Hej,
Baserad på erfarenheterna från ”state of the art” phonosteget PHA-100 har Dynavector nu även lanserad ett mindre phonosteg P-75. Det är entusiastprestanda till budgetpris.
Den fungerar som ett standard phonosteg för high eller low output MC, MM samt som phono enhancer där ingångskänslighet och förstärkning bestäms av pickupens interna resistans. Inställningar görs vid att flytta på ”jumprar” inuti steget.
Info:
P-75 has a unique power supply that runs 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 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. There are no input or output coupling capacitors in the P-75 signal path.
The P-75 incorporates the unique current amplifier invented by Dr. Tominari of Dynavecor Systems Ltd. Japan, celled the phono enhancer.
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.
Investering: 5 800.- SEK
Mvh, robban
