My "Network Soundsystem" :-)

Hello Volumio-friends,

here is my Volumio-Project…
I have implemented all Volumio-plugins (GPIO, Spotify, Touchscreen)
Only a “Multiroom”-function is still missing :frowning:

  • Raspberry Pi 3
  • Class-D-Amplifer TDA 8920
  • Symmetrical power supply 2 x 25V/ 230 VA
  • Volumio Release 2.041

Hi,
Great job !

Could you please add more information about DIY kit used (alim, soft power,class d, relay for pre-amp…) ?
Did you also homemade the speakers ?

Thanks in advance

Hi,
my English is very bad, but I try … :wink:

Soft-start I haven’t build in, only the Loudspeaker-Protection behind the amplifer I have implemented. I have bought following moduls/parts here:

https://www.amazon.de/gp/product/B01KPQTW34/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1

I haven’t build in a Pre-Amp. The Line-In I have controlled with 12Volt Relais, but I will change them in following modul:

The Loudspeakers are selfmade. The Chassis are from Dayton:

bzw. Oaudio:

At this time I build also new 2-way-systems with SB Acoustics Chassis:

The casing I have a little bit redesigned:

Hi,

MeanWell, RS-15-5

@vinc
I can use the Touchscreen and I can use the button.
The buttons are more comfortable

@danielfelix
I can create a block diagram, but it takes a few days.

Claus :slight_smile:

Thank you! I wait for the diagram, there is no rush.
