Thanks for you interest.

VCC = 22 to 50 V +- DC

As per signal-to-noise ratio... i dont have equipment to measure it ... but according to my own experience of 10years in audio amplifiers making and feeling, this amp has very low ratio....

This amp is very good for Subwoofers..but need to use sub crossover preamp .

I have made 6 amps till now.. No issue at all.. All my customers are satified with this..
 
Runs with +50 0 -50 vDC at 6amp..

Compaired this amp with branded 450w car subwoofer amp and found this amp gives more power full bass and high audio output... My testing was simple.
 
Thank you for the information. Do you have any Power supply kit, esp. SMPS for this particular Amp?
 
No sir, I use Transformer based Power Suppy..

One have to connect transformer secondary wire directly to the amp PCB.. all powersupply components are installed on the amp PCB.
 
you cant compare a car amplifier with a 450 W RMS home amplifier mate. Can you tell me which car amplifier you used? i am curious to know, since I want a 1000 W RMS amp for my house with a built-in crossover switch. How to go about it?

you meant high signal to noise ratio?
 
Rakesh, Shouldn't VCC should be at least +/- 60V for delivering 450W rms @ 4 Ohm (for +/- 50V, it will be 314W max), may be I am missing something.

I would take 50 % efficenty here...not more than that. I that case it would be in the terms of 300 watts. For this amp to be on 450 + we would be needing 70-0-70 at more than 7 - 7.5 amps.

Yeah that's right. But I think the price is ok with that, provided he gets rid off some of the cheap cappys & Pottys:ohyeah:
 
dear friend i wissh to know more about it? is it a sub woofer amp only? if yes then what for channels? plz reply bcoz id ecided to buy FX5051 in this week.
 
Yes you can use this amp to drive channels too... like this ..


Till date i have made 7 amps, two of them are stereo amps..
For all the others,.. i want to tell that , i have not designed or created this amp, i have done some modification in design and components according to my knowledge... and i make the full amp (from PCB to Final product)... My test was simple ....

If you want to purchase then make a reply....THIS IS NOT A GENERAL DISCUSSION FORUM. for all other question if any one wants to ask.. he is heartly invited at my place to feel the amp in action.. and meet my buyers to see the performance of this amp...

Any way Thanks to all for repling and showing your interest in the Product.
