The following table summarizes the number of inputs, outputs, and submixes supported within each type of
device. As shown in this table, each SoundStructure device has as many submixes as there are inputs to
the device.

A summary of the different types of processing in the C-series and SR-series products is shown in the
following table. As can be seen in this table, the difference between the products is that the C-series
products include acoustic echo cancellation while the SR-series products do not include acoustic echo
cancellation. The processing capabilities are described in the following sections.
Types of C-series and SR-series Product Processing
Product Processing
Input Processing
Up to 8th order highpass and lowpass
1st or 2nd order high shelf and low shelf
10-band parametric equalization
Acoustic echo cancellation, 20-22kHz 200 msec tail-time, monaural or stereo
Automatic gain control: +15 to -15dB
