two independent Hotkey Presets between which the PAM1 will automatically
switch as the input signal standard changes.
The images below show how the application example would appear in operation with the
Data
button active and SD Only and HD Only Preset Standard Rules applied to Hotkey Preset
buttons 1 and 2.
