Thanxz Nikhil,
Well we are into Pro-audio, mainly manufacture high power class-D amplifiers [500W to 5kw per channel], Active amplifier modules, Active speakers, Custom active systems.
The amp in those pics is suitable for driving large subwoofer drivers which are rated at 2000W @ 8ohms [18 to 24inch drivers]. These are especially meant for large sound reinforcements in theaters, concerts, live sound etc.

Kanwar, great to see you and Zypher going places. Going by what I hear about the work you did for Ashok, Sid, you are all equipped to storm Home hi fi too!
The last intl show you participated was in China right?
How is the response to a world class Indian product at these shows?

Thanxz Mate..!!!
We did total of 3 shows till now, first one was in Beijing 2012, second one was in Guangzhou 2013 and third one is recent we did in Frankfurt 2013, in all these shows we were the first to launch products from India, till now no one else did this other than us.
In all these shows we did impressed a great deal of visitors who came all over from the world including sound rental companies, manufacturers, project companies, installation firms etc but there was lack of competitive people in China who can understand the level of engineering involved in products, whereas in Germany it was very different experience altogether when you are complemented by those people who are skilled in the art and they come from big names in pro-audio. R&D engineers especially were impressed and some were even shocked to see this level of product engineering from India.
Let me tell you we are the FIRST IN THE WORLD who have managed to developed a 10KW amplifier which is based on Continuous Average Power output not EIA/EIAJ/PEAK power testing methods used by others.
Cheers,
Kanwar

That is amazing (even though I don't understand it 
). It is one thing to be "world class," but quite another to be a world pioneer in technology.

Which thing you didn't understand? The test methods of amplifiers?

Yes...
I understand that there are different power ratings for continuous power, and peaks that an amplifier can reach temporarily. I understand that, especially in hifi world, marketing departments massage all these specs and make them look good. There are two abbreviations there that I never heard before.
This is probably all I need to understand, as buyer/listener

Kanwar/ Sanjay - maybe you can do the same in delhi some time. I think a lot of pro gear can be used in home applications. Subwoofers and power amps seem like good candidates, if not speakers and source - but you never know.

EIA=Electronics Industries Association of USA
Method= feeding a 1khz Sinewave with 33mS ON time and 66mS OFF time burst which usually gives 1.2-1.4X rating of continuous average.
EIAJ= EIA of JAPAN
Method= feeding a 1khz Sinewave with 8mS ON time and 92mS OFF time burst which usually gives 1.5-1.7X rating of continuous average.
Both were devised for consumer electronics but marketing charlatans in pro-audio took them on the spec sheets to look good over paper.
FTC=Federal Trade Commission devised the real Continuous Average Power which demanded the amplifier to give power output for 1-5 mins with continuous non burst Sinewave sweep from 20-20khz. This test is NIGHTMARE for amplifiers whether Pro or Home audio, only chosen few pass this test.
CEA= Consumer Electronics Association, Less stringent than FTC, normally only one channel is tested for full power and no preconditioning of 1/8th power like in FTC.
Apart from these home audio AVR/amps have bogus ratings goes by the name Dynamic power, IHF power, Music Power nothing but marketing BS.
I hope this helps.

Are you participating here: PALM Expo 2013
No Capt. we don't participate in local exhibitions. Pro-audio scene in India is pathetic.

With pro gear you have much better variety and affordability.
I can understand this in the area of sound cards, interfaces, monitor speakers and that sort of thing, but does it also apply to areas such as amplification? Two things occur to me about this...
--- if I connected one of your PA amps, say, between a pre-amp and domestic-hifi speakers, would I not just end up with smoke coming out of my speakers?
--- I attend a lot of live (Carnatic classical) concerts here in Chennai. I do so because the live-music experience beats all else, but if I simply wanted sound quality, I'd stay at home, because even a basic hifi is considerably better than almost every PA system I've ever heard. Yes, of course a lot of this is due to the combination of bad hall acoustics and an idiot controlling the gear.
I'd be really interested in your thoughts, expanding the above quote, on the potential place of pro audio in the home. Perhaps a new thread would be the place for that?
As long as you select an appropriate power level matched amplifier with your domestic speakers. For example if your speakers are rated at 100W then you can safely connect 200W Pro amp with them without smoking.
Good and bad quality PA equipment is everywhere along with choice of operator controlling the gear. Sometimes the venue chosen is horrible in terms of acoustics. The blend of all these factors is responsible for the outcome.
There are many factors which govern how to select and incorporate pro-audio gear in to home audio usage, i think a separate thread would surely help here.

If you know what your doing you may be fine. Theoretically a very aggressive limiter could be employed. At that point all the extra power is kind of wasted.
If you are actually pushing more than 100W into a 100W speaker for home use, I would argue it is not the amplifier you need to be concerned with, rather you need more speaker.
The amp will of course only deliver what is asked of it defined by your settings, so again in theory even a very high powered amp could work with 100W speakers if you are not pushing it, but if actual 50W is all you are using then you wouldn't really need to worry except for the transient peaks which may put the driver past xmech, again depending on circumstances such as source material and settings. Obviously you don't want to be putting 12 db of boost on a 8" home audio woofer at 30Hz because the manufacturer rates a -3db point of 25Hz like many newbies do.
Really it is all about how you use it, yes it would be a waste of power though I would like to make one final point, clipping a 100W amp trying to make it do 200W is not good for your speaker either. Some would argue clipping is worse than too much clean power for very brief periods, how much power and what duration depends on the speakers being used of course.

Can the discussions on the post made by Thad (post no.34) & the relevant ones following it be shifted to another thread??? It makes sense to continue the discussions in that thread rather than go off topic in this thread.
Request mods to do the needful.
Thanks!

Hi Kanwar,
Please do start a new thread on how to select and use pro-audio for home use (both music and home theatre). This would indeed be very helpful for those of us who believe that pro audio and home audio cannot mix. If you can post some of the work done by you on the home audio front, that would also help to get a perspective.
Best,
APK
Yes. In audio from flea watt amp to 400w Digital amp all products have their significance. I would love to hear high power amp driving ESL or high impedance speakers. Or for that matter big subwoofer driver handling transients of low fq in music.
Regards
