Namec 1000 watt

[shinoby]

How do you think about this amplifier?
you can find it here

but this is a closed group

 

[nano nano]

wow good job 1000wat true power can go out 1000wat

 

[Joiker]

Wowww...amazing...

I see her wearing 65vdc = 45 vac, and using 4 pairs tr finals, how to get 1000 watt output?

sorry my bad english

 

[AudioSan]

1000W output with +/-65V rails???
realistic power: 225Wrms at 8ohm. 400Wrms at 4ohm.
bridged you can get 800Wrms at 8ohm any lower impedance demands a lot of outputs.

 

[shinoby]

I took it out of their group, as they are a group of very excited, PA is claimed to be capable of 1000 watts to 2500 watts in bridged mode

 

[AudioSan]

i can claim that i have a 1000W amp running on +/-30V. but that don't make it true
fantasy power and realistic power is not the same
realistic power for this amp is:
60*0.707=42.4Vrms.
42.4*42.4/8ohm=224.7Wrms

Not 1000W, lousy VAS transistors, lousy bias scheme, lousy drivers.

 

[nano nano]

might be 1000wat PMPO

 

[tinitus]

.... +/-65V rails???
realistic power........ 400Wrms at 4ohm.

maybe even a 4ohm load would close it down if pushed hard ?

might be 1000wat PMPO

Pretty Meaningless Power Output

 

[v3 jawa]

i thinks,, namec just a joke if can out 1kw RMS ,,

Pretty Meaningless Power Output

what do you mean meaningless? Marketing types love it.

 

[JOHN BALI]

maybe even a 4ohm load would close it down if pushed hard ?

Nah, ... maybe it can be done

How to make it real 500Wrms at 4 ohm?
Can we modified it?

So we can call it 1000Wrms stereo

 

[jaycee]

What I dont get is that if you can get Sanken output transistors, presumably the MT-200 types, why on earth would you not be able to get better driver transistors than TIP41/2? VAS stage is another matter but even the MJE340/350 would work well here. And why diode biasing?

 

[mcd99]

It looks like a subwoofer amp to me. Everything looks crude.

Then for that sort of output power would a triple EF not be a good idea?

 

[brig001]

More seriously, would you want to operate an amplifier of that power with no protection against DC, short circuits etc. Wouldn't plug my speakers into it.

stupid PA, i would rather to built BA1200 by APEX

 

[ragil]

there power amplifier made in. indonesian
