Naturalness is the Culmination of All Masterly Skill

Sound. Beauty. Gracefulness. Naturalness. Not less. And not more. In order to achieve all that, Berendsen has
uncompromisingly devoted itself to a number of principles: Focus on the essential. Smartest technology.
Manufacture largely by hand and in small numbers at one time. And: Components by Berendsen are built to
last. The manufacture of ever-changing products, the new ones differing from their predecessors only by
marginal characteristics, is not the concept pursued by Berendsen. Anybody who wishes to upgrade his
Berendsen components after a while, has the possibility to retrofit his components by Berendsen even years
after purchase.

The Berendsen Preamplifier and Power Amplifier

Sometimes it takes two to achieve the one thing: Maximum pleasure.
PRE 1. Preamplifier. No capacitors in the signal path. A sound reproduction whose naturalness impresses.
Precise operational amplifiers. Discrete output driver configuration in single-ended class-A mode.
STA 150. Power amplifier. Generously designed toroidal-core transformer. High current filter capacitors.
DC-coupled. Manually-selected power transistors. Wide frequency range. Complex protective system.
The result? Something very simple: Extraordinary sound.

Berendsen CD-Players

CD-players by Berendsen allow the acoustic reproduction of even the most subtle sound differences. The
cd-mechanism, control and converter board rest on daming elements and are thus decoupled. Analog and
digital electronics are fed by separate power supplies. The energy is supplied by 30 VA toroidal-core transfor­mers, the operation of the digital-to-analog converters is based on the Delta-Sigma principle. All elements
have been thoroughly selected with regard to sound-affecting parameters. On top of that: A manufacturing
method that makes our products sturdy and durable. That makes the beauty of sound not a momentary
pleasure, but a lasting experience.

Berendsen Integrated Amplifier

People talk about it. They praise its sound quality. They commend its craftsmanship. But they are neither
referring to the bells of Notre Dame nor to the masterpiece of a saddler.
When discussing differences in sound quality, it is sometimes just a step from ordinary commercial quality
to a distinguished individual style. The Integrated Amplifier IPA 80 is available at a price level which is attrac­tive, but where exceptionality and superior quality are hard to be found. This is where a genuine product by
Berendsen makes a difference. Behind a 10mm face of scotched aluminum is concealed a technology of
superior quality and refinement. Three toroidal-core transformers guarantee optimal energy flow. Four
noble Aerovox electrolytic capacitors stand for smooth supply. Six ring emitter transistors per channel pro­vide the power output stage with power and render it autonomous. Microprocessor control allows pre-level
adjustment for every input as well as smooth setback and raising when changing over to another input. The
result is, generally speaking, something very exceptional.

It is the perfection of natural sound that has motivated Berendsen for over ten years to design and produce top class audio-components.

Berendsen Phono Stages

If you are staying where the air becomes rare, where ‘the higher‘ and ‘ the highest‘ are weighed against each
other, you will sooner or later discover the keyword: Analog.
Berendsen Phono Stages have uncompromisingly been designed for the purpose of analog reproduction, for
the most natural form of signal processing.
PPR II. The all-round phono stage. Switchable for MM/MC. Separate regulated power supply. Gain through
precision operational amplifiers. Passive RIAA-Deemphasis. Change-over of gain and input impedance by
means of Dip-switches.
Analog One. Phono preamplifier stage as the ideal supplement for turntables in the high-price range. Fully
discrete construction featuring single-ended class-A technology. Analog One meets the requirements that
allow us to make full use of all the possibilities offered by phono components of superior quality.

PPR II

Berendsen Signal Cable

You cannot win. But lose a lot. The sound quality of individual audio-components cannot be improved by
means of cables. However, inadequate cables can reduce the quality of sound considerably.
Signal and mains cables by Berendsen have been thoroughly designed to produce an overall sound that is
absolutely natural. It goes without saying that they constitute the optimal configuration among Berendsen
components.
Signal Cable Bluelink. Balanced Twisted-Pair design. Two internal conductors, consisting of massive pure
silver wires. Two-stage teflon or polyethylene insulation. Extremely tight shield mesh. Plugs fabricated with
lead-free solder tin containing a high portion of silver.
Mains Cable Powerlink. Internal conductors made of high-quality electrolytic copper. Excellent high-frequency
attenuation due to a special coating applied to the internal conductors.
Berendsen offers you the choice between two different profile sections: 3 x 1.5mm2 and 3 x 2.5mm2.

Berendsen Special Edition

What exactly is meant by “Berendsen Special Edition”? The preamplifier and power amplifier combination
STA 150 and PRE 1 were the initial products on the basis of which a Special Edition was designed later on.
No doubt, there will always be a Special Edition of a certain component in the future. It is important to know,
however, that “Special Edition” is not a term implying some sort of craze for fancy designs, but a term which
is used for the raise of a basic component to a higher technical class.
Anybody who feels a desire for more technical refinement after a while, but sees himself confronted with the
proverbial longevity of any Berendsen product, has the possibility to upgrade his components – even years
later – to the Special Edition level. This concept is not only sensible, but has also proven very successful. And
it would mean the continuation of a wonderful friendship.
