Dual-Common (SB-D) Switch Configuration

The D configuration provides simultaneous connection of a bank of inputs to outputs (Figure 3). The input A can be connected to 1A of 1B or …(N/2)A. In this dual-common configuration, channel connections are stepped in pairs. The channel displayed is the current channel pair (A and B). The number of channel pairs is equal to one-half of the total number of channels (N).

Single Step Dual Common (SB-E) Switch Configuration

This non-blocking configuration allows any input to be connected to any output, but at the same time, adjacent inputs align with adjacent outputs (Figure 4). This configuration allows for single-step movement of paired input channels (A and B). The channel connection displayed is B path; A input channel is connected to B path minus one.
