Since the conception of Ncore in 2011, the technology has always been at the forefront of high-performance Class D amplification. Despite the performance advantage Ncore historically provided, the drive for improvement has always been present. It was this drive that led our research to Nilai, our latest and most advanced Class D technology.
Although Ncore amplification is still considered high-performance and far from obsolete, its ten years of service provided us with the opportunity to upgrade, bridging the gap to our latest Nilai technology.
Ncorex is a continuation of previous Ncore efforts, benefiting from Nilai research that enabled us to improve its loop filter while maintaining nearly all other favorable design concepts. Enhancing the loop filter allowed us to increase loop gain by 6dB in the top two octaves of the audio band, while adding some additional gain below that.
This gave us more leeway to optimize various parameters while retaining exemplary audio performance. The result is a total of >60dB error correction within the entire audio band, greatly reducing all types of distortion originating from the power stage and output filter.
- >75dB loop gain across the audio band for ultra-low harmonic distortioin, intermodulation distortion and negligible output impedance
