only one cap mean no output transformer,no dc servo ic,no j fets,nothing else,1-1 cap +and - .
A bit like a traditional TDA1543 application, then...
Does that mean you can leave the cap out altogether if you have a DC blocking cap on the input of your preamp?
mean dac modules generated 0.5v gone.
That depends on the value of your DC blocking cap on input preamp.
The DA-M1 modules generate rather high DC-offset about 0.5V
Sparky Sbc upsampler 384khz play sd card(not stream!!!) 5v u cap psu - iso regen 7v u cap psu- Singxer f1 5v u cap psu- i2s
Detonator Reference 12 rail balanced u cap dac (No active or passive coupling or other stages ) dc offset removed by M10 preamp
Monyo : single ended 4 rail u cap dac.(4pcs lt 3042 reg, 2rail Dc in Analog,Digital) with decoupling capacitor
M 10 monorual mod. total 7 transformers-7 iso transformers
(Under the Develop)
Class D 2x 25w single ended ,direct connected to Monyo ,16v 100Farad u cap powered,volumio digital volume control,no relays,runtime 1hours /charge, charging time 5min without music stop.
(tested yesterday first, sound promising!!!!!)
the 20$ class D with ultracaps sound much detailed,blacker background than my modded m10
Wow, that sounds very promising! You use 6x 16V Ucap modules?
I was quite some time absent because my father passed away Tuesday 31 Oct.
Will need some time to recover before I can concentrate on DIY audio again.
In the meantime it is good to see you are designing class-D with ucaps Balazs, keep us posted!
yes,6x16v modules,bought this alredy a long time.only the class d module missed.really surprised the runtime with one charging,and the sound compared my monster size amp..overall new details come.
Now this is full ultracap chain ,without wall power , without noise,without unnecessary active or passive components,stages.
Interesting. Can you imagine how it would sound with a good sounding class-d chipset instead of the one you used, like ICEpower 300A1
yeah,this chipset sound class d flavuor.Cant listen long time.
