SELECTABLE INPUT TITLES
The displayed name of each
input of the C45 may be changed

selection of 14 different titles.
Additionally, the sensitivity
for each input is adjustable to
enable a uniform volume level
between source components.

channels is achieved through a
sophisticated optical encoder.
Utilizing light pulses ensures
accuracy and eliminates
effects of mechanical wear.

circuitry is provided
to enable adjustment
of the acoustic balance of
the sound. A bypass
switch completely removes
the tone controls from the
audio signal path.
