SB3231 - Pre-configured DSP

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.

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. The directional processing system utilizes a pair of microphones to create a fully customizable static polar pattern, such as bidirectional, cardiod, hyper.
  • cardiod and super.
  • cardiod. In addition to these adaptive algorithms, Rhythm SB3.
