So you can insall this Vu meter LED LM3914 or LM3915 or LM3916 directly to Your Loudspeaker/Transducer (pasive speakers).

Also You can turn this circuit into DOT or BAR mode just like that You want, so please watch carefully how to turn into BAR or DOT mode.

When I test this circuit, I use my DIY 4 Transistors 150 watt amplifier to play the music, you can see also how I build that Amplifier here: [ Ссылка ]
