Figure 1 is a block diagram of the THAT2162 DEMO BOARD.
Admittedly, Figure 1 is a bit complex, so let's take it one step at a time.
Figure 1a shows the basic stereo signal flow of the circuit. The Chan 1 input goes
through one half of the THAT2162 VCA, a current-to-voltage buffer, and is output
by the THAT1606 OutSmarts™ balanced line driver. Chan 2 can take a similar
path to the Chan 2 output, or it can optionally carry the Chan 1 input via jumper
