The F 360 is high performance
remote controlled Vacuum Tube Hybrid Preamplifier with a flexible electronic approach to
solving multiple issues of buffering the signal, controlling high and
low frequencies, focusing or expanding your 3 dimensional image, and
rear outputs for the option of creating an analog surround system.
letter F in the F 360 is in honor of the designer, Jim Fosgate (“Foz”).
Foz’s electronic design experience and excellence spans decades and
coupled with Jolida’s decades of manufacturing experience, results in a
unit which can provide our client’s with excellent sound reproduction at
a price far below what the competition offers.
The F360 offers both XLR
and RCA inputs and outputs as well as outputs for a mono or stereo
subwoofer. It also has a full tape loop for external components or a
legacy tape deck. And for those who want to go even further there is a
set of outputs for rear stereo speakers.
has used an upgrade to the classic Cascode circuit design and added a
MOSFET to give the musical performance of tubes with the speed and
detail of current solid state designs. Unlike most tube equipment it can
product a perfect square wave and uses zero negative feedback when the
tone controls are off.
