SYSTEM OPERATION
9
Every Wall-Mount Volume
Control in the system
must be set to the same
“Impedance Magnification”
factor.
Do not mix other models
of Niles (or any other
manufacturer’s) volume
controls with Niles
VCS-2D-IM Wall-Mount
Volume Controls in this
type of system
configuration.
Normal Operation
Start by presetting the
volume control on your
amplifier at a reasonable
level. The amplifier volume
control is now the Master
Volume for all of your
speakers. Each room Volume
Control enables you to
reduce the volume of that
room without affecting
anyone else.
To control the volume of your
In-Ceiling Speakers, simply
turn the Wall-Mount Volume
Control clockwise to increase
the volume, and counter-
clockwise to decrease the
volume.
When the Volume Control
is all the way down, the
speaker system is complete-
ly off. When the Volume
Control is set all the way up,
the speakers will play at the
amplifier’s preset volume
setting.
Use caution when
listening to your In-Ceiling
Speakers at high volume
levels. Turning up your
amplifier’s volume too far
may cause the amplifier
to run out of power which
can create “clipping”
distortion, which may
potentially damage your
amplifier, volume control,
and speakers.
Typically, an amplifier
reaches its maximum
capabilities when playing
a CD at a 12 o’clock set-
ting. If you increase the
amplifier’s volume control
beyond that point, the
amplifier will begin to
distort. This “clipping”
distortion will quickly
damage the tweeters of
any speaker (regardless
of its power rating —
power ratings refer to
undistorted sound).
If the treble sounds harsh
and unpleasant when you
are standing near your In-
Ceiling Speakers, reduce
the amplifiers volume to a
safe, undistorted level.
