3 - 18
When multiple devices are OBAM linked as shown in the next figure, the logic
inputs and outputs on the first device will be numbered 1 - 22 and the logic
inputs and outputs on the second device (device B) will be numbered 23 - 44,
and so on. The analog gain inputs will be numbered 1 and 2 on the first device,
3 and 4 on the second device, and so on.

Due to the one large system design philosophy, logic input pins on any device
can be used to control features on any SoundStructure device - not just provide
control on the device the logic inputs are on. Similarly logic outputs can be
used to provide status on signals on any SoundStructure device - not just
status on a physical channel on that particular device.
