GENERAL The Model SAP612 Source Assign Panel inde-
pendently assigns each oC24
TW
userstation strings) toany oneof six busses,orcommon
chaonels. All channels aqsigned to a common buss channel
can intercommunicate and exchange call signals. A typical
application is diagrammed in F~gure
power supplies (such as Models PS8 or PS15) may be
conveniently connected to the SAP612 to distribute power
the
to
a non-TW power source. Switchable 200-ohm line termina-
tions are built into the SAP612 for proper line termination
when using a non-TW power source. The SAP612 has
balanced, wnsformer isolated program inputs. Program 1
is permanently assigned to buss channel 5, and program 2
isperrnaoently assigned to buss chanrlel6.

POWER
NOTE
%W
Most
user stations are powered from channel one,
which is called a "wet" channel because it carries the DC
current in addition to thc channcl 1 audio. Channel
2
is a
"dry" channel because it carries audio only. It is impor-
tant to
remember this, since it can have an effect on chan-
nel rissignment later (see pxag~iplrs 2.2.1.2 and
2.2.1.3
below for specifics).

The power source must provide adequate filtering so as
not to introduce noise into the system. Connect the exter-
nal power supply ground lead to pin 1 of the CH
1-2
INPUTconnector; connect the positive lead to pin 2. Set
all
termination switches to the Internal (Switched-in) posi-
tion. In this application, buss one is used lo supply powcr
