SoundStructure Product Family
There are two product lines in the SoundStructure product family - the
SoundStructure C-series designed for audio conferencing applications (the
“C” stands for conferencing) and the SoundStructure SR-series designed for
commercial sound applications (the “SR” stands for sound reinforcement).
While these two product families share a common design philosophy they
have audio processing capabilities that are designed for their respective
applications. As described in detail below, the C-series of products include
acoustic echo cancellation on all inputs and are designed for audio and video
conferencing applications. The SR-series of products do not include acoustic
echo cancellation and are designed for dedicated sound reinforcement, live
sound, broadcast and other commercial sound applications that do not require
acoustic echo cancellation processing.
SoundStructure Architecture Overview
This section defines the common architectural features of the SoundStructure
products and then details the specific processing for both the C-series and
SR-series products. Details on how to configure the devices are presented in
Chapters 3 - 5.
All SoundStructure products have been designed with the flexibility of an
open architecture and the ease of design and installation of a fixed architecture
system. The resulting solution has tremendous flexibility in how signals are
processed while simultaneously making it easy to achieve exceptional system
performance.
The SoundStructure processing includes input processing that is available on
all the inputs, output processing that is available on all the outputs, submix
processing that is available on all the submix signals, telephony processing
that is available on all the optional telephony interfaces, and an audio matrix
that connects this processing together. The high-level architecture is shown in
