SSA-424A

Digital Interface/System-to-System Interface

The SSA-424A Dual Digital Hybrid interfaces two Two-Wire intercom lines to two Four-Wire lines. Unlike earlier analog hybrids,

the SSA-424A features advanced digital signal processing to achieve automatic nulling of the Two-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-424A, all need for test tones, nulling adjustments and ducking adjustments have been

eliminated.

Compatible Two-Wire intercom systems include RTS TW, Audiocom, and Clear-Com. Compatible with Four-Wire intercom

systems. An internal call signal option board is also available for the SSA-424A. This option board provides call signal compat-

ibility with any of the two-wire systems listed above. The output can also be directly connected to an ADAM, ADAM-CS, Cronus,

or ZEUS GPI port. No external circuitry is required. With features like digital signal processing, peak-reading level meters and

optional call signal interfacing, the SSA-424A Dual Digital Hybrid assures ease of setup and maximum transparency between

intercom systems.
