Dynavector PHA100 phono head amplifier Manuel d'utilisateur télécharger pdf

The Dynavector phono head amplifier PHA-100 is a complete redesign of our original head amplifier the PE-1, using new

circuitry and the most advanced and highest quality IC’s, resistors and capacitors currently available.

The PE-1 was designed more than 15 years ago using an entirely new patented circuit. During the development of the highly

acclaimed XV-1 cartridge, its performance was optimised through the use of

the original PE-1, making it superior to any other cartridge available.To build

on this, we decided to redesign the PE-1 with the specific aim of making it the

most advanced head amplifier available for the new cartridge. The result is

that the performance of the PE-1 has been significantly improved following

intensive design work and after comparing many prototypes using alternative

components. The result is the PHA-100.

Important factors in reproducing music such as the preservation of natural

ambience, a wide dynamic range and harmonic fidelity are easily overlooked

by conventional methods of amplifying the signal of the cartridge’s output

voltage.There is no shortage of expensive head amplifiers and step up transformers for MC cartridges on the market, all of

which have the aim of amplifying the very low output voltage of MC cartridges with the highest fidelity

In the PHA-100 the maximum current is taken from the cartridge by an active electronic circuit. This current is then

converted to a voltage sufficient to drive a conventional preamplifier For the PHA-100, the current sensitivity of the cartridge

is the most important consideration. By using current amplification, the magnetic distortion of MC cartridges is significantly

reduced but the S/N ratio was still a problem when the PHA 100 was designed 15 years ago. Today, thanks to the latest

technology and components, very low noise operational amplifiers are available and the S/N problem of head amplifiers has

been solved.

 The PHA-100 has an impedance selection switch to provide the correct match for either low or medium

impedance MC cartridges. In this way, users are able to get the best sound from their cartridge.

 The PHA-100 makes use of a unique patented circuit designed to provide the maximum fidelity from vinyl

sources.

 Dynavector is proud of its long record of innovation in the hi-fi field. Our DV-DRT XV-1 cartridge, DV-PHA-

100 head amplifier and DV SuperStereo processors are our answer to a digital industry threatening to destroy

much of the great recorded musical heritage of the last century.
