If my son sets room volume, then only one LED goes on
(I have installed the lower resistance).
Of course that is not enough.
If I turn up the amplifier fully, then all LEDs work. The amplifier has 200W RMS.
I then used the greater resistance and as expected, the threshold was even higher, i. E. not even an LED lights up at room volume.
Since I do not know the circuit in detail, my question would be whether I can possibly use even lower resistance. What value must the resistance have at least? I would really appreciate an answer.
Greeting
many thanks for the answer. Unfortunately, I did not understand them correctly.
The diodes are all the same? I just made sure that the polarization is right.
The display works so far that the louder the music, the more diodes light up. If you turn up the amplifier fully, then all indicate.
The performance meter would just have to be more sensitive. Therefore the question, if one can install a smaller resistance? Or maybe an additional resistor in parallel?
I do not know the circuit diagram and the values of the components, otherwise I could calculate it.
Or did I still not understand the problem correctly?
Before you try changing the resistors you need to check the assembly.
The diodes are not the same however they do look the same at a glance.
See below.
The BAT85 the 1N4148 and Zeners look the same but you need to read the part numbers on the side.
If any of these are not in the correct place the kit will not work as expected.
Thanks again. True, the values of the diodes are of course different. I checked that with my son before installation. Also the right direction. I meant the LEDs in my answer.
