3.3 Factory Preset Filter Descriptions
1CH MODE:
Notice that in 1CH MODE, only the LEFT (PRI) input gets processed. This signal is first fed through
the Limiter, which helps prevent the signal from distorting on overload.
The signal then enters the first stage 1CH Adaptive filter, which is configured as follows:
Table 2: 1CH MODE First Stage Factory Presets
Parameter Preset Value
Filter Size 1024 taps
Prediction Span Delay 2 samples
Adapt Rate 8
Adapt Mode Auto
Output Residue
Algorithm LMS
Crash Detect Enabled
After the first stage of filtering, the signal enters the second stage 1CH Adaptive filter, which is
configured as follows:
