CHARACTERISTICS
The idea of creating the FZ47DB Phono Stage
Preamplifier originated from the need of music lovers to
satisfy their passion for analog music, since they
constantly face the absence or poor quality of a phono
stage in most modern preamplifiers, integrated
amplifiers and audio receivers.
In addition, 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.
In this way, the FZ47DB provides an incomparable
listening experience, effortlessly creating holographic
sound scenarios that astound due to their exceptional
clarity, detail, smoothness, fluidity and tonal response,
even during the most demanding musical passages.
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.
PASSIVE EQUALIZATION
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.
FLEXIBILITY
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.
HIGH-QUALITY MATERIALS
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
â
)
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.
