Auto Table (AT)
A key assignment for listen keys only, when the corresponding talk key is assigned to
an IFB. Auto Table causes a listen key’s assignment to always be the same as the
Listen Source for whatever IFB is currently assigned to the talk key. (You define the
Listen Source in AZedit during IFB setup.) Auto Table is convenient in a broadcast
environment when a director needs 2-way communication with the IFB talent, AND
the IFB keys are frequently reassigned during the course of a program to talk to new
talent locations. Using AZedit, several IFBs can be set up in advance, and their Listen
Sources can also be defined during setup. Then every time an IFB talk key is reas-
signed on a keypanel, the Listen Source for each new IFB will automatically become
the listen key assignment for that key.
C
Crosspoint
The term “Crosspoint”, like the term “Matrix” is inherited from intercom systems, such
as the RTS™ CS9500, CS9600, and CS9700, that use a switching matrix to route
intercom audio. In those systems, the crosspoints are the actual switches that close
or open to connect or disconnect talk and listen paths. RTS™ ADAM, ADAM CS, and
Zeus Intercom Systems do not actually use crosspoint switches, but use a technique
called time division multiplexing (TDM), in which communications are routed as digital
packets. However, use of the term “crosspoint” persists since packet routing basically
accomplishes the same thing as conventional crosspoints: namely, connecting distinct
talkers and listeners. In this sense, a crosspoint can be thought of simply as a
communication link between any two points in the intercom system.
D
Destination
A destination is anything that a talk key talks to or a listen key listens to. A destination
can therefore be any port, party line, IFB, etc.
Dim
“Dim” occurs in two contexts in RTS™Digital Matrix Intercom Systems. First, the Dim
Table feature. Dim tables are used to correct a feedback problem that can occur
between two keypanels operating in close proximity that have keys assigned to talk /
listen to a common destination. Dim tables are setup in AZedit (search for keyword
“dim” in AZedit help). Once a dim table is setup, it can be assigned as a level 2 talk
assignment for those keys that are causing the feedback problem. For information
about how to make this assignment from a programmable keypanel, search for “Dim
Table” in the keypanel manual index. Second, the adjustable speaker dim available of
the KP-32 Keypanel. This causes the speaker or headphone volume to diminish by a
preset amount whenever a talk key is activated. This can help to prevent occasional
feeback between the speaker and microphone due to volume settings, microphone
placement, etc. For setup and usage, search for “Speaker Dim” in the keypanel
manual index.
