@bcerauli suspects there is a AD/DA converter in the SMSL AO200 and he wants a method to test and see if there is a AD/DA converter in it. He suspects there might be a AD/DA converter in it because SMSL calls it a digital amplifier.
.. pant... pant... what a tongue twister...lol!
My understanding is that a true digital amplifier will convert any analog signal you feed it to digital and then back out to analog again, the AO200 does have a USB input (so it definitely has a DAC) but I'm wondering if the RCA/XLR inputs bypass any sort of AD - DA round trip and are only being amplified in an analog state.
...Class-D is quantized/digitized in time (at a very-high frequency) while the amplitude remains analog.
It's ridiculous and just mucking with peeps minds...class-D might be called "digital" in marketing terminology.
Isn't that the, "◦ Digital Power Management Algorithm?"
Yeah...I guess. I'll have to study that thing to see what's up.Isn't that the, "◦ Digital Power Management Algorithm?"
This documentation looks as if the chip itself only has analog inputs, so I assume if theres any AD/DA going on it would have to be something SMSL implemented themselves, which seems unlikely.
Supposedly Lyngdorf?
There is no digital audio amplifier!
Yeah I know as long as we have current tech....but the "digital amp" thing means signal handling up to the last output device.....fwiw
I understand, but there are some amplifiers which convert all inputs signals back to digital for processing and then back out to analog, and I'm asking if the AO200 is one of those amps
There are no power amplifiers that does that.
