3. To connect each input channel to its corresponding output
channel, click and drag a line, representing a wire, between
the blue pin of the input channel and the green pin of the
output channel (see Figure 24). Input Channel 0 connects
to Output Channel 0 and Input Channel 1 connects to
Output Channel 1.

The default register settings in
match the hardware of the EVAL-ADAU1466Z, including the
signal routing between the ADAU1466
When these steps are complete, the basic signal flow is complete,
and the stereo analog input source passes directly through the
SigmaDSP and connects to the stereo analog output.
Add Volume Control
1. To add a volume control block, from the Volume Controls
> Adjustable Gain > Clickless HW Slew folder, click Single
Volume and drag it into the project space to the right of
the toolbox.

2. By default, the volume control block has one input and one
output. In other words, it is a single channel. To add another
channel, right-click in the empty white space of the Single-
Volume block, and then from the dropdown menu that
appears, select Grow Algorithm > 1. Gain (HW Slew) > 1
(see Figure 26).
3. To delete the existing yellow connection wires (that is, the
connections added in Step 3 of the Creating a Basic Signal
Flow section), click the connection wires + Delete.
SigmaStudio are configured to
