An important feature is the Dynamic Damping Control (DDC) system that completely eliminates the influence of (in cinema, often very long) speaker cables. The result is a highly accurate bass and mid response, without the need for using high impedance speakers. Through the tamper-free internally accessible EFN circuit slots, extra signal processing functions can be added to the SSA amplifiers. The EFN-DP modules consist of three functions, all operating at the same time: clip/excursion protection; dedicated filtering; and power optimizing.
With the EFN-DP modules, all SA cinema systems deliver maximum output with optimum sound quality without the risk of mechanical damage. In order to minimize installation time and rack cabling, the SSA amplifiers feature a 15-pin D-connector. With this connection, all signal wiring to and from the monitor is carried out simply by connecting one D-connector cable (standard type) between amp and monitor. This Data-port is completely compatible with existing D-pin connected monitors.
