Our Technology


Fiberdyne Research amplification technology utilizes the Indice Semiconductor Continuous Sigma™ proprietary power control algorithm that is able to remove switch mode bridge error and noise in real time, offering a breakthrough in high fidelity audio whilst maintaining high efficiency.

The technology addresses the limitations of today’s Class D amplifiers which inherently introduce inter modulation and harmonic distortion due to the carrier frequency modulation and inadequate adaptation rates.

The amplifier technology uses a multi feedback system which naturally rejects switching and power supply noise.

The Continuous Sigma™ encoding method allows the amplifier to compensate for the natural non-linearities of MOSFET’s and provides an exceptionally flat gain curve.

Continuous Sigma™ is an asynchronous switching algorithm reduces the EMI profile with no fixed carrier frequency present.  

The switching speeds are 3-4 times faster than the standard D class amplifiers has allowed us to shrink the magnetics of the amplifier down to produce far more compact and efficient products.  The technology is perfect for the evolving EV Automotive market with the amplifiers running at greater than a 92% efficiency.  All of our amplifiers are passive cooled and we achieve this without having to resort to cast alloy finned heat sinks.

Fiberdyne Research’s advanced DSP algorithms are capable of powering entry level amplifiers across a number of power levels from 300W 8 channel entry level amplifiers all the way through to 4KW 24 channel amplifiers with distributed system topology complete with room correction and advanced ANC features utilizing digital MEMS microphones.
