NAU83G60 Smart Amplifier

NAU83G60 is a stereo 2x30W smart amplifier with integrated low latency Advanced Audio DSP running the KCS (KLIPPEL Controlled Sound) 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 enable continuous identification of speaker parameters. Hence, parameter variations caused by aging, production variances, or climate changes can be compensated.

While conventional linear speaker protection algorithms cripple where it matters the most – at high amplitudes – this is where NAU83G60 with KCS truly shines. Its unique feature-set allows operating speakers safely at their physical limits. This enables increased loudness and deeper bass with higher sound quality for consistent best-in-class performance.
