Περιγραφή

Rega Fono MM MK4

Το Fono MC MK4 είναι ένα εξαιρετικά υψηλής ποιότητας MC phono stage σχεδιασμένο να μεγιστοποιεί τις δυνατότητες οποιαδήποτε κεφαλής MC χαμηλής εξόδου. Αν και ο προενισχυτής κεφαλής Rega Fono MM MK4 είναι σχεδιασμένος για την σειρά των κεφαλών MC Rega, είναι εξαιρετικά ευέλικτος και εύκολος να προσαρμοστεί σε κάθε κεφαλή χαμηλής εξόδου με δυνατότητα να ρυθμίσετε τόσο το κέρδος όσο και την αντίσταση ανάλογα την κεφαλή μέσω των dip switches που είναι βολικά τοποθετημένα στο πίσω μέρος της συσκευής.

• The Rega Fono MC MK4 has been designed to be effective, easy to use, and above all, to reproduce music. The Fono MC MK4 uses the Linear Systems low noise LSK389 FET in an all discrete input stage where low noise and linearity are vitally important to get the best from an MC cartridge. Because of the high input impedance of FET, the loading effects of the amplifier circuit are minuscule and do not affect the performance of the cartridge.
• KEY FEATURES
  Dedicated moving coil phono stage
  Simple connectivity and operation
  Fully adjustable via DIP switches via rear panel
  MUSE operational amplifier used in RIAA equalization amplifer
  Two selectable gain settings
  Default factory settings matched for all Rega MC models
  Latest design custom casework
  Lifetime warranty against manufacture defects
• A MUSE operational amplifier is used in the RIAA equalization amplifier. Polypropylene capacitors have been used in the signal path and in the RIAA equalization circuits. There is selectable input loading for both resistance and capacitance along with two different gain settings located on the back panel making the Fono MC MK4 compatible with most low output MC cartridges. The new Fono MC MK4 circuit resulted from the development work carried out on the hugely successful Aria phono amplifier.
• The aesthetic design of the Fono MC MK4 was as important as the quality of its electrical capabilities, so it benefits from the same new aluminium case as the Rega Neo MK2 PSU and Fono MM MK5 phono stage, giving it a design which offers a familiar feel and moreover brings it in line with its illustrious bigger brothers.
