Recommended Amplifier Power
For satisfactory performance, we recom-
mend an amplifier with a power rating of
five to fifty watts for the BG-525.
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 quick-
ly. When an amplifier runs out of power it
creates damaging “clipping” distortion. A
large amplifier will play at the same vol-
ume without distorting. See the section on
operating the speakers for more informa-
tion about clipping distortion.
Incorporating a Local Volume Control
In a multi-room system there is one indis-
pensible control 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
