New NAU83G60 with KLIPPEL Controlled Sound

Intelligent Smart Amplifier with KCS

Our business partner, Nuvoton, will soon release the new NAU83G60. This stereo 2x30W smart amplifier boasts an integrated low latency Advanced Audio DSP that runs the KLIPPEL Controlled Sound (KCS) nonlinear adaptive speaker control algorithm. KCS provides highly accurate mechanical and thermal speaker protection while the nonlinear control system reduces harmonic and intermodulation distortion generated by speaker nonlinearities. Thanks to active DC compensation, the voice coil can be operated at its ideal rest position for maximum bass output. NAU83G60 voltage and current sensing enables continuous identification of speaker parameters. Hence, parameter variations caused by aging, production variances or climate changes can be compensated.

Traditional linear speaker protection algorithms tend to limit speaker performance at high amplitudes. However, NAU83G60 with KCS truly shines in this regard. Its unique feature set allows speakers to operate safely at their physical limits, enabling increased loudness and deeper bass with higher sound quality for consistent best-in-class performance.
