NSP-6241B amplifier chip

NeoFidelitys 6ch full digital audio amplifier processor NSP-6241B is a core DSP controller IC especially
   designed for advanced multi-channel full digital amplifier systems.
   NSP-6241B 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.
