Finally, as shown in Figure 1c, the Crossfade function is added by steering the
output current from VCA-B to the current-to-voltage converter of VCA-A. The
current outputs of both VCAs sum in this i-to-v converter and are output via the
Chan 1 Output. Jumper H6 selects whether the current output of VCA-B is sent
to the Chan 1 (i.e. crossfade) or Chan 2 output (other modes).
The astute reader will notice that Figure 1c and Figure 1 are the same. Thus, this
completes our tour through the THAT2162 DEMO BOARD signal topology.
Table 1 shows how to set the various jumpers on the PCB for the various operat-
ing modes.
