Frankie hybrid preamplifier

Υβριδικός προενισχυτής Frankie
Η καρδιά του υβριδικού προενισχυτή Frankie, ο προενισχυτής γραμμής, αποτελείται από 4x 6DJ8 διπλοτρίοδες διαμορφωμένες ως ένα ισορροπημένο κύκλωμα SRPP. Το κύκλωμα, με μηδενική συνολική ανάδραση, επωφελείται από 4 ξεχωριστά και ρυθμιζόμενα τροφοδοτικά με διακριτά εξαρτήματα.

ΠΡΟΕΝΙΣΧΥΤΗΣ υβριδικός Tube-Fet. AIKIDO circuit design. Zero feedback.
PHONO MM/MC, full Balanced, discrete FET Cascode design.
Line 2x XLR – 1 x RCA – 1 x PHONO – Outputs XLR/RCA.
Shunt volume control with relay switched resistors. Android & IOS remote control App
& Infrared Remote control.

Frankie hybrid preamplifier
The beating heart of Frankie hybrid preamplifier, the line amplifier, consists of a 4x 6DJ8 double triode configured as a SRPP balanced circuitry with an active cascoded mosfet current sink.
The circuit, with zero averall feedback, benefits of 4 separate and regulated power supplies with discrete components.
The volume control is once again our “golden stairway”, the attenuator developed in house and used in all our products.
This attenuator, made up of fixed resistors switched by relays, has a precision and quality superior to common analogue or digital potentiometers.
In Frankie hybrid preamplifier, this attenuator works in “shunt mode”.
Phono input is a solid state circuit suitable for both MM and MC cartridges, it benefits from an ultra-low noise discrete FET input, a fully passive RIAA network and a balanced output.
The dip switches on the rear panel offer a wide range of capacitance and resistance adjustments for the cartridge interface.
Obviously the phono board has its own dedicated power supply.
The preamplifier can be controlled both via iOS & Android App or via infrared remote control at the same time.
Frankie hybrid preamplifier has been designed to be the ideal partner of the Frankie monoblock power amplifier.
