echo cancellation while the SR-series products do not include acoustic echo
cancellation. The processing capabilities will be described in the following
sections.
OBAM™ - One Big Audio Matrix
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
1
. This
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:
