900W H-class PA Amp with Limiter

[NMOS]

Hello Apex

can you provide schematic

 

[Sneha B]

Hello sneha,

Dont go with any pcb design.

So much people are uploading bad design.
So much errors and all,
Just sir mile( apex audio) designs are tested himself...so you can use it with trust......🥃🥃🥃🥃
I suggest you to make your own pcb design...
Btw, come soon back,

I agree 100 %

thats why I have design myself Class D UcD PCB from schematic Mr. Kartino

Dont think its easy like class AB/H,

also you need PCB design software to proof PCB routing mistakes V/S schematic otherwise sure you will get first time smoke

Be aware to buy amplifier PCB from 3th party, make it self

I losing time and money, and be aware to buy IR Mosfet driver, Power Transistor in epay if you design amplifier

buy from mouser, digikey, farnell, tme, lcsc and you will have working amplifier

Thank you so much sandeep sir and NMOS,
You guys are right....i found some mistakes on pcb design
And yes sandeep sir i am coming soon.
Thank you ones again,,
Btw sandeep sir your amp,,, i like it.even i'll also do same thing..

Hello sir mile,
I just wanted ask if use 0-55-110vdc bridge mode, how much AC V comes out....at normal clip...

Does anyone know who design this pcb ???

how about sound sir??

@stewin,

you asked Yamaha for permission to use their design ?

Stewin,
please upload the lt-spice file if possible.
Thank you!

 

[Sneha B]

Some please tell me, How to bridge 2 H900, and signal clip led meter,
Thank you

 

[sandeep kayarkar]

Sneha, for bridge mode wiring,
And even im looking led vu (ON,SIGNAL,CLIP,PRO)

Sir Mile, what is going on? H900 bridge mode, just 20 Vac but spkr pump good but.....

Your step driver not work, there must be 40vac on output.

 

[sandeep kayarkar]

Sir mile voltages as per ref.file is ok....but still....no voltage above 15vac single ch.

Mistake Pa protection

Hello,
Sir Mile, i found a difference between the circuit and the PCB of Pa protection.

Diode 4148 surrounded in red is connected in the circuit with the anode to the "pro" output of the amplifier. On the PCB, this diode has a cathode to the "pro" output.

Which option is correct or do both options work?

Anode to the 'pro' is correct.

Limiter

Hiii.... everbody especiali Mr. Miles can NSL32 replacing by this circuit ???

 

[stewin]

does any one have a working class td schematic and layout or a ee engine layout and schematic?

kindly share here
