vu meter

[karma]

i was wondering if anyone played with vu meter on there amp
and if thay had a layout that works with a zen or aleph4. i saw one installed on a marantz and it just had a single power resister
is this going to work?and if so what k ohm

thanks......

found layout woohaa

its was analog not l.e.d

Hum i might have a Schematic for a good vu Meter. Are you looking for one for a actual meter or led's.

post schematic

 

[jleaman]

Of what kind. ? both. ill have a look on my dvd' Back up of schematics. I got lots. Even every qsc amplifier made HEHE opps. shold have not said that. : O )

non l.e.d the schematic i found is no good dang

Have you built the Holton AV800 amp
... or just N-channel ?

DVD with lotto'schematics? sounds
cool.....

Got any ideas for mods for the
AV800? such as;

...... any add-on circuits or mods, ie protection, clipping indicators,
anything .. kewl ..

I'm always trying to find elegant solutions

Trying to avoid speakers catching
on flames if the amp goes berserk

Im in the middle of gathering the parts for the av800. Id like to sell the n-channel. i dont use it. It was my frist amp though. Protection on my amps neh.! Nothing but fuses on them that is about it. I might think about it later on but i never push my amps to there extent of blowing.

got it i hope

first pic works great meter does not jump around it hovers at the v the amp is pumping out now to make a nice face plate for my meter maybe some blue l.e.d for a back lite hmm mr pass can i copy yours just joking

all the above presume that you are going to modify a meter face to replicate VU. If you use a diode in the feedback loop you can actually measure log units on a linear scale -- see National Semi's application notes on logarithmic and exponential amplifiers.

Re: got it i hope

Hi Karma, I'd liked to know if this is the layout that you are using for your meter and how is working right now. Also can you tell me the values of resistor, capacitor and diodes.Thanks in advance.

still

working here is a link that will give you all the values
