INSTALLATION
The total mounting depth from the wallplate/faceplate to the back of the A-1163P is 3.2".
You must use a minimum of a standard light switch plaster ring (P-Ring) or a standard
20 cu. in. (or larger) electrical box. Suitable P-Rings and electrical boxes are available
from your local electrical supply company. Using the P-Ring during new construction is
best because it gives you unobstructed access to the full depth of the wall (some
building codes require that wall devices be enclosed in electrical boxes; check your
local building code).
Do not install the A-1163P into electrical boxes with 110V devices. Speaker wires can
act as an “antenna” for electrical noise.
Locating speaker wires too close to a light switch or dimmer switch may cause a
“humming” or “buzzing” sound to be heard through the speakers. If you must locate the
Volume Control near electrical devices, install it in a separate metal electrical box,
ground the box to the electrical system ground, and route the speaker wires several feet
away from the electrical wiring.
Install the completed A-1163P assembly in the electrical box. Insert carefully to avoid
excessive strain on wire connections. Taking the time to feed excess wire out the back
of the electrical box will help you with the final mounting.
OPERATION
1. Make sure your audio receiver is OFF and set its volume all the way down.
2. Set the A-1163P volume to maximum (fully clockwise).
3. Make certain the receiver volume is all the way down. Then turn on the receiver and
select a music source, such as tuner or CD player.
4. Slowly turn up the receiver volume and set it to a comfortable (not maximum) listening
level. Be careful not to overdrive your receiver. If the sound becomes muddy or
distorted, you have reached the limit of your receiver’s volume capability and should
quickly reduce the volume to avoid damaging your speakers.
NOTE: 12 o’clock (50%) on most receivers is full volume. A receiver that is being
driven beyond its potential will produce DC voltage (clipping) which will not pass
through a transformer, resulting in improper signal transfer and possible amplifier
shutdown or damage.
5. Use the A-1163P to adjust the speaker volume to the desired listening level.
6. You can turn off the speakers in each room by turning the knob on the A-1163P fully
counter-clockwise.
