RTS SSA-424 4-Wire to 2-Wire Converter with Auto Nulling
This dual digital hybrid interfaces two two-wire intercom lines to two four-wire lines, and also interfaces balanced and unbalanced two-wire lines. Unlike earlier analog hybrids, the SSA-424A features advanced digital signal processing to achieve automatic nulling of the two-wire lines.
In addition, 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. The SSA-424A features improved auto-nulling. In addition, there is a call light option board available.
Compatible two-wire intercom systems include RTS® Two-Wire Intercom, Telex® 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 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.
