привет . какое должно напряжение на обмотках ? надо одинаковое напряжение ? или можно разное ? Hey. What should be the voltage on the windings? need the same voltage? or is it possible different?
Конструкция этого УНЧ имеет большие недостатки! Нельзя располагать вход и выход УНЧ рядом, от этого идут НЧ наводки и УНЧ начинает гудеть, когда на входе нет сигнала!

Dear sir! for the board 420 x 420 we can use transformer (24-0-24) 10A and other board can use the one more transformer for supply preamplifier or fan.
Thanks for the honest review
In the video I see an amplifier I think it is the one of the IRS2092 which sounds louder the TDA8954 or the IRS2092
That is the max power supply. 30volts dual and 8amps which is good to push to the limit. required voltage is only 24v
Great video
Excellent job
this board how in bass which one is best car amplifier or this board?
Does the control kit use a subwoofer??
heat sink will not be so hot at 30 volts 8Amps power supply?
it hot sir. it need put fan.
How many ampere adapter have you used ???
How many watts, ohms, size speaker is best for this ???
i use 10A(24v-0-24v) use speaker 300w 4ohm size 12inch.
which class d amplifier board is best for ts w310 12inch speaker?
good job
Nice video
What is the volt and ampere of transformer
Subwoofer not giving full power if you modify this board and give 40+40 ac volt then check the result subwoofer work at very good power.
Can't it be put in "bridged mode"? One wire per channel?

No se daña el amplificador al conectar un parlante en un solo canal y dejar un canal sin parlante?
No
Use lowpass filter? Or Direct Power Amp board?
Better to use low paas filter.

The TDA8954TH in BTL mode can't do the job at 30v ac (42v DC) at 4 ohms. Would be (30*2)²/4=900 watts RMS! the chip will blow!
