Magenta ARCH-3 Hybrid Integrated Amplifier

Categories: , , ,

Description

The ACRH-3 is an integral system that uses tubes on its preamplification stage and high-quality semi-conductors on its output stage, thus achieving a warm and detailed sound, with the necessary power to handle low-efficiency or less sensitive speakers.

At the same time, it incorporates a high-quality phono stage, conceived for those who love analog music and appreciate realistic and dynamic acoustic scenarios.

 

CLASS-AB+ OPERATION

The design of the ACRH-3’s amplification stage is one of direct coupling and discrete semiconductors that operate in AB+ configuration, which allows it to optimize the junction between stages, avoiding signal loss.

 

TUBE PREAMPLIFICATION STAGE

The preamplification stage is based on a design that uses two double-triode small-signal tubes (one per channel). It also has regulated power supplies, both for the filament and for the high voltage of the tubes, ensuring a very low level of noise and avoiding microphonics, which provides to musical reproduction a feeling of warmth and instrumental richness.

 

CONNECTIVITY

Line Level Inputs: The ACRH-3 has four different RCA unbalanced inputs suitable for connecting line level devices such as CD players, tuners, tape players, turntables with built-in phono stage or an external phono stage preamplifier.

 

Phono Input: The built-in phono stage preamplifier is of high quality and totally discrete, with a gain that allows its compatibility with moving magnet, moving iron or high output moving coil phono cartridges.

 

Amplifier Input: The factory setting of the ACRH-3 provides an unbalanced RCA amplifier input, which is connected to the preamplifier output (PRE OUT 1) by means of a bridge or jumper that can be removed in order to connect a different amplifier or sound processor.

 

Preamplifier Output: The design of the preamplification stage allows an additional output (PRE OUT 2), which may be used for the connection of an active subwoofer or, if so desired, another amplifier.

 

Line Level Output (Direct Output): The ACRH-3 has a line level output controlled by the input selector on the preamp stage that is not affected by the volume control (this output completely removes the volume control from the signal path). This output can be used to connect a recording device, send the audio signal to another area, or to connect the equipment to a surround sound processor, thus giving you the flexibility to integrate your high-performance stereo system into your home theater system.

 

Electrical output: The ACRH-3 has an electrical output with a maximum capacity of 15A / 1,800W (controlled by turning on the equipment). This output is designed to be connected to the Magenta QR2 Noise Line Suppressor. This allows you to centrally turn on the audio components connected to the switched filters by polarizing the ACRH-3’s AC output.

 

NEURO-ACOUSTIC ALIGNMENT (ANA®)

The ANA® technology (Neuro-Acoustic Alignment) is one of Margules’ technological innovations developed from a fundamental principle: the human brain perceives sound by prioritizing the harmonic structure above fundamental tone; that is, it focuses on how humans perceive sound and not on how we measure it.

This technological advance originates from the engaging sound theory and is based on the way in which our brain decodes the information from the sound waves through the ears: when sounds are closer, they keep us focused due to the relation between perception and sound, the distance at which we perceive them and their intelligibility, whereas distant sounds, even when intelligible, do not catch our attention and are easily ignored.

Our ANA® technology is designed to achieve a realistic sound, with a wide frequency response, low distortion and precise harmonic reproduction, optimizing to the utmost the relationship between the source and the receiver, so that you can enjoy your music in a way you have never experienced before.

Margules Audio

Our Story More than 90 years of history implementing out technology with special attention to the innovation and design. Today the fourth generation of engineers and craftsman are devoted to challenge the boundaries of audio reproduction. Each piece of our catalog is handcrafted to implement our innovation with chosen components to achieve our specific design philosophy, ANA® ( Acoustic Neurologic Alignment ), focused in how we as humans process and perceive sound, prioritizing the harmonic structure over the fundamental tone. Our efforts, knowledge and talent are focused in the design and manufacture of High-Performance audio equipment with our own technologic proposal to bring unsurpassed audio experience. Thanks to our innovative technology and the sound reproduction quality, Margules® is today a World reference in the high-end industry. MARGULES ® is also interested in creating sound oasis, making integral sound projects that generate captive and enriching audio experience in different spaces. 1925 In the Early twentieth of 20th century A Rumor is heard by a young European engineer, Mexican President, Plutarco Elias Calles is inviting capable man to participate in the National Electrification Plan. Jacob Margules sees this as an opportunity and an ideal pretext to construct a new life on America. Jacob asks for a loan to his father-in-law and crosses the Atlantic along with his wife, his dreams and capabilities. 1927 His talent as an engineer is rapidly recognized in Mexican land and plays an important roll in the first national radio stations. In this country our name has been link to the sound reproduction since its origins. Rapidly acquires the needed expertise to step up and found a store called Emporio Electronico, focused on selling and supporting the new radio industry. In a short time is the gathering oasis of the aficionados and professionals of the radio enthusiast, later turns in to Casa Margules. 1954 As a result of the success obtained in Casa Margules the business grows in to two, the distributing company, Radio Surtidora, and the manufacturing branch, Tel Rad, where we can find the born of our legacy, is here where we started manufacturing reproduction instruments, gramophones, turntables, amplifiers and speakers. When High Fidelity begins to be possible, the Brand Marvox was created, under that brand where produced several Amplifiers, Speakers etc. Tel Rad and Marvox project was headed by Alejandro Margules, second generation on the company. 1981 The accumulated experience and knowledge  thru does day and the new generation brings new ideas: Julian Margules, grandson of Jacob Margules and son of Alexander Margules, has the vision to use this baggage to implement his own ideas, the Magenta line is born, first as an high performance biamplified active system . 1990 After years of RD, Julian Manage to bring together his Ideas and experience in a project that became an Icon: The U-280 , the first servo controlled full class A amplifier with no need for any type of adjustments an unprecedented thermal efficiency. The U280 has been awarded throw the decades by the specialized critics and press, The U280 always has been in continuous evolution. Due unique characteristics  is a worldwide reference in the High End  Audio. Today, Margules, continuous working with the same passion in new technologies to reproduce the music with a natural and reach sound and exclusive aesthetics. Our Mission is clear: give the deserved place to your music and space where you listen, so you can enjoy it at its best. 2004 Margules makes the first high End iPod interphase, the “I-end” with one of the first electrostatic tactile panels in the market, video feedback, fully remote control throw RS232 o IR, and converted any I-pod in a music server with a high quality audio characteristics. In 2006 Sterephile reports over it and 2007 In the CES at Vegas is consider by NBC  news as a high light at the show. It was develop around our Analog to Digital Enhancer ADE, that has been mention by StereoPhile as a killer product and received awards by many other publications. 2018 Thanks to the growing demand on our product, and a continuous quality improvement requirement, the factory was relocated at a bigger and very well-organized facility.
