User manual RANE MP 24

[. . . ] OPERATORS MANUAL MP 24 DJ MIXER QUICK START Don't!Quick-starting an MP 24 is like trying to quick-start a 747. Trust us, you don't want to make mistakes with this sucker. So just this once--please--we highly recommend you read this entire manual: front-to-back, every single page, every single word. [. . . ] See the CHASSIS GROUNDING note on page Manual-8 for details. This switch separates chassis ground from signal ground. Normally, this switch should be in the LIFT position. In some circumstances, moving it to the opposite position eliminates stubborn hum and buzz problems. If you are tempted to move this switch with your power amplifiers turned on and cranked up, don't. Always turn your system levels down before changing your grounds around and then bring them up slowly. POWER input connector: No, this is not where Commissioner Gordon plugs in his Bat-phone, in fact it is not a telephone jack at all. The MP 24 uses an 18 volt AC center-tapped transformer only. Use only a model RS 1, or other remote AC power supply approved by Rane. Manual-5 SYSTEM CONNECTION Even though the system variations are limitless in most applications where the MP 24 is used, an installer must follow some basic interconnect guidelines. Unfortunately, even though the system and the primary components such as mixers, processors and amplifiers are of commercial grade, most of the source components, i. e. turntables, disc players, tape decks and so on are consumer grade, with consumer interconnect limitations. Therefore, on the input side of the MP 24, RCA connectors will prevail with unbalanced lines thereto attached. It is recommended, for no scientific reason, that the turntable furthest to the left be connected to Phono 1, and proceed from left to right with Phono 2 and then Phono 3, if used. See SERVICE INFORMATION on page Schematic-1 to convert any PHONO level Input into a LINE level Input. When determining which Line Inputs to use for what, the process becomes a bit more difficult. Obviously, if one of the line devices feeding the MP 24 is of the commercial variety sporting balanced outputs, use Line 2 for this due to its unique ability to accept such foreign substances. The rest of the assignments are pretty much a matter of what you want to appear where on the source switches. Some processors, such as delays and reverbs, have only one mono input and two outputs. This is accommodated automatically by using the MONO Output of the MAIN EFFECTS LOOP. The Zone Outputs and the Booth Outputs are the automatic mono/stereo type. If mono is required, simply connect only to the LEFT OUTPUT. Inserting a plug into the RIGHT OUTPUT automatically renders it stereo. [. . . ] If this is the case, mono outputs may be obtained on all of the Outputs (Master, Booth, Zone) by engaging the SYSTEM MONO switch on the rear panel. When engaged, the SYSTEM MONO switch sums the Left and Right buses together. In this situation, if only one of the stereo Inputs on any of the three Phono or six Line sections is driven, the applied signal appears in equal quantities at both Left and Right OUTPUT connectors. USING THE LIGHTING CONTROL OUTPUT The mono LIGHT CONTROL OUTPUT allows use of lighting systems designed to be triggered from an audio source. [. . . ]
