ABOUT THE OUTPUT

The output impedance of the icOn TVC
follows a fairly complex pattern but the
worst case is basically present with no
attenuation. In this case the source im-
pedance and the copper losses solely
determine your output impedance. Thus
for a CD-Player with 200 Ohm output im-
pedance the worst case output imped-
ance after the icOn TVC is around 700
Ohm. For reference, the output imped-
ance of the popular Audible Illusions
Tube Preamp's line stage is 1200 Ohm.
The highly reviewed Conrad Johnson Pre-
mier 17LS line stage has around 850
Ohm output impedance.
With all transformers the ultimately real-
ised output bandwidth is very much sys-
tem and application dependent, but the
bandwidth limited icOn
TVC when driven from a su
ffi
ciently low
impedance (2kOhm or less) will provide
a usable bandwidth of at least 10Hz –
100kHz (+/-1db) or better.
