Hpa Electronic A2400

(Originally written by chte2b/translated from Audiofanzine FR)
Hi,

I'm the owner of a QSC PLX230 and a QSC PLX236.

I sent them in for service (maintenance needed) after nearly 3 years of use without problems...

Let's go back to the HPA.

My dealer suggested me two amps to replace them, an A2400 for my Turbosounds and an A5000 for my MP218 subwoofers.

I'm not a pro, it's only a hobby for me.

I often read specialized magazines and the A5000 and A3200 got very positive reviews.

I also read some forums and, of course, audiofanzine... positive and negative reviews...

But I like to try out by myself.

I'm positively surprised: big, even huge power... The sound is powerful and clear.

The low-end is present, the mids are pleasant, and the highs a bit too aggressive...

I wonder if they'll survive a whole night at full power?

No problems...

Although I prefer the sound of my QSCs, I must say that the HPA amps sound amazing considering the price... They are nearly four times cheaper than my A2400...

A major turnoff is their weight!!! 110 lb together!!!

Wrapping it up, this amp works fine and has an interesting value for money.

DCID here I am to put my opinion on the A2400 and A5000 hpa as the A5000 seemed so bad that I thought a default.

So we find a russi hpa A2400 test.

The weight of twenty pounds is still cooling of the rail as the A5000.

The electronic circuit is for the PCB as A5000.

The component could not be nothing to test because resoldered (t was taken aback)

Dynamometer under 4Ω First, the amp has released 650w 1% THD. Announcement 750w cell makes us 86%.
The new thing was to test the amp for a long PERIOD limit the clip. APRS is the 5 minute ad Premire rduire gain because the amplifier was put into protective cell reveals a bad light power. Thereafter the gain must be constantly Reduces not to cut the tracks. The temprature of the indoor amp does not take lack of hardware.

The protections are like the A5000 and not being protected in any way the transducers.

The test is does it cost to come to a blind, two other people to listen, on a speaker. 4 amp will be the cost: the hpa a.2400, an EV P1200, P2000 EV and an old amp Dune (sub-brand of Chinese AudioPhony) which has only one way that works.
Of course the EV's are to the same lev is more power and bass are Submitted, but the hpa and dune is difficult dpartag, the grave is behind the ANSI m dium despite the jump in the EV suprieur hp yet. A high level, equivalent to 2 amp, the dune begins emmetre of grsillement and goes into protection. Probably limit the power of one-half hpa A2400.
The ratio quality price is bad for me because the dune is an amp that costs 150 and not even the 400 hpa A2400. DB Technology has released a range of amp named HPA, not to be confused with the brand hpa, the HPA1400 is as powerful on paper and less expensive than the hpa a.2400, making it a good alternative.
Unfortunately I could not test everything the way I wanted. So I opened all test with power amp 1000w 500 to any brand.

I use this amp for 3 years now without any worries with chilton GC 152.
The whole gives a very clear result, both in acute than in the bass. I did not try many other amps, but listening to the sound it worth it "upscale."
The only downside is the noise a little disturbing breakdown in repeated when there is dead silence, but there is little attention as soon as we start to send the decibel ^ ^.
The value for money is very attractive.
In hindsight I would do this choice without hesitation. May be taken in the range (A2800) above for not pushing the amp too outside.
