RCA output voltage goes up to 2V while XLR can be 4V or 5V on some DAC. How is the Audiophonics / Hypex Class D amp dealing with the...

Thanks for the good picture. Ok no RC. ALSO, very important Warning information that I found afterwards: Application note Amplifier...

Unable to determine from your image, it looks like "no". Easy to determine for yourself if you have the equipment in front of you...

Yes, and this board looks like it is the cheapest way to create an HT Bypass function as mentioned here: Same power amp for AVR and...

Which question did you answer? For sure the diagram is correct, it's from the Hypex's document. Is there a RC network (100nF, 100 ohms)...

I've noticed that Audiophonics uses a small circuit board marked "RCA/XLR SELECT" on many of its own-brand power amplifiers. Is this...

I found the source and it says: Why must DSD be converted to PCM in an FDA? Because DSD is not a digital signal, it cannot be processed...

I think so. I know nothing, as many noticed here, but if I remember correctly, it is teated as such in a Full Digital Amplifier. If the...

Get yourself solder rosin flux for a perfect solder job. You can get a pen applicator of no clean flux but after you will want to clean...

I will make mistakes if I need to solder 100 metal film resistors to an empty attenuator. Otherwise, I can be meticulous. About stepped...

I started the conversation in the DIY thread for a reason, which is to eliminate the weakest link (after the room and the speakers). To...

So class D are not bit perfect, correct? They could create distortion by a wrong (none accurate) width, or some kind of jitter, correct...

Most likely. You'd have to ask Axign to be sure.

Theoretically you could vary an amplifier's gain by tweaking the feedback loop (classes A, A/B) or modifying the switching processes /...

True. :confused: But they switch (0 and 1) some kind of pulse (samples) at a frequency that complies with the Nyquist–Shannon sampling...
