Our DSP crossovers have been inside popular studio monitors for more than 10 years, which means some of your music content was mastered with our products. Since our customers are the brand, we are more like “Intel inside.” Nevertheless, we have likely infiltrated your audio world. This flexibility really helps when it comes to creating new products.ĭanville Signal’s customer base has traditionally been aimed at other manufacturers, so you may not be well acquainted with our products.

We also manufacture all of our products on our own internal automated line in Cannon Falls, MN. Danville now has an engineering department so our products evolve from a collective effort. Of course, a village with one hut is not much of a village, so now the story moves to our team, since Danville Signal is no longer a solo engineer and a few subcontractors. In my view, the SHARC is the gold standard of DSPs for audio processing. I designed my first SHARC-based DSP design in 2000 with a first-generation Analog Devices’ floating point DSP. In 1998, I founded Danville Signal Processing with the intent of building audio signal processing products using Analog Devices DSPs.

I think this was a fairly natural transition for an analog engineer since the math is not so different and the applications often overlapped. In the early 1990s, I designed noise reduction products using Analog Devices DSPs. Besides learning a bit of circuit theory, I think the other skill I learned from this collaboration was the ability to listen critically, which is essential for any good audio designer. Modifying existing circuits is like covering songs, creating new circuits is more like writing your own material. At this time, I invented the split passive phono preamp, which was later patented. By the end of my junior year, we started designing more original circuits.

We started by modifying Dynaco preamplifiers and power amplifiers, and we had some commercial success. I was a sophomore with an electrical engineering major.

In my youth in the mid-1970s, I joined a small team of gifted audio enthusiasts not so different than the audience and contributors of audioXpress. I don’t think I can tell the dspNexus story without sharing a little of my personal background and later the founding of Danville Signal. The dspNexus DSP Audio Processor serves as the control center, the preamplifier, and the DSP engine for powered loudspeaker applications.
