4 The card edge display
The auto-configuration process, performed when a TANDEM-110 is first powered up,
normally returns the card to the state it was when powered down. If the audio option
piggyback cards have been changed, the following default settings are normally selected:
Audio group source and destinations (default: group1)
Audio gains (unity gain/100%)
On-card audio routing (default: dual embedder, dual de-embedder or mixed
embedder/de-embedder – option card dependent)
Delay (default: none)
Phase inversion (default: normal)
The TANDEM-110 card can be controlled or configured once this 16-second initialisation
procedure is complete.
The front edge of the card provides power rail monitoring, menu selection, an analogue
audio monitoring output, rotary set-up controls and a ten-digit visual status display.
In general the Menu switch is used to select one of four main menus, whilst the SEL
rotary hex switch selects sub-menus or internal variables. The ADJ shaft encoder is used
to assign values to variables (such as audio delay or routing assignments).
Changes made using the shaft encoder are generally not implemented immediately. The
display will normally flash alternately between bright and dim to indicate that the
displayed value may no longer be current when the ADJ shaft encoder is turned. To save
a new value simply toggle MENU switch 1 down and then up again.
If a setting is adjusted by mistake, changing the menu (piano MENU or SEL switches)
will discard the unwanted setting.
