Nº40 Media Console Front Panel Operation
this, turn the surround mode knob. For more information on sound
profiles and their use, please refer to “Advanced Features” on
page 7-1.
Alpha-Numeric
Display
The central window of the Nº40 audio processor contains two rows
of twelve alpha-numeric characters. This text-based display
provides you with information on the selected input, the type of
signal being received and/or the current surround mode, and the
current system volume.
Volume Knob
Normally, you turn this knob to adjust the volume of the main
zone (your multichannel theater). The available range is 80 dB,
with 0.1 dB resolution over the top 60 dB, and 1 dB resolution for
the bottom 20 dB.
This control is speed-sensitive. When you turn the volume knob
quickly, it results in a larger volume change than when you turn
the knob the same amount, but more slowly. You can think of it as
being like variable-ratio, power-assisted steering in a luxury auto-
mobile. It delivers both rapid large-scale changes and fine
resolution, on an as-needed basis.
In addition, the volume knob can be used in conjunction with the
balance button to alter the relative volumes and/or delays of the
various speakers in the system.
Sound Profile Button
The concept of a sound profile is central to making the most of
your investment in the Mark Levinson Nº40. In fact, much of the
section “Advanced Features” on page 7-1 deals with the subject;
please refer to that for more detail.
Suffice to say here that pressing the sound profile button cycles you
through the list of defined sound profiles, which are like little
“snapshots” of the system in different configurations. By choosing
a particular sound profile, the system can reconfigure itself on the
fly to better suit the needs of a particular piece of music or film.
Alternatively, you can think of a sound profile as being like a
“macro” of the many changes you might make to the system
manually to optimize it for a particular use. Rather than having to
do so manually every time, define it once, give it a name, and call it
up as needed.
When a profile is selected manually using either the front panel
sound profile button or the profile button on the remote control,
the Nº40 will remain in that profile until either a different profile or
a different input is selected. (Changes in the nature of the incoming
signal that might otherwise have triggered a change in profile are
ignored, in favor of the explicit user selection.)
