Unicom's Wall Mount Impedance Matching Volume
Control is crafted for maximum performance and
durability. Impedance matching ensures crystal clear
sound in any room in your home. Follow the simple
instructions below to start enjoying your quality Unicom
product.
Installation Instructions
1) Remove about 1/4" of insulation from the ends of all
wires to be connected to the Volume Control. Twist the
cable strands to tighten.
Note: The removable speaker/input connectors accept
up to 14 gauge cable.
2) For easier installation, remove the blue connectors
from the Volume Control.
3) Loosen the set screws on the connectors.
4) Connect the leads from the amplifier or receiver to the
INPUT connections; LEFT L (+) and (-) and RIGHT R (+)
and (-). Insert the wire into the correct opening and
tighten the screws firmly.
5) Connect the speaker wires from the speakers to the
OUTPUT connector on the Volume Control. Make sure
that the positive (+) and negative (-) wires of each
speaker are mated to the correct opening on the
connector. Incorrectly wiring this connection will
result in poor sound quality.
6) Replace the blue connectors.
7) Configure jumpers for the total number of speaker
pairs used in the entire installation.
(see note on page 2)
8) Install the completed assembly into the electrical box
or opening.
Note: Insert carefully to avoid excessive strain on the
set screws. If necessary, pre-dress the wires for easier
mounting.
That's it! Now you've made all of the necessary
connections.
