Talking about unfair comparison is irrelevant. Comparing amps in gigs, playing music, is real world stuff.

Back on Topic, sure Andy's amps, would look more respectful in racks, than orange and grey suited Berrys..


The thermal limiting is very good in PKNs, unlike others... it pulls down average signal in multiple steps effectively saving voice coils from overheating. When *normally* used thermal limiter is never activated ok XE6000, even above 36°C.
The difference between XE6000 an INUKE is just 3-6dB and so called sound quality + few other things, which is apparently not so important here...
Finally what is "preamp" (??) I still do not understand..

Viktor, they use this so caller preamps (basically a hyped eq unit) and boost like 10db at 40hz on 1500W amp that is pushing 800W speaker. So by that supporting the local recone center. :-)
At least that is how i think it works.
So nothing any "normal" user would ever do.

You need to look at the pre-amp section of Roots & Culture to understand the concept LOL

Thanks, I will study it.

In the European *standard* signal chain we do not have such element "preamp"

Source signal usually originated from the output of FOH console, directly to the DSP (LAKE..) then routed to the amps with minimal correction. 10dB or so is such an invasive it would signal fundamental design fault of the system

Well it puts me in a quandary. I have what seems to be a sick 5002vz. If it goes to an engineer it'll be 50£ just to poke around. If it needs anything major add more £££. You see where Im heading. Even if amp gets repaired,
its 20 odd year old, so at risk of more problems. I would deffo consider what AK is offering. Mind you, if an inf8 came by....

these guys aren't into PA though viktor. they're custom building stuff to play their roots reggae music, and they're not looking to provide service to other users with their equipment.

they build it like a musician.

Reggae systems were traditionally custom built because equipment off the shelf wasn't capable of delivering what was being demanded by the sound man. Hence legendary folk who built absolutely massive amplifiers.
Too easy these days...

As said above, these systems are for one type of music (generally) and are owned/run in a way not seen outside of that scene. The systems sometimes play against each other, being judged on many things. The systems are run a bit like a musical instrument and the pre-amp is key. Put simply it's a way of boosting and reducing frequencies, much like a graphic but with carefully chosen frequencies. "Sound man" can boost sub in such a way as to excite the crowd, the music is geared to this. There can also be other effects.
When playing early house music we would sometimes drop the bass out for a few bars than bang it back in, you must have witnessed that Viktor? Same principal but taken to another level, not just the sub either.  Hope this helps?

If you bought your Crown MA 5002vz brand new 20 years ago, it should have paid for itself by now. If you purchased the Crown MA 5002vz used recently, and it is malfunctioning, that is the risk you take when purchasing a used amplifier. Only you can decide if it is worth servicing or not.   

I bought my Crown MA 5000vz amplifiers brand new when they were in production. To this day, all six Crown MA 5000vz amplifiers are working properly. When you invest in an amplifier, it will last for decades. 

Inexpensive amplifiers do not retain value on the used market once they are no longer in production. At least you can get £££ for a malfunctioning 20 year old Crown MA 5002vz. The same cannot be said for an amplifier that offers a retail price of £260.00 brand new in the box, when it is no longer in production more so malfunctioning. 

Best Regards,

Scarily close to the truth in some cases...

There is a soundsystem i know in hungary, Viktor, its called Dubapest Hi-Fi, and they're using a custom preamp, i think they play quite often in the capital.
The sound is well built and they're using pro drivers and amps, It should give you an idea, so worth checking out
