Thank you again Olaf !

Thanks for the reply's you all,
I found an easy circuit, I've tested it and it works fine ! Circuits Online - Schakelingen - VU meter It seems to work from the line inputs.

🙂

Hallo all. I have used this circuit before on VU meters and it works fine. But now I have Sifam db meters that I want to use and this circuit adjusted on max can only drive them a third of their full scale. The resistance of the new meters are 5.5 Ohm. Any Ideas how to improve this circuit to drive them to full scale will be appreciated.
Regards

Hi Jan,
Here is the pdf of circuit I posted. I replaced the gnd plane with traces. Hope it is useful to you.

gerbers as per request by PM. I haven't tested it nor do I know anyone who has.

Thanks Prasi, I will save it !😉

 

[prasi]

Have you tested this ckt?

 

[Vrystaat]

Prasi, no, I have not tried it yet.

Do you have a schematic for you Rod Eliot board as a 404 message does not let me
enter to his site?

Rod Elliott changed his server a few years ago.

Change sound.westhost.com to sound.whsites.net

This is the current link to the meter page:

Hello. I'd like to build this VU meter. Can I tell myself when I can find the materials list of it?
Thanks

Many thanks.

Did anyone ever try Prasi's VU board?

 

[martinMK]

I built it just yesterday.
one thing though, i get 2.2vdc on the meter connectors without any signal going through, maybe there is a problem with the schematic.

 

[Vrystaat]

I have build Rods's circuit on perforated board, works great !
Remenber to short the inputs when testing without an actual input signal.

 

[martinMK]

I built Prasi version and face the 1.5-2.2vdc on meter outputs. Do you have any DC voltage on the outputs?

 

[martinMK]

Disregard my last post, parsi version works fine.. all is good.

Gerçekten hoş!. Bu arada yapacak daha iyi bir işim yoktu, yayınladığım ckt'nin düzenini yaptım.
