The CB18 provides a convenient way to parallel many wires onto a common 2,3 or 4 conductor bus. You
can easily connect many home run leads from multiple IR receivers to the input terminals of a Xantech
connecting block, or from Xantech 760-00 Match Maker™ room volume controls to the output terminals of
a main amplifier.

tors on a 4-conductor bus.
• One-in eight-out or eight-in one-
out capability.
• Adhesive backed labels are in-
cluded for attachment to the plug-
in terminals so that IR or speaker
lead connections can be easily
identified.
• High current design allows ampli-
fiers rated as high as 500 watts to
be used with the CB18.
• Screwterminalshandlewiresizes
from 24 to 12 gauge.
• Dimensions: 11 1/4" x 1-1/4" x 1-
1/4".
INSTALLATION
When connecting an IR receiver/
keypad system, begin by placing
the "VGGS" labels on each of the
terminal plugs as shown in Fig. 2 .
"V" stands for +12 Volts, "G" for
Gnd and "S" for Signal (IR OUT).
This will aid you in keeping track of
your connections.
Fig. 2 illustrates how the CB18 may
be used to connect 8 home runs
from IR receivers and keypads to
theinput terminals of a 789-44 Con-
necting Block in a 9-room system.


2CB18
When connecting speaker wiring, begin by placing the "L+L-R-R+" labels on each of the terminal plugs as
shown in Fig. 3. "L+" stands for Left channel positive, "L-" stands for Left channel negative, "R-" stands
for Right channel negative and "R+" stands for Right channel positive.
Fig. 3 illustrates how the CB18 may be used to connect 8 stereo pairs of home run speaker wires between
the output of a main amplifier or receiver and the inputs of 8 Xantech 760-00 Match Maker volume controls.

INSTALLATION NOTES
• If you have more than 8 stereo pairs of speaker leads or IR signal connections, you may "double-up" on
each terminal plug as needed.
• You may also parallel two CB18's "end-to-end" to gain more connections.
• When paralleling speaker pairs, be sure to follow the instructions that come with the 760-00 Match Maker
volume controls.
• When paralleling IR receivers, a maximum of 12 is recommended. More than this may result in unreliable
operation due to the buildup of IR noise.
• The Smart Pad™keypads may be paralleled in larger numbers. They are not subject to IR noise limitation.
• The CB18 may be mounted to a flat surface using the 2 keyholes in the bottom tray & the screws provided.
Or you can use the two pieces of double-sided adhesive tape, also included.
Note:
Stereo receivers usually have two sets of speaker terminals,
"A" and "B". Be sure to take all speakers connected to both "A"
and "B" into consideration when paralleling speakers, so that
the amplifier does not see an impedance lower than that
specified by the manufacturer.
