User manual RANE CP 52

[. . . ] OPERATORS MANUAL CP 52 COMMERCIAL PROCESSOR QUICK START If you were the type that cheated on school book reports by just skimming through the reading assignments, then this section is for you!It gives you not quite enough information to really know what you're doing. But, if you follow the recommended set up procedure, you should get at least a "B. " Keep the amplifiers and the CP 52 turned off until all connections are made. PAGE INPUT Connect the PAGING INPUT to the Euroblock on the rear panel. [. . . ] ZONE EXPAND switch assigns PAGE-only, PROGRAM-only or full ZONE (both) as the source for the Expand Output. ZONE EXPAND LEVEL trim adjusts the signal level delivered to the ZONE EXPAND OUTPUT. PRIORITY RELEASE TIME control sets the delay time from last detected signal to release of automatic priority override. The range of control is 5 seconds (ccw) to 20 seconds (cw). PRIORITY OFF/ON switch allows disabling the automatic priority override function when in the OFF position. PRIORITY DETECT THRESHOLD control allows adjusting the threshold from - (signal on) to -35 dBu (typ). 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. When OFF, Paging level and Zone level are independent. 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. The Paging detector is always bandlimited to 100 Hz to 7 kHz. 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. 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. [. . . ] This ensures that the level will never be louder than the maximum level just set. Turn the Zone LEVEL control down to a comfortable listening level. Note that with the Paging LEVEL set to minimum, the following Page will not be heard. Speak very loudly (bark) into the Paging mic. [. . . ]
