Dynavector PHA200 phono head amplifier Manuel d'utilisateur télécharger pdf

The Dynavector PHA-200 phono head amplier is a unique current amplier that offers the best performance for most

moving coil cartridges. The PHA-200 is a complete redesign of our PHA-100, using new circuitry and the

most advanced,

highest quality components.

The most unusual feature of the PHA-200 is its amplication

method. Conventional phono stages or step-up transformers

are designed to accurately amplify the very low output

voltage of moving coil cartridges. In contrast, the PHA-200

extracts the maximum current signal from the cartridge, and

then this current is converted into a voltage high enough to

drive a conventional line level pre-amplier.

In the PHA-200 the coil of the cartridge is short circuited or

terminated by zero ohms, consequently the current from the coil is much larger than with conventional voltage amplication.

All cartridges have magnetic distortion caused by nonlinear characteristics with in the magnetic materials of the cartridge

components. These distortions have an adverse affect on the sound quality.

By using current amplication and extracting the current signal, the magnetic distortion of the cartridge is signicantly

reduced. In other words the linearity across the reproducible frequency range for the cartridge is improved. As a result

PHA-200 is able to amplify the original cutting signal on records as precisely as possible.

The sonic advantages of the PHA-200 compared to conventional phono stages or step-up transformers is immediately

apparent. The neutral soundstage, rich mid-bass and smooth highs are most impressive. The overall sound quality offers

improved transparency and resolution.

A unique patented current maximizing circuit designed to provide maximum delity from vinyl LP's.

3 position input resistance selector to suit most MC cartridges.

Left and right channels are completely separated but have identical signal paths. This is achieved by

using mono-symmetric circuit design. The input selector switch is an extremely low contact resistance

type rated for minute currents. The switch has separate sections for each channel.

High-grade components are used. All components are carefully selected following repeated listening

tests.

Extra low noise stabilized power supply with high-grade, parallel connected, electrolytic capacitors in

the smoothing circuit.

An R-Core transformer that offers improved voltage regulation and reduced ux leakage is used.

The transformer has magnetic and electrostatic shields.
