NXG Technology NX-VMS1003C - Slide Style Impedance Matching Volume Control - Manual (Page 3)

Mounting (Fig. 4)
Using the screws provided,
install the completed assembly
into a single gang electrical
work box, approximately 18
cubic inches or greater. An
open back electrical box or
plaster ring may be more
convenient to work with.
Note: Avoid mounting the
NX-VMS1003C next to AC
lines or dimmers.
Operational Check
After making all connections, check for proper operation. Switch the system to the ON position. Using either the television or music, slowly
increase the volume on the amplifier/receiver to mid position. Now, slowly raise the volume control slider knob on the NX-VMS1003C, from its
minimum position up towards its maximum position. You should hear sound emanating from the speakers, increasing in volume as yo u raise
the volume control slider knob through its twelve steps. Select the level of sound that is most pleasing to you. If no sound is heard from any
or all speakers, switch the system OFF immediately and check for open or loose connections, wrong polarity or shorts in the wires.
Wiring Instructions (Fig. 3)
The NX-VMS1003C has detachable connector blocks to
which the amplifier and speaker wires should be connected.
When connecting the speaker leads from the amplifier out-
puts to the volume controls blue input connector block,
strip about an 1/8 inch of insulation from the wire and twist
or solder it so that there are no loose strands. Insert the
wires from the amplifiers outputs into the volume control
connector block inputs.
Note: Wires should stay consistant right + from the amplifier
to right + on the input side of the connecting block. Most
speaker wire has some form of identification such as raised
ribs or color coding to help determine positive and negative
connections. Connect the speakers to the black output con-
nector block following the same format as above. When the
wires are connected to blocks, plug them back into the vol-
ume control input and outputs. Do not apply undue pressure
while plugging it into the socket. Make sure the plug is
engaged in the socket properly and is not loose.
Caution: Do not reverse the input and output connections
or serious damage may occur to your amplifier.
