Dual Digital Hybrid

Unspecified 

1 Description and

Specifications

1.1 GENERAL DESCRIPTION

The SSA-424 Dual Digital Hybrid intervaces 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 2-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 easy and

accurate setup. With the SSA-424, all need for test

tones, nulling adjustments and ducking adjustments

have been eliminated.

Compatible 2-wire intercom systems include RTS™

TW, Audiocom®, and Clear-Com®. Compatible 4-

wire intercom systems include Telex’s ADAM™,

ADAM™CS, and Zeus™ Digital Matrix Intercom

Systems.

The SSA-424 is also available with optional call

signal interfacing. This option provides bidirectional

call signal compatibility between the 2-wire and 4-

wire intercom systems.

Peak Reading Level Meters: Quick and accurate

visual audio level adjustment. No extra setup equip-

ment or guesswork is required.

Direct ADAM/Zeus Audio Connection: Accepts

standard ADAM/Zeus DB9 or RJ11 keypanel cables.

Transformer Isolated: All audio inputs and outpus

are transformer isolated to prevent ground loops and

hum.

Call Signal Option: Detects call signals from any of

the compatible 2-wire intercom systems, and then

provides a +5VDC output to the 4-wire intercom

system. Accepts a contact closure input from the 4-

wire system and converts it to the call signal format

required by the 2-wire system. The SSA-424 can be

directly connected to an ADAM, ADAM CS, or Zeus

GPI (General Purpose Interface). GPI inputs can be

programmed to activate call signals and audio paths

to any of the available types of communication within

the 4-wire system, including intercom ports, camera

ISO circuits, IFB circuits, etc. GPI outputs can be set

up to place calls only from a specific keypanel within

the 4-wire system, or from any keypanel within the 4-

wire system that wishes to call the 2-wire system.

With features like digital signal processing, peak-

reading level meters and optional call signal interfac-

ing, the SSA-424 Dual Digital Hybrid assures ease

of setup and maximum transparency between

intercom systems.

1.2 GENERAL FEATURES

Two Independent Hybrids: Interface two separate

2-wire lines to two separate 4-wire lines.

Automatic Nulling: Digital hybrids eliminate all

nulling and ducking adjustments. Quick, trouble-free

setup. Puts an end to concerns about echo and

feedback when interfacing 2-wire lines.

Half-rack Wide, 1RU High: Two SSA-424’s fit into a

single rack space. Compatible with RTS TW rack

mount hardware. www.DataSheet.co.kr Can be mixed with other TW

equipment.

Universal Power Pack: Ready for worldwide use.

Automatically accepts any mains voltage from 100-

250 VAC, 50/60 Hz. Power pack equipped with

locking DIN connector for attachment to the SSA-

424.
