Speaker Feeds - Adjusting Upmix / Downmix Rules
The box on the right hand side of the screen shows which speakers will be fed by which signals in the different monitor configurations. For
example, in the previous diagram, the left signal is chosen in the select signal column and in the speaker feed section you can see the
speakers which will be fed by this signal in the different monitor configurations.
The selected left signal for the stereo source feeds the left speaker in all cases but also feeds the centre speaker in 5.1, LCRS and LCR
speaker configurations. The settings can be changed by pressing the ON/OFF buttons.
Pressing Default will reset the Speaker Feeds for this signal to their original settings. The default configurations provide settings recom-
mended by Dolby for the purposes of checking different mix formats on various speaker sets. E.g.. A surround mix on a stereo speaker
set.
Pressing Default All will reset the Speaker Feeds for all the signals in this speaker set to their original settings.
Pressing Adjust Levels will put the upmix/downmix level indicators into edit mode and you can then adjust the levels individually to suit
your own application using the console Touch Turn control.
A Presets button opens another panel where user defined Upmix/Downmix rules can be stored and recalled.
The same Presets can also be accessed from the Buss to Buss Upmix/Downmix panels.
Source Switch Toggles
The Toggle switches one, two and three can be configured to change monitor sources. When pressed, they can select a specific source
or set of sources. If you wish to make A/B comparisons between two different sets of sources the buttons can toggle on repeated presses.
(The first press for one set of sources and the second press for another).
To achieve this you must put Macro commands into the nodes which represent the eight different Speaker Sources.
To enter Macro commands touch the Node of the required source and then touch the relevant Select Toggle Command in the box at the
bottom of the panel. There are 5 different commands:
ON - The source will be switched on at each press of the output switch.
OFF - The source will be switched off at each press of the output switch.
TOGGLE ON - The source will be switched on at the first press of the output switch and off at the second press.
TOGGLE OFF - The source will be switched off at the first press of the output switch and on at the second press.
NONE - The source will not be affected by the action of the output switch. This is different to the OFF setting as that will specifically turn
the source off when the output switch is pressed.
