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, Telex Audiocom, and Clear-Com. Compatible with Four-Wire inter-
com systems. An internal call signal option board is also available for the SSA-424A. This option board provides call signal
compatibility 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.
