Audio systems are currently designed for a specific product. Wouldn’t it be great that the entire audio system is adaptive so that it can be automatically optimized to create the best audio experience possible?
During recording sound is controlled by mixers and equalizers. At reproduction, a DSP is used to personalize the sound experience or to optimize cross-over frequency of loudspeakers. The loudspeaker, that ultimately produces the sound, is usually driven by an inflexible, non-adaptable amplifier. To overcome this inflexibility Axign developed a fully programmable amplifier controller to create the best sound experience.
The digital amplifier controller of Axign, AX5689, compares the signal at the loudspeaker terminal with the input signal. All disturbances in the loop, such as power supply ripple and non-linearity from the reconstruction filter are compensated real-time and suppressed thanks to the extraordinary high loop gain. The analog signal at the load is converted by a high performance low-latency feedback ADC. It combines a low-latency of several nano-seconds, for loop stability, with a high dynamic range up to 120dB for professional audio. With only the input stage of the ADC in the analog domain the AX5689 is highly digital and consequently has all the features like programmability, self-learning and robustness of digital signal processing. Due to the digital nature of the design it is nearly CMOS technology independent.
The Axign amplifier controller is fully digital which makes it insensitive for component tolerances.
This allows for high order loop filters, up to 7th order, to make a high open loop gain and steep filtering possible. Thanks to the ability to program the transfer function loop filter characteristics can easily be changed, for example noise shaping from 20kHz to 40kHz and vice-versa.
The signal at the load is directly converted into a digital bit stream.
This implies that the error signal, being input minus output, is digitally available. As a result, the feedback signal can be analyzed which provides information such as clipping or a short. Also an “open” can be detected based on the expected output noise level. It is even possible to detect unwanted signals such as possible oscillations. A DSP in the system can instantly change the loop filters based on this information.
The amplifier controller contains multiple high performance ADCs.
Next to voltage steering of a transducer, the current through the transducer can be measured. Also this information is available within a few nano-seconds and can be used for protection purposes or even to drive the transducer in current mode.
Feedback is taken at the load.
Therefore, all non-idealities such as distortion from the reconstruction filter or power supply disturbances, which is especially of interest for class-G/H systems, are strongly suppressed thanks to the high loop gain. If need, notches can be programmed at critical frequencies.

Enschede, October 6, 2017. Axign announces that it has received an investment from Innovation Industries, Innovation Fund Twente and Innovation Fund Overijssel. With the equity investment, Axign will ramp-up the volume production of its first audio controller chip, the AX5689. With this device, manufacturers of consumer audio devices can increase the sound quality to premium audio levels at significantly lower cost.
Jeroen Langevoort, Chief Executive Officer of Axign states: “Streaming audio will become the future standard for music reproduction in homes. We believe that our product contributes to this trend in delivering unprecedented sound quality in small cabinets, whilst provide cost saving to the manufacturer. Reactions from consumers are fantastic once they hear music with our solution. It ranges from “unbelievable, open and transparent” to “I never heard such detail, although I listened to this record over and over again”.”
Nard Sintenie, General Partner at Innovation Industries says: “We believe that the technology of Axign will bring the best audio experience at lower cost for consumers in the mainstream market segment. We are excited about leveraging the high-tech network in the Netherlands to enable this unique breakthrough.”
Pieter Rhemrev, manager business unit Capital at Oost NL, considers Axign an example how companies can grow in the financial eco-system of the Twente region. “We’ve been involved in Axign since the beginning. We’ve always had confidence in the company and the quality of their chip. Thanks to our prior investment from Innovatiefonds Twente in 2015 Axign could begin production of their chip. Now, with this new investment, they will be able to start mass production. This development will have a positive impact on the job market in the region”, says Pieter Rhemrev.
Axign Controller Platform: opportunities for all stakeholders
The Axign Controller platform offers opportunities for both manufacturers in the Pro-Audio markets as in the mid-range to high-end consumer audio markets. The system achievements are second to none in comparison with other audio products on the market. In next generation products, Axign will build on its high audio quality and combining it with increasing functionality to maximize cost savings for audio equipment manufacturers.
September / October 2017:
Axign demonstrated the AX5689 at the XFI Premium Audio Show, September 30 and October 1, 2017.
The audience was amazed by the detailed and clear sound stage. Unbelievable, they said.
We invite you to listen to the AX5689 audio controller as well, and convince yourself.
Location: Koningshof, Veldhoven, The Netherlands.
The new AX5689 performance figures on system level are extremely good:
The listening experience is extremely good:
The perfect silence and incredible sound. Audio under your control.
Note that the 3 lines are on top of each other. The THD+N is limited by the low N, even at 6kHz.
In combination with a high damping factor (the output impedance stays below 2mOhm within the audio band) and its load independent behavior, loudspeakers will produce their best possible sound.
Axign has been at the Consumer Electronics Show (CES), Las Vegas, 5 – 8 January 2017. During the exhibition the features of Axign Audio Amplifier Controller IC were demonstrated. Thanks to the digital flexibility, robustness and feedback at the load, it is suitable for nearly every amplifier system.
Please find some interesting links on CES2017:
Axign developed a new demo board with even better sound performance.
It can be used for evaluation purposes under NDA.
This board can also be used as a reference design for your amplifier application.
Please contact Richard Langezaal, Director of Marketing or send an email to: email@example.com. for further details.
After two years the location of the Moutlaan became too small for Axign. We found a new place in “de Spinnerij”, where more innovative start-up companies are located. It is an old spinning factory from the historic cotton and linen era of Enschede. The spinnerij dates from 1911. In its time it was a high risk innovative project of the young entrepreneur Ledeboer, who took the step to built a factory around the spinning mill powered by a steam engine. Today it is an inspiring environment to be working in.
