OBAM™ - One Big Audio Matrix
echo cancellation. The processing capabilities will be described in the follow-
ing sections.
One of the significant advancements in the SoundStructure products is the
ability for multiple devices to be linked together and to be configured and
operated as one large system rather than as multiple individual devices
feature dramatically simplifies any installation where audio from more than
one device is required such as complicated sound reinforcement applications.
OBAM's 'one large system' approach provides many benefits including:
• It is easier to work with the system because all the input signals feed into
the single matrix and all the outputs are fed from the single matrix
