Dynavector P-75
phono pre-amplifier
& phono enhancer
instructions & specifications
The P-75 has a unique power supply that runs at over 1/4MHz.
It takes the low grade single voltage DC supply from the ac
adapter and converts it to the dual high voltages required for true
professional quality audio reproduction. The operating frequency
is over 12 times higher than the top of the audio band and it
incorporates super low noise wideband regulators in its output
stage to give ultra low noise supply rails.
The internal P-75 power supply is totally self contained and stores
many times the maximum possible energy requirements for the
phono amplifiers. This means that the quality or size of the external
ac adaptor is irrelevant. Increasing the capacity of the external
supply will make no difference to the quality of the sound.
The P-75 incorporates the unique current amplifier invented by
Dr Tominari of Dynavector Systems Ltd., Japan, called a Phono
Enhancer.
Note: The P-75 supply requires a higher peak current to start up
and so we do not recommend using an adaptor of less than
500mA.
The P-75 does not have any mains frequency or other low
frequency components in the power supply and so hum problems
that plague conventional phono amplifiers are eliminated.
An earth terminal is provided on the rear panel that will allow the
metal chassis to be connected to earth if required.
While the P-75 itself does not generate any hum, the tone arm
and interconnect cables may act as antennae and pick-up some
hum. This is normally removed by running an earth wire to the
pre amplifier ground.
In some applications, the P-75 may need to be earthed.
