1 Use standard Clear-Com 3-pin cables. Connect
one Clear-Com party line to the J1A connector
on the back of the SSA-424 (System A). Con-
nect a separate Clear-Com party line to the J1B
connector (System B).
The SSA-424 features internal CD isolation.
You can therefore connect the SSA-424 to
powered Clear-Com cables, and it will not
draw any power from the Clear-Com system.
2 On the SSA-424 front panel, set the System A
and System B 2W CHAN SEL switches to
position 2.
If the System A or System B hybrid will not
be used, set its 2W CHAN SEL switch to
either OFF position.

1 Use the J1A connector on the back of the SSA-
424 to connect one 2-wire line to the System A
hybrid. Use the J1B connector to connect a
second 2-wire line to the System B hybrid. The
pin configuration for the J1A and J1B connectors
depends on whether you are connecting a
balanced or unbalanced 2-wire line:
Balanced Configuration
Pin 1:
No connection
Pin 2:
Balanced Audio + Input/Output
Pin 3:
Balanced Audio - Input/Output
There are two possible configurations for unbal-
anced connection:
Unbalanced Configuraton 1
Pin 1:
Audio Common
Pin 2:
Audio + Input/Output
Pin 3:
No connection
Unbalanced Configuration 2
Pin 1:
Audio Common
Pin 2:
No connection
Pin 3:
Audio + Input/Output
2 On the SSA-424 front panel, set the CHAN SEL
switches as follows:
•
Balanced Configuration: set the CHAN SEL
switches to the BAL position
•
Unbalanced Configuration 1: set the CHAN
SEL switches to position 1.
•
Unbalanced Configuration 2: set the CHAN
SEL switches to position 2.
If the System A or System B hybrid will not
be used, set its 2W CHAN SEL switch to
