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
