12 Volts Hifi Amplifiers - Car & Computer

As "M," a mod can give orders to James Bond. That's quite cool.

In my case, it's not a cap, it's a yarmulke.

Re: I am awake......

But here we have the winner of the day.

he doesn't even bother to read the subject post = post #1

he doesn't take 1 minute to see my posted schematic in post #2

he doesn't read my desription of my idea, in short, in post #8

And I did read it, difficult as it was...........

Hey Halo... isn't this awefully close to turning into "Monkey Business"?

Careful, you might get a good chastising by HaloJoy 🙂

Re: What OP-amp for 12V single supply?

I attach my circuit again.
need some more feedback

I have a question:
What audio OP-amp should work the best with 12V single supply?
Maybe TL071?
It uses JFET input, so a bit higher noise.

But cars are a bit noisy too. So that will be alright,
I think.

Noisy?
Audio quality in your car, halojoy,
if is noisy or not, is your own choice, my friend

Now, if you buy some car with high noise level inside
and use TL071 (bit noisy as being older jfet based op)
how would you expect anything but get noise in your music .. ?




Recommend by Lineup Audio Lab:

1. get your self a low noise car.
Below -80 dB noise level margin is a good target.

2. of course your jfet op-amp choice should match your low noise car
for 12 Volt operation, may I suggest you have a look
at this welknown ultra low noise audio jfet amplifier from burr-brown: OPA2134

3. you haven't got any more detailed schematic
are you afraid to show all details .. or what ?

The one image below is nothing to tell me
what if this is any good or bad.
Sorry halojoy. Your stuff is nothing to post here.
We have better stuff than that crappy circuit of yours.

Wow, slamming Halo! To me that's quite ironic, since by your posting style and formatting, you remind me so much of him. For a while I thought you were him. Anyways, he was a nice guy.
