Information On Lundahl I/O Transformers
Transformers have a pleasant sound characteristic, especially the low 
end sounds rounder and more full-bodied. The top end benefits from a 
softer and silky atmosphere without being emphasized. 
Further  advantages  are aspects  of  improved  operational safety:  gal-
vanic  insulation  excludes  the  transmission  of  damaging  currents. 
Electromagnetic, high frequency or digital interferences have no influ-
ence on the signal quality, hum potentials are cancelled out.
From  our listening  experience  we  can recommend  Lundahl  I/O trans-
formers in any case, and their improved operational safety is an advan-
tage that can not be overestimated in any critical or complex studio, 
broadcast or sound reinforcement installation.
