C45 Preamplifier Features
SELECTABLE INPUT TITLES
The displayed name of each input of the C45 may be changed to match the
available sources. Names are chosen from a selection of 14 different titles.
Additionally, the sensitivity for each input is adjustable to enable a uniform volume level between source components.
VOLUME LEVEL
Master volume control for all channels is achieved through a sophisticated
optical encoder. Utilizing light pulses ensures accuracy and eliminates
effects of mechanical wear.
BASS AND TREBLE CONTROLS
Precision tone shaping 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.

An IR remote control is included. Remote keypads and external sensors
are available.
