1.11 Output Selector
The output-selector allows to connect the main- or the second-source to the Front-, Rear and Subwoofer speak-
er-attenuator, respectively. As an example of this programming the device is able to connect via software the
main-source to the back (rear) and the second-source to the front (see Figure 17). In addition to this stage allows
to setup different applications by IIC-Bus programming. In figure 18 to 20 three examples are given.
