volume Pressing the volume button takes you to the volume setup menu, which in turn
has four submenus, all pertaining to how the volume of the system is managed.
• rotary
• max volume
• startup volume
• mute setup
Each of these topics will be addressed in turn, below.
rotary e rotary knob on the front panel does not directly control the volume.
Instead, it controls circuitry that does so with greater fi delity and precision than
traditional volume potentiometers could ever achieve.
Since the volume control circuitry is under software control, it is possible to
customize its behavior under various conditions. To better understand why this
is so valuable, consider two scenarios:
Person A places a high value on precision in achieving exactly the
volume setting that makes the music most realistic; being able to
easily change volume setting by a fraction of a decibel is critical to his
enjoyment of the system.
Person B just wants to jump easily from low volumes to a reasonable
listening level, and is less concerned with the fi ner points of precision
than with getting what he wants with a quick twist of the knob.
You can see the problem in these scenarios: Person A wants extremely fi ne
gradations on the volume control, which will require many rotations to go from
extremely low setting to normal listening levels; Person B wants to get from one
to the other with a “quick twist” of the knob, requiring coarse gradations in
order to cover so much range in so little space. What happens when Persons A
and B live in the same house? Or if Person C wants to have both, depending on
their mood at the moment? (In fact, most of us are probably like Person C.)
Classé solves this dilemma by altering the response of the volume control, based
on several factors.
Since it is rare to listen at extremely low (barely audible) volumes, the low range
adjustment of the volume control allows for faster response to knob input when
the volume setting values are low. When activated, you will get from extremely
low to middle volume control settings a bit faster than you would otherwise.
is eff ect can be subtle, and may not even be desirable when the speakers used
have extremely high sensitivity (since this results in using the lowest part of the
range more than you would otherwise).
