Pivetta Opera Only - Perhaps the most expensive audio amplifier in the world

Reading time: 2 minute

The most ideal amplifier in the world?

The world-renowned industrial designer Andrea Pivetta aims to design the most ideal amplifier in the world. The result is the Pivetta Opera Only amplifier.

This beast of amplifier pumps an outrageous power of 120.000 W, divided into six channels of 20.000 watts class A. Requires a power supply of 230 / 400V, 50/60 Hz, 450 Amp (400V).

With a height of over 2 m, a weight of 1500 kg and an impressive design, it looks more like a futuristic teleportation device than a power amplifier. Its beauty is matched only by specifications.

Pivetta Opera Only specifications

Here is a description from their site:

"This state-of-the-art amplifier, no doubt superb, has six 30 kW triple-insulated toroidal transformers, 16 1600V / 400A ceramic diodes, 216 Kendeil 6800uf 160 volt aluminum electrolytic capacitors, 2112 bipolar power transistors, 12 analog inputs (RCA / XLR) and 6 digital, 12 output channels and 192 speakON connections.It is capable of producing an amazing power of 120.000 W rms at 8 ohms (30 kW class A). 6 x 20.000 W rms or 12 x 10.000 W rms.

Other specifications:

  • distortion: THD + N 0,002%;
  • frequency response: 20 - 30.000 Hz;
  • S / N:> 115 dB (20 Hz - 20 kHz A-Weighted 8 ohm);
  • Input sensitivity: 11 dBu / gain 30 dB.

Looks like you might need some own power grid to power this amplifier, but if you spend 1.6 million Euros on an amplifier, you can probably afford the electricity bill.

In the construction of this applicator, some more special materials were used, such as: aeronautical quality aluminum and gold. Along with the manual assembly, its price was estimated at 1.6 million Euros.




    1. Not too much, even for a stadium it's too much. And the acoustics of space are hard to control with something like that.

      1. Well, why should it be hard? Place the speakers where you want them and control them with either an analog or digital audio mixer. If I'm not mistaken, the amplifier already has a tablet and integrated sw. This is seen in the first picture in the article.

        1. Pai misfortune that beside the speakers. And due to the speed of the sound, there will be nonsense between the sounds perceived from two speakers. Make a site sketch and you'll see for yourself.

  1. The supply is made directly from the Iron Gates 1 and 2 placed in parallel 😂 ..
    It has absolutely no applicability, or maybe just exposure like car amplifiers of tens of thousands of watts. I'll really find out how powerful it is at Untold or Tomorrowland.

  2. Overall, it is equipped with high power but with many amplifiers, with delay control circuits, etc. Arranged in space with acoustic adjustments. It's not like a wedding!

  3. At Tomorrowland, the sound is provided by a specialized company, of course, it doesn't matter who, but I use the following:
    - 66 pieces of LA12x 4x2600w 4ohmi;
    - 116 pieces LA8 of 4x1800w 4 ohms;
    - 7 4x4w 1000 ohm LA4x pieces XNUMX ohms;
    All with the possibility of use and at 2 ohms and all with universal SMPS with active PFC.
    From all this results a power of:
    LA12X> 171.000X4 = 686.400w;
    LA8> 208.800 × 4 = 834.400w;
    LA4X> 7000 × 4 = 28.000w;
    All 3 assemblies give somewhere at ~ 1.500.000 w of amplifiers but I don't think they are at their maximum
    Asta..this in 2016 ..

  4. That's good when you have a neighbor who dries you with manele, you put some Slayer. It works even if the neighbors are in the neighboring village.

        1. It is really only for professional use, it is very successful in more or less controlled demolition companies.

    1. If you look through the history of the radio you will see that there were radio stations with powers of 1000kW and over ... with tubes!

      1. In Bod, Brașov County, the transmitter had 2000 kw. Marconi himself witnessed the installation in 1933. The transmitter from Tancabesti near Bucharest had 1.5MW in the 90's. Neon people in the surroundings were lighting their houses, and some detected the sounds in various objects, pipes, fences.

          1. I think those with the houses around the antenna can tell a lot about these phenomena. But it's a thing of the past, now there is no AM but digital with low power around 250 kw, no analog vacuum tube ends are no more, they have been replaced with Harris systems with transistors, digitally. You can no longer 'hear' the music in the gutter of the house, because there is no more analog broadcast in AM. Some even sang metal jaws in their mouths.

          2. At that time, there were maps with optimal propagation directions (to which radio amateurs also contributed a lot) and they were also taken into account. Plus the "strategic" position!

  5. I'm a boar. I mean, I don't know. I quote: "In the construction of this applicator, some more special materials were used, such as: aeronautical quality aluminum and gold." With gold I have ideas where to put it. But why Al?

    1. I assume they used 6061 aluminum for high and fast thermal conductivity.
      The distinctive features of this alloy are: brightness, ductility, good toughness, abrasion resistance, corrosion and high stress.

  6. Well, I think very few individuals can afford that!
    And I think that there are even fewer places, apart from stadiums, airports or central stations where it can be installed and used at full capacity without violating the existing "anti-noise pollution" laws. I think it's done for the love of art.
