MCLK Input is working but it needs a new firmware for the cpld i haven't yet adapted for download. I think to put online the new cpld firmware soon.

When you check MCLK Input, the cpld works in slave mode and it accepts the clock from pin7. Pin1 and Pin11 are used for clock selection.

@jackal29a: Thanks so much for elaborating this - very helpful 😉 .. I'll look into it in the days to come and see if I can get somewhere with it.

And, yes, if a BB DAC uc programming capable person could "chip in" 🙂p) on how to program the registers I'll be pleased to hear about it as well.

Greetings,

Jesper

it works with 45.xx and 49.xx too.

I need to add a cpld firmware selection in the maintenance tool, in this way you can choose,

cpld master, cpld slave 22/24, cpld slave 45/49
Click to expand...

Is possible to swap onboard 22/24 oscilators for another 45/49 oscillators?

Any oscillator sugestion for this swap?

Onboard 45/49 oscillators make very easy reclock using Acko isolator/reclock board.

hello thank you for the GB4, i hope to ship all during this week, i got some delay with shipments because i was away from Pisa.

I just uploaded a firmware version 1.072 with I2C speed at 100Khz.
Please use this maintenance tool http://www.amanero.com/oemtool111a.zip

The OnMute event is enabled and the OnVolumeChange too.

About the OnVolumeChange insert address [0x49], register [0x0], and the number of sequential registers to modify with a volume value between 0 - 127 for example 8.

Thank you!

Hi Domenico,

Thanks for upload new tool and firm!!
I have a problem with 1.069, but now solved with 1.072.
Thank you very much.

But I have a question.
I already find 1.072 and 1.072 192k with oemtool110, so what's difference?
