Max Input Voltage
Hi all
because i try to switch to akku- power i would like to know, what is the max. input voltage of the dddac?
thanks and greetings

no problem up to 15 volt is ok. more important is de minimum voltage of 11.5 Volt
Dear Doede,
Thx for feedback 😉
But 15 is maximum? Problem: with lipo this is a little bit on the edge in both directions 😉
3 cells have nominal 11.1V but charging end Voltage is ~ 12.5V
4 cells have nominal 14.8 but I think they will have something between 16V and 17V at fully charged.
So... good question what to do 😉

with 17 volts the 7810 on the DAC board will get a bit warmer, but it will still stay within limits
the 7810 will dissipate ~ 0,7 Watt at 17 volts
according to the datasheet the raise in temperature is 25 degrees per Watt, so it will be ok
Dear Doede,
Thank you for the feedback 😉
"Just in case" i put 2 diodes in series to the battery. This makes sure, that the Coltage will stay below 16v!
Works pretty good... and i don't hear any bad thing about it 😉
Will try to play with some capacitors on the 12v input... will let you know the results 😉

Volumio.org and a Raspberry Pi will get you very far. If you need top notch I2S output, add a reclocker such as the Kali.

It probably depends on what you mean by "Aurender clone". To me, the Aurender is a music server with analog and digital audio outputs (USB, computer network, maybe I2S). An RPI with Volumio (and the right extension cards) will do this nicely.
I could have done something wrong. But I bought 3 new boards.. Which say 384/24bit I mixed it up with my single board which says 192/24 bit... Now everything sounds 10 times as fast. Voices like chipmunks.

Hi Doede,
Is it possible to mix two DAC module boards version 3 (2014) with two boards version 2 (2012). Which mainboard should I use?
Many thanks,
HT

Not sure what you mean, really higher pitch or as way of speaking?
The boards are dac "only" so there is no timing element.
you can send me some more info to my regular mail to go deeper if you want.
yes you can mix them without any problems.
The blue board is the best mainboard of the two
I don't know what is your i2s source, but you may have linked a masterclock output (22/24 MHz) to bitclock input (usualy slower than masterclock, 64*Sampling Frequency).

Thanks for assisting. The thing is..nothing changed in that department. I just stacked 3 extra boards on top of each other. But I will check ....
i2s source is hifiberry digi+ pro
