The RoXdon
EDISON Transformer Preamplifier is a passive stereo preamplifier
utilising Step-up transformers to achieve gain together with audio isolation to
prevent earth loops.
The
RoXdon EDISON is a hand built hardwired (no internal connectors or PCB's) passive
transformer audio unit
featuring left & right inputs & outputs via 1/4" TS jack
and RCA phono connections all housed in a diecast alluminium enclosure providing
comprehensive electrical shielding. A high quality audiophile
grade potentiometer is used for output attenuation adjustment via a Marconi style
blue control knob.
The
two heavy duty custom made Z11 Iron Core Transformers have matched
parameters to ensure that the left and right sounds are balanced and
coordinated. These transformers impart warm sounding harmonics and
subtle coloration as found in vintage analog sound equipment.
