DESCRIPTION
ON Semiconductor’s RHYTHM t SB3231 hybrid is a trimmer−configurable DSP system based on a four−channel compression circuit featuring Adaptive Feedback Cancellation, Adaptive Noise Reduction, and directional processing. Based on a phase cancellation method, Rhythm SB3231’s Adaptive Feedback Reduction algorithm provides added stable gain to enable extra gain and user comfort. It features rapid adjustment for dynamic feedback situations and resistance to tonal inputs. Rhythm SB3231’s Adaptive Noise Reduction monitors noise levels independently in 64 individual bands and employs advanced psychoacoustic models to provide user comfort. In addition to these adaptive algorithms, Rhythm SB3231 also supports the following features: up to four channel WDRC, low−distortion compression limiting, cross fading between audio paths for click−free memory changes, eight−band graphic equalizer, eight configurable generic biquad filters, programming speed enhancements, in−channel squelch to att...
