CP64S COMMERCIAL PROCESSOR 3 Page Priority Assign allows you to select one of the Page Inputs as a Priority Page Input. The Priority Pager overrides the non-priority Pager in the Zone(s) it is assigned. The non-priority Pager may still broadcast in any Zone that the Priority Pager is not assigned to or not currently broadcasting in. If a Page Input is used for emergencies, set it as the Priority Pager. Set the switch to P1 if you wish Page 1 to have priority over Page 2 (the default setting). If you wish Page 2 to have priority over Page 1, set the switch to P2. If NO is selected, neither Paging Input has priority and both Pagers may be active at the same time. This allows the Paging Inputs to mix for applications like karaoke or PA. 4 5 The Zone 1 Page and Zone 2 Page switches allow you to sum Page signals with Program signals "Pre" (before) or "Post" (after) the VCA. The VCA is used for Zone Level control and Limiting. Therefore, if you require the Page Level to be controlled independent of the Program Level, set the switch for that Zone to "Post." This is the default setting, and is best for emergency paging. If "Pre" is selected, Paging signals sum with Program signals before the VCA. In this instance both Page and Program signal levels are affected by the front panel ZONE LEVEL control. Note the following: • Zone Level, EQ and Limiter circuits do not affect Page signals summed Post-VCA. • Zone Level, EQ and Limiter circuits do affect Page signals summed Pre-VCA. • Page signals are not available on the Expand Zone output when summed Post-VCA. • Page signals are always available for the Expand Page output. There are two internal controls related to the Program Priority detector: 6 Priority Release Time 2 sec to 20 sec (trim pot) Default: 12 seconds 7 Priority Threshold -∞ to -35 dBu (trim pot) Default: -50 dBu The default settings for the Program Priority detector are chosen for most applications. Detector Threshold settings lower than the default setting of -50 dBu are prone to false triggering unless the source is very quiet. If a source is noisy, you may wish to set the threshold higher to prevent false triggering. The default Release Time is 12 seconds. You may wish to decrease the Release Time if the source is a TV, radio, satellite or other relatively constant signal source. If you have a source like a jukebox, with relatively long search times, you may wish to extend the Release Time. CP64S Connections Do not connect the power cable to the CP64S until all connections are made. 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 (maximum 12 guage). 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. Page Input circuits operate balanced or unbalanced. Expand and Zone Outputs are driven by cross-coupled line drivers and operate balanced or unbalanced. For both Inputs and Outputs, wiring is the same. Balanced operation is recommended, and necessary when wire lengths are greater than 10 feet (3 meters). Balanced wiring is (+) to (+), (-) to (-) and shield to shield. For unbalanced operation, we recommend using two conductor cable with shield. The cable is wired to the CP64S 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 CP64S. 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 CP64S 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 CP64S or is of a type that might create grounding problems, use isolation transformers with unbalanced cable. When operating cross-coupled line drivers unbalanced (i.e., any CP64S Output), it is essential to ground the (-) pin. 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. 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. See the RaneNote "Sound System Interconnection" on page 19 to answer any uncertainties, especially when using unbalanced sources.
