Recommended Amplifier Power
For satisfactory performance, we recom-
mend an amplifier with a power rating of
ten to one hundred watts for the HD5;
and ten to one hundred twenty-five watts
for the HD6, and ten to one hundred fifty
watts for the HD8 and HD8.3. 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 informa-
tion 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-
