Hi Daniel,
I don't suppose you've measured the distortion of the new muses chip?
I'm curious as to how well it does vs the 72320 at higher levels, say 4V rms - any idea?
Best regards,
cv

Daniel, is 72323 hardware and software compatible with 72320 ?
Can one upgrade your old board, with the 72323.
Thanks...

Hello,
no, not compatible with the 72320.
There is no reason, the 72323 has better specs, need less external parts and is cheaper.

 

[Theodosis O.]

And what are the prices of the new boards and new controller ?
Thanks

 

[meldano]

Currently a little bit more than the old ones.
10->12€

Please update first post with revised pricing

 

[meldano]

Done
But we can close this thread because the actual version is only a small group buy.

meldano, please report your post if you would like the thread closed.

This is a great support thread for us that bought and made this muses 72320 volume.

Galvanic isolator

I solved the galvanic isolation of the controller and MUSES with an ADUM1400 (thanks Daniel for the suggestion!) 4-channel digital isolator.
Working perfectly!

Nice ����

Updated documentation (see first post).

Last chance for the USA group buy.

Hi Meldano,
If it’s not too late I’d like to sign up for a VC kit.
Located in USA. Thanks.

Hi Meldano
Thanks for the boards received today, what connections need to be made between the two main boards for balanced input selection, I see that J1 is set from pin 1 to pin 2 for the balanced volume.

 

[meldano]

From bottom to top:
- Main board with assembled Relais and X1,X2 connector
- Volume board
- Full assembled main board
- Volume board
- Controller board

Please note: bottom main board is connected with X2 to the other main board and with X1 to all other boards.

Hi Daniel,

I don't know how to send a picture in a private message, so I'll post it here.
Please correct me if I am wrong. Thanks.

Hi

I'm currently ordering according to Mouser BOM in post 1.
The diode TS4148RYG is on backorder until April.

I found some other TS4148 but they are in other housings (not 0805).
Can someone give me a suggestion on what would be compatible, both size and function?

Thanks

I think I found out that 0805 is equal to SOD323?!
Perhaps this would work 621-1N4148WS-13-F?
