b)measurements/specifications

Frequency response is 20hz to 20Khz.

THD less than 0.5% at full power bandwidth

Damping factor is >1000

Slewrate is >65V/uS

Below are measurements all taken at 2ohms and mains voltage was kept stable around 245VAC ~5% on Industrial line.

d)actual cost of shipping to UK

The above pics and measurements are for dual channel amplifier only.

For 5KW monoblock which is single channel amp, the cost would be around 410GBP

Shipping by UPS says 230GBP for 32kgs from India to UK

This is usually enough to convince people to buy unseen amps from China.
When one arrives in UK. People will go to hear it in demo/session, and word spreads from there.

Can tell you now, At least myself, Ren, Tekasis, Saul, TweeterBox, Paulus would be anxious to see all this info.


Cheers.

To all,

This is an INDIAN amp which means fully designed and built in house by Zypher power labs pvt Ltd , not a low budget Chinese copy crap of some famous brand.

Output Transistors are Fairchild FJA4213/4313 Pairs 250V 17A each. 12 Pairs are used in output stage. And all power devices are in large die format TO-247 package, not some funny TO-220 used in other brands.

I hope this helps.

Yes man... smiley20 (Really need to read more of the forum)..

3U mono-block, delivering 4K at 2 ohms, with 4x speakons.

If it could deliver rated output continuously with 50hz sinewave input, without overheating or thermalling, would do well in UK Roots Circles.

Would need pile of smoothing though, allowing it to still perform on saggy mains like jts mono-blocks.

EDIT:
Would half the 10K amp in 2 ohm monoblock form weigh about 32kg !?
What would price be ?
Exciting... :lol:

Lev,

The new version will incorporate lightwieght and all the features you have mentioned 4X speakons[if 2ohms model only], 20Hz sinewave ready, 1.5 X SMPS rating of amp power. Better thermal headroom than this previous class-H.
We shall nick name this as Project Welder smiley20

But the price will touch one bar above due to overrated components and this is where people back off usually.

The current dual mono amp is about 52kgs, so single monoblock would be around 30kgs :lol:

Didn't you saw the bank of 36 X 18000MFD/65V caps........

Can you shed more light on ROOTs Pre-amp[read somewhere on the forum]

So Kanwar why is it when I suggested a mono block you said its not available but when Lev asked you said it was? Eh,Eh? :eh:
Just playing . One of the reasons I asked was I need an amp to power 4 scoops with plenty of headroom without breaking a sweat. Seems like alot of sound guys are after the same,i.e. an amp that can provide 4-5kw @2ohm and be totally stable and very low frequencies.
A Roots preamp is a mixer/eq/x over all in one unit which the prefered weapon of choice for Roots Reggae sound systems. The units provide the sound operator to tune the frequencies optimally for each tune played. The signal that comes out of these things can be dangerous especially the sub bass. This is why the amp has to be heavy duty.

Looks like a cool beast smiley1
what kind of output figures should we expect at 4/8 ohms? Does it have a PFC circuit?

lev why not see who would want the amp..... say 10 of you do, all chip in on one unit to get it over hear in the uk. then do your test etc to see if it is what you want and can handle the ruggers of a roots system, then order 9 in........... That way your on to a win win, if its not up to the job, its not a big £ loss divided by 10 people, if it is what you want then great order 9 more. Or get one yourself and see if you can be the uk distributor....... with your contacts could be a double win win smiley2

5kw @ 2ohms

2.7kw @ 4ohms

1.4kw @ 8ohms


This is toroidal transformer based, it doesn't have PFC.

Thanxz for telling me about the roots preamp thingy. I would love to hear one, if its truly remarkable in giving extended low frequency.

Lets make a deal,

Pay the shipping expenses-> If amp is OK after listening tests conducted by you guys , then buy it and book further orders, if amp is not OK upto your satisfaction, return it back...............


what say..........
