Rane CP52S CP52S Installation Manual - Page 8

CP52S COMMERCIAL PROCESSOR CP52S Connections All Input and Output connections are made with Euroblock 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 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, and necessary when wire lengths are greater than 10 feet (3 meters). Balanced wiring is logical, (+) to (+), (-) to (-) and shield to shield. For unbalanced operation, we recommend using two conductor cable with shield. The cable is wired to the CP52S 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 CP52S. 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 CP52S and any other unit in the system to have good earth or technical grounds. If a unit is located more than 10 feet (3 meters) away from the CP52S or is of a type that might create grounding problems, use isolation transformers. When connecting any CP52S Output as unbalanced, use (+) and ground - leave (-) floating. Depending on building grounding, an occasional source of system hum is powering sources and amplifiers on different electrical circuits. Try connecting everything on the same circuit. Refer to the included RaneNote, "Sound System Interconnection" on page 17 for more information on proper wiring procedures. ZR1 Remote The CP52S supports a wired remote for Zone Level and Zone Source selection. Wire lengths of up to 1000 feet (300 meters) are possible. A brief list of suitable wire types is provided here in the Wire Types section. The ZR1 remote provides Zone Level and Source Selection, allowing local control from inside the Zone. If only one of the two controls is used, you may wish to remove the unused knob and cover the hole with one of the plugs provided in the kit. If you require one ZR1 remote to control more than one unit, simply wire the ports in parallel. This may be done with the Selector only, Level only or both. Be sure Power to the CP52S is off while all remote connections are made. It is important to ensure that the CP52S Remote Port is not subjected to sustained voltages outside the range of 0 to 5 volts DC or high levels of static. Inputs are protected-however, caution is the better part of... you know. It is a good idea to install the wiring, connect it to the remote assemblies and then make the final connections at the CP52S. Do not short the Vr pin to ground. Although the pin is current limited, excess heat will be generated in the 5 volt supply if a short occurs. Never subject the Vr pin to voltages above 5V. If a ZR1 remote is not used, any simple switch closure to GND will work for the D0 and D1 pins. These pins are TTL compatible (0 to 5 VDC). The logic is inverse Gray Code. Any ground referenced 5 volt DC control may be used as the input to Vc. Do not ground the Vr pin.
