dounino's review (This content has been automatically translated from French)

How long have you use it?

I use the amp for 6 discomobile benefits in very diversent. I use most often with the potentiometer at half power for small rooms (100 people) if not for the exterrieur it's great, I put the music during a fireworks display and the power of the amp allowed me to be heard despite the Rafuse of the fireworks and crowds. I useful in Parallel with 4 ohms on each channel, a subwoofer 800 w SAR and an enclosure Berhinger B1250 pro 800w.

- What is so special that you like most and least?

The pros: light weight, small size, depth, power, very low background noise, sound quality (even the sound clip is not saturated). it seems that the amp can still give more.
the -: no possiblilité bridgeage on this model.

- Have you tried many other models before buying it?

I had some low-end amp 2x 200w amp and also good interM630 2x300W into 4 ohms but the QSC is over.

- How would you rate the quality / price?
Look carefully you can find a great price for an amp of this quality

- With experience, you do again this choice? ...

Yes, it's always a delight to find the Grail. then yes I would do this choice j'usqu'a beat if it exists!

9 I vote because as my French teacher perfection does not exist and because we can not the Bridger amplifiers.

dialoire's review (This content has been automatically translated from French)" Pleasantly surprised"

I just bought this amp QSC plx 1804 to replace my old 1800 receiver Bose over 25 years and who had failed on an outing. Having taken years like him, there was no question of repair, his weight had become a major handicap (+35 kg fly). I hesitated a lot on the choice of model between 1804 and 1802. The light weight of 1804 (5.9 Kg) left me thinking that maybe I would be remiss of power to feed my four Bose 802. Finally it is the weight criterion that motivated my choice to the model 1804. Eager to test in real condition, I could measure its performance at the sound of a conference of 300 people. Having heard many good things about this material, I confirm that other previous opinions by adding it combines all the advantages of a dream amp, weight, power, sound, compact. Its side, it's important I found it very clean without staining majeure, to make me forget my old Bose without regret. It remains of course to discover in more difficult conditions but already he has convinced me of its potential.
I can only influence positively the person whose choice is not fixed and would not know quality QSC PLX2.

* For how long have you been using it?
nearly 2 years and about 50 dates.
* What thing do you like most/least about it?
+ The power to weight ratio is really not bad, at least, lack an entry in jack and the bridge mode!
* Did you try many other models before getting this one?
I own the PLX3402 Series RMX, Yamaha. What I liked about these new models is the lightness and power. Parcontre contrary to what the other reviews said, I find it blows a lot, I use a pair of Nexo PS10, it blows a bit anyway. A little light on the vocals for me or you feel that the amp would have deserved a few watts. They announce 2x900W RMS into 4 ohms but the doc said that European products have up to 10% less because of radio interference standards.
* What is your opinion about the value for the price?
Very good, very reliable amp, light, and the mouth like much more modern than the PLX series1. Discreet ventilation. Heated moderately, like all QSC, but they heat it goes. Parcontre I have a Yamaha P4500, to warm on satellites is nearly impossible!

* Knowing what you know now, would you make the same choice? ...
I would leave on a model a little more powerful for my PS10 but otherwise it's a good amp!

A fireworks I had pushed a pair of 46 with a 3402 and a pair of 38cm with 1804 and we got good results!

I put 8 because there is still a notch below skuas and other Camco!
