Device Connections

Connecting to an SSA-424

General Description

The SSA-424 Dual Digital Hybrid interfaces two, 2-wire intercom lines to two, 4-wire intercom lines. Unlike earlier analog

hybrids, the SSA-424 features advanced digital signal processing to achieve automatic nulling of the 4-wire lines. Plus, each

hybrid features convenient peak-reading level meters to quickly match the levels between the lines that are being interfaced.

The result is an easy and accurate setup. With the SSA-424, all need for test tones, nulling adjustments, and ducking

adjustments have been eliminated.

4-Wire Audio Connections for ADAM, ADAM CS or Zeus

1. Use standard 9-pin or RJ-12 keypanel cables.

2. Connect from one port of your intercom system to J2A or J3A (System A connection) on the back of the SSA-424.

3. Connect from another port to J2B or J3B (System B connection).

4. on the SSA-424 front panel, set the 4W LEVEL REF SEL switches to the +8dB position.

Audio Connections for Other 4-Wire Communications Systems

1. Construct 9-pin or RJ-11 cables to connect from your 4-wire system to the SSA-424. To to the System A hybrid, use either

J2A or J3A; for the System B hybrid, use either J2B or J3B.

Pin Connections are as follows:

9-pin Connection

Connector Type (on SSA-424 end of cable): 9-pin male D-sub

Pin 1 No Connection

Pin 2 No Connection

Pin 3 No Connection

Pin 4 Balanced Audio + output (to 4-wire system)

Pin 5 Balanced Audio - output (to 4-wire system)

Pin 6 No Connection

Pin 7 Balanced Audio - input (from 4-wire system)

Pin 8 Balanced Audio + input (from 4-wire system)

Pin 9 No Connection

RJ-12 Connection

Connector Type (on SSA-424 end of cable)): RJ-12 plug

Pin1 No Connection

Pin 2 Balanced Audio + input (to 4-wire system)

Pin 3 Balanced Audio + output (to 4-wire system)

Pin 4 Balanced Audio - output (to 4-wire system)

Pin 5 Balanced Audio + output (to 4-wire system)

Pin 6 No Connection

2. On the SSA-424 front panel, set the 4W LEVEL REF SEL switches to the position which most closely matches the audio

input and output levels of your 4-wire system. If you don’t know the levels, select +4 dB. for the time being.
