ELVIS Function Generator Configuration Switch (SW8)

The function generator configuration switch (SW8) controls signals con- necting to the left and right input signals of the audio interface. The SW8 switch is used when the board connects to the ELVIS station (see “ELVIS Interface” on page 1-12). Each channel must have only one signal selected at a time, as described in Table 2-11.
