JD-Xi Analog Waveforms seen on Oscilloscope

Post by CesarsoundOne »

Only to kill the curiosity, I connected the JDXI on an oscilloscope to see how are the forms of analog waves in reality. Filters and effects are disabled.

Nice!

What about the SQUare wave showing PWM at both ends, Say 10% and 90%?

Hi Paulo,
here we are. Actually the range of width is 50% to 90%, rotating the PW knob. There is a small width variation, as I can see.

Hi Cesar,

Thanks for sharing. I have the JD-XA and would imagine the waves would be close if not identical.

Hi Synth,

For sure, the analog waves of JD-XA are close, if not better. I will post other test I've done, showing the waves digital part (aka SuperNatural) of JD-Xi.

Cheers.
