R3910 Datasheet, PDF (2/22 Pages) ON Semiconductor – Preconfigured DSP System

RHYTHM R3910
Other Key Features − R3910 also supports the following
features: FrontWave^® directional processing, built−in
feedback path measurement, cross fading between audio
paths for click−free program changes, 16−band graphic
equalizer, 8 generic biquad filters (configurable as
parametric or other filter types), programming speed
enhancements, optional peak clipping, flexible compression
adjustments, direct interfaces to analog or digital volume
control, rocker switch, direct audio input and telecoil.
R3910 also encompasses industry−leading security features
to avoid cloning and software piracy.
