Margules Audio Magenta FZ247DB Phono Preamplifier ( MM )
This high-end Phono Stage Preamplifier was handcrafted with materials and components of the highest quality, observing the strictest production processes and taking care of the smallest detail.
Following our manufacturing philosophy, the FZ47DB Phono Stage Preamplifier ensures a clear reproduction of the music captured on your precious vinyl records, only comparable to the very intention of the musician that created it, offering to all music lovers a realistic sound rich in details, with an unrivaled frequency response and a precise and organic harmonic reproduction free of distortion.
With the addition of the FZ47DB Phono Stage Preamplifier to your audio system, you will be able to enjoy a captivating, engaging and natural sound: the formula of Casa Margules’ characteristic sound.
The FZ47DB is conceived as a high-end solution to take full advantage of the high resolution offered by modern phono cartridges, as well as the capabilities of the most advanced turntables found today.
Dual Shunt Regulated Power Supply
By not having a control loop circuit, the Dual Shunt regulated power supply avoids the induction of non-desired harmonics and provides a high noise rejection, thus ensuring the quality of the audio signal.
Zero Negative Feedback
The philosophy that frames the FZ47DB circuit topology is based on always avoiding the use of negative feedback, a common practice that results in a loss of detail and sound richness.
In the same way, the RIAA (Recording Industry Association of America) equalization performed by the FZ47DB is passive, with multiple amplification stages to maintain the harmonic structure.
The FZ47DB offers great flexibility to be adapted to most modern phono cartridges, thanks to the incorporation of an internal DIP switchboard that allows to change the load with 16 different input impedances that vary from 27K to 390K Ohms.
To complement the design effort of the FZ47DB and increase its capabilities, we have incorporated to its manufacturing precision metal-film resistors, polypropylene audio-grade capacitors and gold-plated connectors.
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.
