Thank you for choosing the IMP80D impedance matching volume control. Speco
The IMP80D is a unique adjustable designed impedance matching stereo volume control. The impedance matching 2x, 4x, 8x or 16x
switch positions enable the IMP80D to connect up to 16 pairs of 8 ohm speakers or 8 pairs of 4-ohm speakers to a single 8 ohm stable
amplifier and operate them simultaneously without the fear of amplifier overload, eliminating the need for a speaker selector or other imped-
ance matching device.
(Note: When using a 4-ohm stable amplifier, you can connect up to 32 pairs of 8 ohm speakers or up to 16 pairs of 4 ohm speakers.)
Wiring and Installation
First determine the minimum operating impedance of the
amplifier to be used in your installation. This information should
be in your amplifier owner anual. Using the speaker chart ats m
left choose the proper position for the impedance matching
switch (see Fig. 1) and put the switch in the correct position.

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. No slowly w,
rotate the volume control knob on the IMP80D, from its minimum position
towards its maximum position. ou should hear sound emanating from the Y
speakers, increasing in volume as you rotate the volume control 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 FF immediately O
and check for open or loose connections, wrong polarity, or shorts in the wires.
Wiring Instructions (Fig. 2)
The IMP80D 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
volume control connector block inputs.
Note: Wires should stay consistent 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
the blocks, plug them back into the volume control input and output. 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.

ter ring may be more convenient for all the wiring to fit.
Note: Avoid mounting the IMP80D next to AC lines
or dimmers.
