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 IMP100DL, from its minimum position up
towards its maximum position. You should hear sound emanating from the
speakers, increasing in volume as you 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. 2)
The IMP100DL has detachable connector blocks to which the amplifier and
speaker wires should be connected. When connecting the speaker leads from
the amplifier outputs to the volume controls red 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 vol-
ume 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
iden-tification such as raised ribs or color coding to help determine
positive and negative connections. Connect the speakers to the black
output connector block following the same format as above. When the wires
are connected to blocks, plug them back into the volume 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.
