Mesurments

We shall investigate the distortions of our dibox in comparison with the device from Klark Teknik, BSS AR133.

Notice, that the signal level will always be at 0dBu

Let’s start with 1 kHz frequency:

SimpleWay D1,D2

As we can see from the chart’s, SimpleWay shows us a better result. However, 1.7 times difference in sound is not that significant. We believe that it is possible to find devices that sound better and have a higher sound distortion compared to those with less distortion.

Let’s go further : we have more interesting result after Intermodulation Distortion (IMD) Measurment.

We used; two high frequency signals sent on device input (with 1 kHz difference), and a spectrum analyzer to determine nonlinearity products.

We sent two signals on input: 18kHz and 19 kHz with 0dB amplitude.

As a result, parasitic oscillations appear in both directions with 1kHz step range.

In SimpleWay di-box their maximum amplitude was -97 concerning  to useful signals,  Klark’s -87 and this is not harmonic products, which are masked by a useful signal, now we can hear them.

We came up with the new idea of a more aggressive test. Something more similar to the real working conditions. We decided to analyze spectrum after sending a bunch of signals typical of the range of the guitar.

This is not a standardized method but it gave us a very clear result.

This turned to be a serious test for devices.

If the simple way has a minimal distortion between the signals which are quite comparable in amplitude with the noise, then Klark device shows us very clearly seen intermodulation distortion, and it’s not only a result that we see on the screen but we also can hear it.

There can be no discussion of an opened and dynamic sound with such configurations.

P.S. It was not our intention to negatively target a highly respected brand Klark Teknik, and their product. It’s just a coincidence.
