SSA-424

Dual Digital Hybrid

Unspecified 

2.4.3 CLEAR-COM AUDIO CONNECTION

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.

2.4.4 OTHER 2-WIRE AUDIO CONNECTION

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:

Pin 2:

Pin 3:

No connection

Balanced Audio + Input/Output

Balanced Audio - Input/Output

There are two possible configurations for unbal-

anced connection:
