Looking for a Audio 5Kw AB class amp driver circuit

[U230421]

Suggest me how could I supply my +\- 60 VDC for preamp or amp.

So the supply is +/- 60Vdc?
That yields in theory to a maximum output of:
+/-60Vdc = 120Vtt
120Vtt = approx 40Vac (1/2√2*Vt)
(40)exp2 / 8Ω = 200W
Count the various losses, headroom and safety margins and we're talking 100W/8Ω...
When bridging you can multiply it by 4, but depends on the current reservoir of the supply.
Oh, 'music' power at 1 kHz in bridge is... 1800W (really, just math!)

Hasan2019 - What is your specific application? That will be helpful to know... 🙂

Merry Christmas 6L6...

do we have a troll here?😱

Well said.
Could you send me any link to calculaye the whole system so far?

1. It should be use for loud speaker.
2. Big mics or sub woofer.
3. Stereo, mono, dont know which one is best.
4. Less heat losses.
5. Need to be a ideal topology that can be analyzed easily.

 

[6L6]

And to verify, you were originally asking for a 5000w amplifier?

A troll?........I think that if you are new to audio and the power numbers game played by manufacturers, you would soon realise that there is no real significance to the power ratings when we see 10,000W car audio amplifiers regularly promoted, even in the U.S.

It's amusing to learn what that number really signifies to people who buy the stuff but it's clear that all they really care about is bragging rights. The bigger the numbers, the better. Whether they are real numbers or impossible just doesn't matter when they are printed on the box for all to see

 

[Hasan2019]

Take oldish DBTechnologies PA2.0 or 3.0 well known schematic and just build it.

But what's the goal?
Full-band amplifier asks for ugly passive XOing, so out of interest.
Active digital XOing allows you to divide power between drivers. Since lows and subs are really slow - the can be easily amplified by D-class while relatively fast highs (compression driver) doesn't need such a power.

Ok. You just put a point to start.
D class is my next plan. At this moment I want to build classAB and ClassH.

Now discuss your knowledge on "Lows" and " "High". How do you want to amplify any audio signal with a particular frequency and how could we make its quality better. Amplified sound need to be clear without any exta noise.

Yeap. Its should not be a troll!.
In a big place of gathering you may need it.
Interesting to see how could we manage this huge power. Technology behind it.
One technician said me Car battery charger or something is used to supply the amplifier power. 12 v DC can make 220V AC, I saw a circuit system using 2 multivibrator then current enhancing is take place.

 

[Hasan2019]

Sample build from our local DIYer, Arnulfo de Castro. This build runs from 120vac transformer, if bridged it can drive 5kW power from 8 ohms load.

Really a nice project you did.
If you dont mind explain it with few words.

 

[Hasan2019]

And to verify, you were originally asking for a 5000w amplifier?

From here I can realise its expensive and impossible because its shows heatloss. So lets assume for 1k to 500w.

Great Sir 6L6.
You did splendid job.
Your project gives me hope.
But, Chinese cheap products are dominating here. Suggest me any of your design that starts with lowest cost. For sure many customer wants good quality.

 

[454Casull]

In my humble opinion, you are not at the right place. Sounds like you want to create a commercial product and know nothing about what you want to make. Hire an expert.

 

[Hasan2019]

With responses like these, I hear nothing but alarm bells ringing.

Sounds like Hasan has less than no idea what they want or actually need and is wanting to make a commercial product.

Hasan - How about you you tell us what your requirements are, what the end use is, and what your budget is.

Do you have any guideline to build a 500W system? Share your knowledge what you have done so far. Lets come to the point.
1. How do your supply DC voltage to your Amp?
2. Which topologies should I chose for cheap project and old type class AB.
3. How do you calculate /analysis your circuits in terms of gain, power.

I did explain as briefly as I can. Maybe you mean more words about this amp. 😊

 

[jaagut]

Waste of trannies, sorry.

Can't expect less trannies for a class AB topology. What's your bet amp for 5kW power?

 

[BesPav]

Can't expect less trannies for a class AB topology. What's your bet amp for 5kW power?

For what price range?
I would prefer Sanway or similar FP10000q bridged for 2 channels or FP20000q single-ended for 4 channels.

 

[UserAbuser]

I'm going to label Hasan an unskilled person with close to nfi that wants others to design stuff that they will sell for commercial gain.

Please observe their two other threads for reference.

"Current" control is a big issue using ClassD ?

Is class D amplifier suitable for 60Hz potential transformer?

 

[BesPav]

Now discuss your knowledge on "Lows" and " "High". How do you want to amplify any audio signal with a particular frequency and how could we make its quality better. Amplified sound need to be clear without any exta noise.

There are no need to discuss my knowledge.
Take DBX Driverack 260 or Driverack PA2 or Behringer DCX2496 and crossover audiobands as you wish.

 

[Hasan2019]

ask Mr. Nelson Pass.
A mingling or marriage of SuSy (X-series, bridge configuration) and STASIS (serial mode of output power devices for high voltage applications) maybe provides the wanted output power.[/QUOT]

Thanks a lot.
I will ask him for sure.
