SoundStructure Design Concepts
3 - 3
The physical input channels and the physical output channels will be
numbered from 1 to the maximum number of physical channels in a system.
As described below, this approach is an enhancement of how traditional audio
signals are labeled and how their signals are uniquely referenced.
Physical Channel Numbering On A Single SoundStructure Device
As described previously, in single-device SoundStructure installations (for
example using a single SoundStructure C16), the physical channel numbering
for the inputs and outputs corresponds to the numbering on the rear-panel of
the device, for example, physical input channel 3 corresponds to input 3 on the
SoundStructure C16 device and so on as illustrated in the following figure.
Physical Channel Numbering With Multiple SoundStructure Devices
When multiple SoundStructure devices are linked using OBAM to form a
multi-device SoundStructure system, instead of using a device identification
number, the physical channel numbering for both the inputs and the outputs
will range from 1 to the maximum number of inputs and outputs, respectively,
in the system. This is an extension of the single device setup where the physical
channel numbers for channels on the second device are the next numbers in
the sequence of inputs from the first device. For if there are two devices and
the first device is a SoundStructure C16, the first input on the second device
becomes physical input 17. This continuation of the sequence of numbers is
possible due to the design of the OBAM Link interface.
OBAM Link is the method for connecting multiple devices together as simply
as connecting the OBAM Link cable from one device to the next. The next
figure shows the location of the OBAM connections and the OBAM OUT and
OBAM IN connections on the rear-panel of a SoundStructure device. To help
verify when the OBAM Link is connected properly, there are status LEDs near
the outer edge of each connector that illuminate when the devices are linked
successfully.
