NSP-6241A amplifier chip

for advanced multi-channel full digital amplifier
   systems. NSP-6241A includes essential preprocessor features like full channel mixer, volume and tone
   control, dynamic range compression and general purpose biquad filter blocks. By combined use of built-in
   mixer and biquad filters, additional processing like Dolby bass management, loudness control and preset
   parametric equalizers can be implemented. Neofidelitys patent filed functional block called SFACS
   (Sampling Frequency Adaptive Coefficient Scaling) and world-unique floating point operation scheme
   eliminate audio performance degradation problems in conventional digital amplifier system.
   It has two channels of auxiliary digital audio input and two channels of auxiliary digital audio output
   interface. It also provides high quality two channel amplified headphone outputs that can directly drive
   headphone at power level of 38mW.
   NSP-6241A adopts 12x over-sampling and best for out of band noise reduction for sensitive system
   design.
