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
