Incorporating a Volume Control
It’s possible to control the volume of the sound at the loudspeaker location. Plan to
wire the system so that each loudspeaker has it’s own volume control. Niles makes
a wide range of indoor and outdoor volume controls. Consult your local Niles
dealer for more information. Volume controls are connected in line with the
speaker, so you must connect the wire from the amplifier to the volume control and
then from the volume control to the loudspeaker (
See Figure 3
).
Recommended Amplifier Power
For the OS 5.3Si loudspeaker, we recommend an amplifier with a power rating of
five (5) to one hundred (100) watts per channel for optimum performance. For the
OS 6.3Si loudspeaker, we recommend an amplifier with a power rating of five
(5) to one hundred twenty five (125) watts per channel for optimum performance.
Ironically, most speakers are not damaged by large amplifiers but by small
amplifiers. If you are playing at high volume, 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 “Operation” for more information about clipping distortion.
