Button−per−source keys (programmable overrides)
Category/
Number keys
To select an input:
— press one of the 24 button−per−source (Override) keys on the left side of the panel, or
— press a category (e.g., “VTR”) and unit number combination, then press TAKE, or
— use the UP and DOWN arrows to scroll through all sources, then press TAKE, or
— press a category key and use UP/DOWN to scroll through the possible category entries, then press TAKE.
On a valid entry, the defined eight character mnemonic will be displayed in the Preset window.
When using the UP/DOWN arrows, scrolling past the end of the list will wrap around to the other end.
The newly selected source will be shown in the Current window. If an Override button was used to select the source (or if
an Override button corresponds to the selected source) the button will illuminate “high” green. However, the button will not
illuminate if the first level assigned to the panel on the Override set table has been set to “No” switching. Nor will it illuminate
unless all levels assigned to the button are switched.
If entry of a password is requested, please see Passwords on page 6−75.
Selecting a Source with PRESET On
With PRESET on, you can select an Override key(s) and check the source name(s) before pressing TAKE. The name of the
selected input will be previewed in the Preset window.
Scrolling Through Override Pages
Although the CP 3824 has only 24 Override keys, up to 360 inputs can be assigned, i.e., 15 groups (“pages”) of 24 inputs each.
To scroll to other pages, press PAGE, then UP or DOWN, TAKE. Pressing both UP and DOWN simultaneously will reset
to page 1.
The Override keys can be programmed using the panel itself (see page 6−85) or from the file server (see page 5−96).
