Quartorigo – Musical Rhapsody Meets Sublime Style
An astute electronics genius heralding from the unmistakable landscape of Macerata's countryside in Italy; Quartorigo lives by a philosophy that sees superb design the centre-point of refined technical expertise and innovation. Today Quartorigo leads the car audio industry with it's delectable aural solutions, stylistic flow and methodological ingenuity. Constantly redefining the benchmark for tomorrow's car audio and raising the bar to levels many companies simply will never achieve. Such is the Quartorigo way.

Humble Beginnings
A garage, a common passion, a crew of courageous enthusiasts. This is how most great musical adventures commence. However in this instance we're not talking guitars and microphones to arouse souls and blaze, but resistances, transistors, soldering and and most of all the limitless will to create something beautiful. During the eighties the high-end car audio market needed something new. Who'd have thought it would come from here, amongst Macerata's picturesque hills; dreamy car audio products set not only to become benchmarks, but also products able to please music lovers unquestionably.

Opus Series – Articulation Beyond Amazement
Not everyone is looking to be hammered into submission. On the contrary there’s an echelon of discerning audiophiles who desire supreme sound quality above all else. Copious amounts of clean power. Articulated deep bass, delectably controlled midrange and supremely accurate highs. Barriers are there to be broken, and budget is of secondary concern. This is the territory of Quartorigo's superb Opus range. Developed with every detail heavily scrutinised; this might well be as close to aural perfection and can be found on planet earth.

Design Ideologies
Music will always be the original soundtrack of our lives. For it’s the true creator of emotions and the incubator of dreams aplenty. It’s an irresistible force which cannot be pushed away, nor can one hide from it; for music is everywhere. It’s as intrinsic to life as is oxygen, and it accompanies us wherever we go.

Music And Culture
When talking Italians and music you’re talking about a long and prestigious tradition which has its foundations firmly rooted within centuries of unique theatre settings, thus ratifying the bond between music and culture in a way few other societies can. This is where Quartorigo draws its inspiration from. It’s work is aimed at the pursuit of theater sound quality excellence, but inside your vehicle. From a concert hall to your vehicle’s seats, without loosing a single note and allowing you to live out the same emotions. It’s what makes Quartorigo a real conductor seated next to you as you commute.

Alloy Artwork
Attention to detail means that appearance matters too. Like a sculpture, the Opus amplifier casings are created from a single block of aluminium; carved for hours via an extremely complex CNC machining process. This isn’t merely an eye-catching gimmick, for these chassis are designed and engineered in-house to provide the very best heat dissipation; thus allowing these units to reproduce performances which were hitherto unthinkable with other amplifiers.

Under That Hood
As music lovers, what really matters is whats under the metaphoric hood. Endless time has been spent testing the behaviour during interactions between several sets of components. Opus is the epitome of Quartorigo’s firm conviction that besides the electrical values and specs of components there is still a difference. Every capacitor, transistors, mosfet and even power transformer ferrite cores; one brand can be vastly different one from another. Combining the right components during testing and comparing all interactions amongst said components upon a circuit board is time consuming. But it’s a most rewarding task, the result being a true thoroughbred duo for music lovers par excellence. The Opus I for its detail given by a Class A polarization, and the Opus II for its balance and control on any load.

The Opus Difference
The sound these amplifiers produce will move you to such a point that you won’t want to finish listening to your music. Rest assured you’ll get a shiver along your back to accompany your listening.

Design Features
The rich heritage of this astute and masterful designer, together with its ever-increasing technical acumen; is conducive to these components featuring a vast array of impressive design ideologies and latest technological advancements. Below we expound some of them further.

Dual Mono Power
The Opus amplifiers feature two completely separated mono amplifiers, laid adjacently inside its unique chassis. The concept is simple; keep everything separate to provide a perfect stage and image and to preserve the sound signal going through the device.

Supplying The Power
The power supply and amplification stages are buffered with multiple large capacitors. Carefully selected components, along with a most precise component location thence combined with large and short signal tracks; form part of the secret of these powerful amplifiers’ quality.

Wireless Circuits
Featuring a straight circuital configuration, the sound signal path is completely wireless. Indeed the only wires used are for the protection LED module. This allows these amplifiers to output the timbre performance and spatial reconstruction of a live musical event.

Gold Plated Connectors
Speaker and power connectors, including the remote; are made from CNC machines brass blocks which go through a 24 K gold plating process to improve the electrical conductivity where the wires contact them.

Triple Protection
The Opus amplifiers are completely protected. Thermal protection prevents the amplifier from exceeding 95° C, in case of over-heating normal operations may continue only after a temperature decrease 10° C from the threshold. The Speaker protection is enabled if a MOSFET fails and the overload protection protects the amplifiers should they receive in incorrect impedance load.

What’s With Those Looks
The machined steps are designed to mimic a theater entrance stairs. Perfectly integrated and easily accessible screw holes for mounting the amplifier are inspired by the stairs at the entrance of the theater, as a prelude to a unique and fully immersive musical experience. The heat sink is designed to resemble the keys of a piano. The concert is about to begin and the excitement is growing. Lights on, curtains open, the amplifier heat sink is already hot, the piano is waiting on the stage!

100% Made In Italy
All Opus amplifiers wear the internationally recognized 100% Made in Italy certification. This guarantees Italian origin from the initial idea, through development and design; onto production and final completion in Italian territories. This ensures a guarantee of high quality, precise workmanship and original design. High demands are also met by working conditions in production and final testing of products. Each of the two Opus amplifiers is subjected to a stress test after assembly, when it is connected to the pink noise generator at the input and resistance load at full power at the output for six hours. The listening test is also followed, and at this stage the amplifier is connected directly to the speakers and plays music for another six hours. Even the slightest glitch or deviation will not escape thorough testing. The result is high-quality products that you can rely on for years to come.

A Post Script Made By Time
Just to finish all us to leave you with this. Experience is acquired with time and enduring challenges are conquered day after day. Quartorigo systems, like all boutique products; evolve with time but last for life. The company designs and builds it's aural instruments to not only last but prove themselves time after time, list after listen and year after year…
