Recommended Amplifier Power
For satisfactory performance, we recom-
mend an amplifier with a power rating of
ten to one hundred watts for the PR5; and
ten to one hundred twenty-five watts for
the PR6. Curiously, most speakers are not
damaged by large amplifiers but by small
amplifiers. If your system is playing loudly,
a small amplifier will run out of power
very quickly. When an amplifier runs out
of power it creates damaging “clipping”
distortion. A large amplifier will play at the
same volume without distorting. See the
section on operating the speakers for more
information about clipping distortion.
Incorporating a Local Volume Control
In a multiroom system there is one indis-
pensible device for true convenience—a
local volume control. It allows you to
adjust the volume of the speakers without
leaving the room.
Plan to wire the system so that each pair
of speakers has its own volume control
built into the wall (think of a volume con-
trol as a dimmer switch for sound).
Niles makes a wide range of high perfor-
mance indoor and outdoor volume con-
trols. They are available in Standard or
Decora

style cover plates (just like your
light switches and dimmers). Volume con-
trols are connected in line with the speak-
