● No limitations on how signals from multiple devices are used together, which is beneficial for A/V
designers.
● A transparent device linking scheme for all input signals that you share with all devices, which
simplifies the setup, configuration, and maintenance of large systems.
● Inputs and outputs you can view on one screen, which eliminates the need to configure multiple
devices by viewing multiple pages.
This one big system design approach is the result of the SoundStructure architectural design and the OBAM
high-speed bi-directional link interface between devices. With OBAM, you can link up to eight devices
together. If there are plug-in cards installed in multiple linked SoundStructure devices, the plug-in card
resources are available for routing to any output across the system. See the
Introducing SoundStructure Design Concepts
The one large system design philosophy means that the audio matrix of a system of SoundStructure devices
is the size of the total number of inputs and outputs of all the component devices that are linked together.
Since one SoundStructure C16 device has a 16x16 matrix, two C16 devices linked together create a 32x32
matrix and so forth.
The OBAM architecture is shown in the following figure where a C16 device is linked to a C12 device which
is linked to a C8 device. The resulting system has 36x36 inputs and 36 outputs (16+12+8 = 36). In addition
to all the inputs and outputs, the submixes of each device also feed the matrix allowing the designer to have
36 submix signals (not shown in the following figure), one for each input that can be used in the system.

The OBAM design architecture helps A/V designers to no longer be concerned with device linking because
multiple SoundStructure devices behave as, and are configured as, one large system.
