You can use the Dac to control powered monitorsIsn’t having a volume control on a DAC like having a volume control on a turntable or CD player?
I don’t get it.

Looking good.D30pro updated filter response 44.1KHzView attachment 114130View attachment 114131
The same applies if you want to use a DAC directly into a power amp, so you can do without a preamp.Many thanks, everyone. I wasn’t considering the use with powered monitors.
D’OH! (etc.)
Firmware.Looking good.
Did this progress halt production and release of the D30pro or will it be a firmware update?
Now that's steep! Is this using what Cirrus Logic already provides or did you have to create this from scratch?D30pro updated filter response 44.1KHzView attachment 114130View attachment 114131
It can make sense of the digital volume can be controlled by USB.Isn’t having a volume control on a DAC like having a volume control on a turntable or CD player?

None of the stock CS43198 single speed filters are down by more than ~6 dB at fs/2, so I imagine those may be 3 and 4 (FIR and IIR versions, respectively).Now that's steep! Is this using what Cirrus Logic already provides or did you have to create this from scratch?
Is it possible to "create" new filters not already programmed into the chip?None of the stock CS43198 single speed filters are down by more than ~6 dB at fs/2, so I imagine those may be 3 and 4 (FIR and IIR versions, respectively).

That's called imaging instead of aliasing and it happens above 22.05kHz rather than 20kHz. BTW I wonder why the stopband is 21kHz rather than 22kHz, perhaps a limitation of the programmable filter settings? Anyway, the most popular ~0.55fs stopband filter is still there, as well as the NOS one so that others can use it with their own software upsampler, should be no more compliant I suppose.So I guess this is where the discussion starts if some aliasing above 20 kHz or a frequency response 35 dB down at 20 kHz is to be preferred...
oops.That's called imaging instead of aliasing and it happens above 22.05kHz rather than 20kHz.

Wow you are so fast! So does it mean it is fixable?oops.
There are a number of situations where a volume control on a DAC is useful. E.g., the toslink output on all smart TV's I know is fixed volume. So if you're going Smart TV->DAC->active speakers, that's how you control volume.
Yes. Will update tomorrow. Also we just decided to add extra ones instead of changing them.Wow you are so fast! So does it mean it is fixable?
Just go with Smart TV (headphone-out)->active speakers, it's usually good enough and allows you to use TV's remote for volume controle. I don't get why people are obsessed with DACs, pretty much any DAC is good enough.
I did wonder about that. Seems odd not to get closer to 22k if you can, and move the "corner" closer to 20k.That's called imaging instead of aliasing and it happens above 22.05kHz rather than 20kHz.
