Following the connections in the previous figure, as an example of this linking
order and how the physical channels are numbered, consider the system of
three SoundStructure C16 devices shown in the following figure. In this exam-
ple the OBAM output of device A is connected to the OBAM input of device B
and the OBAM output of device B is connected to the OBAM input of device
C. While the individual devices have physical channel inputs ranging from 1
to 16 and physical outputs ranging from 1 to 16, when linked together, the
physical inputs and outputs of the overall system will both be numbered 1 to
48. These physical channel numbers of all the inputs and outputs will be
important because it will be used to create virtual channels, as will be dis-
cussed in the next section.

With the linking of devices as shown in the previous figure, the physical chan-
nels will be ordered as expected and shown in that figure and summarized in
the following table.
