Controls is not recommended as the wire may not fit into the connectors. NOTE - Never
use solid-core, aluminum or Romex® type wire with volume controls. When running
speaker wires inside walls, most states and municipalities in the U.S. specify that you must
use a special type of speaker wire. Usually, the requirement is that the wire has a specific
“CL” fire
rating, such as “CL-2” or “CL-3”. Consult your Russound dealer, building contractor, or
local building and inspection department if unsure about which type of wire is best for
your application. If you need speaker wire, we recommend you order Russound AW
series wire. These speaker cables use multi-strand copper wire and high-temperature PVC
jackets specially designed for snaking through the walls and for long speaker runs.
CAUTION
Do not install the ALTx sc into electrical boxes with 110 Volt devices. Some states or
municipalities allow devices such as the ALTx sc to be installed into the same electrical
box as 110 volt devices, provided a “low-voltage partition” is used between the devices.
Russound does not recommend this. 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.
OPERATION
1. Make sure the amplifier or receiver is OFF and set the volume to minimum.
2. Set the ALTx sc volume to maximum (fully clockwise).
3. Turn on the amplifier or receiver and select a music source, such as tuner or CD player.
4. Slowly turn up the amplifier or receiver volume and set it to a comfortable (not maxi-
mum) listening level. Be careful not to overdrive your amplifier. If the sound becomes
muddy or distorted, you have reached the limit of your amplifier’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. An amplifier that is being
driven beyond its potential will produce D/C voltage (clipping) which will not pass
through a transformer, resulting in improper signal transfer and possible amplifier shut-
down or damage.
5. Adjust the volume of the speakers to the desired listening level using the ALTx sc.
6. You can turn off the speakers in each room by turning the knob on the ALTx sc com-
pletely counter-clockwise.
