The audio selection switch (SW15) connects the left channel of the In5 line,
connected to the AD1939’s ADC9 circuit, to either the single-ended RCA
connectors or the differential DB25 connector. By default, the switch is
set up to use the RCA connectors. The switch circuit is connected to
AD1939C (codec C). To use the standard, off the shelf DB25 connector
to XLR cables, change the switch to the differential setting; see Table 2-9.
