User manual RANE CP 52

[. . . ] This Output uses a cross-coupled line driver and may be used balanced or unbalanced. ZONE OUTPUT The ZONE OUTPUT uses a cross-coupled line driver and may be used balanced or unbalanced. ZR 1 REMOTE You may use one ZR 1 Remote (sold separately) with the CP 52. If a ZR 1 remote is not used, any simple switch closure to GND will work for the D0 and D1 pins. [. . . ] When signal is detected at this Input, it is automatically selected as the Program Input source regardless of the front panel PROGRAM SELECT setting. PAGE LEVEL TRACKS ZONE LEVEL switch, when ON, forces the Paging level to track the Zone level. HIGH/LOW CUT FILTER switch, when IN, limits the bandwidth of the Paging Input from 100 Hz to 7 kHz, improving intelligibility in some installations. PHANTOM POWER switch, when ON, enables +15 volt Phantom Power to the PAGING INPUT Euroblock. If the front panel LINE switch is selected, Phantom Power is defeated. PAGING INPUT Euroblock connector may be wired balanced or unbalanced. Manual-3 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 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. 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. Balanced wiring is straight forward, (+) to (+), (­) to (­) and shield to shield. For unbalanced operation, we recommend using two conductor cable with shield. 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 transformers. 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. [. . . ] With an active Program source playing, speak into the Page mic and adjust the DUCKER DEPTH to the desired level of Program during a Page. If an automatic Program Priority override is not required, set this switch to OFF. The front panel PROGRAM SELECT switch will select the "P" Program Input just like any other non-priority Input. If using a ZR 1 Remote control, press the RMT switch in and verify that the remote functions correctly (see page Manual5). [. . . ]
