User manual RANE CP 64

[. . . ] OPERATORS MANUAL CP 64 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 64 turned off until all connections are made. INTERNAL SETTINGS: Access to the following internal controls requires removal of the top cover. [. . . ] Program PRIORITY ASSIGN switch to Zone 1 (jukebox in lounge only. ) Both Zone 1 & 2 Expand source switches to ZONE for Page and Program in the restroom and patio. Front Panel Settings: Rear Panel Settings: Use of an isolation transformer is highly recommended with Program audio inputs driven from long cable lines. This is also true for audio sources fed from satellite systems like DSS, DMX, Primestar, AEI, TV Cable, etc. Cable systems are generally earth grounded down the street from the installation. If NO is selected, neither Page Input has priority and both Pagers may be active at the same time. This allows the Page Inputs to mix for applications like karaoke or PA. If a Page Input is used for emergency paging, set it as the Priority Pager. The Z1 Page and Z2 Page switches allow you to sum Page signals with Program signals "Pre" (before) or "Post" (after) the VCA. 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 desired setting 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 ZONE Manual-8 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: · Priority Release Time 2 sec to 20 sec (trim pot) Default: 12 seconds · 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. You may wish to decrease the Release Time if the source is a TV, radio, tape machine or any 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. There is one internal control related to Zone 1: · Zone 1 Mode Mono/Stereo Default: Stereo If you use single conductor cable with shield, connect the shield/gnd wire to both the (­) and shield pins at the CP 64. 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 64 and any other unit in the system to have good earth or technical grounds.
