KA2281 previously with various vu meter circuit I made , but all mono circuit stereo manufacturer has two channels has been a challenge but in the end a bit of trouble in the scheme worked beautifully :)

Original diagram 15, 16 pins between the 50k resistor connected in this way the circuit full does not work for an additional 15 numbered pin- 56k resistor 2 to pin connects seamlessly with all channels running ka2281 outputs 560 ohm resistor on the LED connecting optional 470 ohms can be used but lower values ​​of the LEDs more disrupt the flow can lead to integrated pull . Mp4 audio inputs with 12v circuit works , cd player, pc etc. . resources , such as low power amp can be connected directly connected to the output does not

KA2281 gives mono output for the 10 LEDs 20 LEDs hooked ikşerl was fine ring-shaped LED placement sequencing also be mounted on a panel with the template I gave much better results if you give
