AckoDAC based on AK4499EQ

[acko]

Sorry, I haven’t developed multi-DAC types with ext clock sync. Only 8-channel ones (on a board) driven by the same local clock for 2x4Ch L/R output. I heard AES67 can do this ext sync. Something to look in future if there is sufficient interest…

 

[Amplifier dude]

That’s the only reason for using AES67. Otherwise you might as well just use Roonbridge. It’s not actual Ravenna you’re using if this functionality isn’t available.

 

[acko]

The functionality is available already, being AES67 compliant but not tested yet as a system with two separate 4 ch DACs

Akko: I sent you an email via your website.

@acko: There is growing interest in software based active crossover systems utilising Acourate or AudioLense. Such users will be very interested in a high end multichannel DAC with USB input. I am very keen to try AudioLense, hence my interest in your developments.

Hi Ian, I am just going through your message, thanks and will respond soon.
Yes, I am trying to gather more information on typical scenarios for multi-channel applications so appreciated all the reports

Migrating design to use the latest chipset AK4191/AK4499EXEQ, stay tuned🙂

Growing interest for directivity will probably see use for more than 8 synced channels...

Thanks for the insight. I can now see why people wanting at least 12 channels. I will do an 8-channel version first, there is more complexity and costs with AKM parts….

 

[Studley]

8 channels will be enough for most people I think

The chips have landed!
Time to get cracking…

 

[acko]

The samples are already spoken for. If anyone need these parts just let me know as more orders planned

First happy programming... and please post the results 😉 as new higher order SDM and resistor switching 😀

the AK4191 seams to be from year / week 21 / 28 and the AK4499Ex as 22 / 14 ...

@acko : a request - please include a digital volume control on your 8 channel DAC.

 

[acko]

Digital volume control is the standard inclusion

Is the final version in Dual mono configuration with AK4499EQ in the final version of the release?

 

[acko]

Both typical 2ch stereo and dual mono versions
