User manual RANE MM 12

[. . . ] WARRANTY EXPLANATION Rane offers a limited warranty which covers both parts and labor necessary to repair any defects in the manufacturing of the MM 12. The warranty period for the MM 12 is two (2) years, and is determined from either of these two methods, whichever is longer: l. Starting from the date of retail purchase as noted on either the sales slip from an authorized Rane dealer, or on the warranty registration card sent in to the factory, or: 2. Starting from the date of manufacture which is coded on both the inside and outside of the MM 12 chassis, in case the sales slip or warranty card is not available. If you send in the registration card or retain your sales slip as proof of purchase, you will receive a full two (2) year warranty period from the date of purchase regardless of the date of manufacture. [. . . ] Connect the main snake into the system in one of the two following ways. To keep the total numbers of cables and connectors to a minimum, modify the main snake in the following manner: a. Unsolder the main snake cable from the connectors inside the stage box: be sure to label each of the shielded pairs as to which channel it belongs and which colors are connected to which pins. Remove the snake cable from the stage box entirely; you might want to use the stage box for the short snake described in #l above. Strip about 18" of the outer sleeve insulation from the end of the snake cable. Separate each set of shielded pairs and install about 17" of heat shrink tubing over each pair, so that you have 12 or 16 shielded lines emerging from the snake end. Securely tape the area where the outer sleeve ends and all the heat-shrinked lines converge. Now solder a male three-pin connector to each of the shielded pairs, making sure that the colors match the proper pins and channels are numbered as recorded in Step a. ) above. Now you can plug the end of the main snake directly into the PATCH OUTPUTS of the MM 12. if you do not want to modify the main snake, make up to 12 or 16 cables using shielded two-conductor mike cable and a male three-pin connector on one end and a female three-pin on the other end. Use these to connect the stage box of the main snake to the PATCH OUTPUTS of the MM 12. If you are running more than 12 channels through the main board, bypass the MM 12 with the channels that need not be in the monitor system, such as guitars or bass which have their own instrument amps on stage. Connect the OUTPUTS of the MM 12 to the inputs of the monitor amplifiers--balanced lines are recommended if this run is more than six feet or so. IV-l. The MM 12 has 12 inputs but only 8 monitor mix level controls above each output master level. The reason for this is to simplify monitor mixing by doing some clever sub-mixing on the inputs. Most groups possess at least one individual who plays more than one instrument (albeit never at the same time. . . ), such as a keyboard player, drummer, lead guitarist with 4 axes, etc. For example, the large MASTER LEVEL control of output channel #1 sets the overall volume in #1 monitor speaker. The eight MIX LEVEL controls above it determine the specific mix of vocals and instruments (from the MM 12 inputs) to be heard in monitor speaker #1. Making quick adjustments is very straightforward: if the person listening to monitor #3 wants more of his/her own vocal, which is input channel 5, simply go column #3 and turn up mix level control #5. IV-3. USING `THE PARAMETRIC OUTPUT EQUALIZERS. The primary intention of the parametric output EQ is to minimize feedback problems which inherently plague monitor systems. Although versatile and economical, parametric equalizers can be a little tricky to use properly if you are not familiar with them. The following procedure is a recommended method for quickly reducing feedback problems without adversely affecting monitor sound quality. [. . . ] SPECIFICATIONS 12 INPUTS with the following: -Transformerless electronically balanced/unbalanced female three-pin connector input. -Passive MIC splitter with male three-pin connector output. -Input impedance: 8k ohms in MIC or LINE. -Active gain control: 20 dB to 70 dB in MIC.
