CP 52 CONNECTION
Be sure the power to the CP 52 is OFF until all
connections are made.
EUROBLOCK CONNECTIONS
All Input and Output connections are made with Euro-
block connectors except for the RCA Program Inputs. When
wiring to Euroblocks, a minimum wire gauge of 22 is
preferred for reliability. If the ground or shield wire is left
shorter, it acts as a strain relief for the other wires. Cable with
a flexible jacket is easier to use and less likely to damage the
connections. Avoid stripping excess insulation. Inspect wires
for nicks that may lead to wire breakage. Fully insert each
wire in the appropriate socket and tighten the screw.
The Page Input circuit is a true instrumentation amplifier
and operates balanced or unbalanced. Expand and Zone
Outputs are driven by high quality cross-coupled line drivers
and operate balanced or unbalanced. Wiring is usually the
same for both Inputs and Outputs. Balanced operation is
recommended. Balanced wiring is straight forward, (+) to (+),
(–) to (–) and shield to shield.
For unbalanced operation, we recommend using
two
conductor cable with shield
. The cable is wired to the CP 52
the same as for balanced operation. At the
other
end of the
cable, connect the (+) wire to signal “hot,” and both the (–)
and
shield wires to ground
(
important
).
If you use
single conductor cable with shield
, connect the
shield/gnd wire to both the (–) and shield pins at the CP 52.
At the
other
end of the cable connect the (+) wire to the signal
“hot” and the shield/gnd wire to ground. When unbalanced
wiring is used, it is very important for the CP 52 and any
other unit in the system to have good earth or technical
grounds. If a unit is located far from the CP 52 or is of a type
that might create grounding problems, use isolation trans-
formers.
When operating cross-coupled line drivers unbalanced
(i.e., any CP 52 Output)
, it is
essential
to ground the (–) pin.
Refer to the included RaneNote 110, “
Sound System
Interconnection
” for more information on proper wiring
procedures.
RCA PROGRAM INPUTS
The four stereo Program Inputs connect to RCA jacks.
These Inputs are unbalanced. The same guidelines given
above for unbalanced operation apply to these Inputs.
