User manual RANE MLM 82

[. . . ] This gives you a chance to make mistakes and correct them without damage to your fragile speakers, ears and nerves. For best noise rejection use two-conductor-plus-shielded wire, even for unbalanced operation. See the Sound System Interconnection RaneNote included with this manual for all cable adaptations. Rane follows the AES recommended practice of pin 2 postive, pin 3 negative, and pin 1 to shield. [. . . ] To avoid this, the associated OUTPUT LEVEL control may be decreased, or the problem-causing individual Input may be decreased. LEFT and RIGHT OUTPUT LEVEL controls are either Left and Right Output Level controls, or zone 1 and zone 2 Level controls from mono sources. MONO switch mixes the Left and Right channels together with the ratio set by the two OUTPUT LEVEL controls. When active, the associated LED lights, and the Left and Right Output connectors have exactly the same level. POWER LED is lit whenever adequate power is applied to the unit. Manual-2 REAR PANEL DESCRIPTION MIC/LINE INPUT jacks 1-4. These XLRs connect either balanced Microphone or Line signals, depending on the recessed front panel LINE switch setting (see Front Panel, ). standard for balanced pin configurations: Pin 1 is chassis ground (neutral), pin 2 is positive, and pin 3 is negative. PHANTOM POWER switch applies 15 volt phantom power to Inputs 1-4 that are mic-selected (front panel LINE LED off). These XLR inputs split the Input signal to both Left and Right Outputs equally. Choose between this XLR or the ¼" jacks (see below), they do not sum. These pairs of balanced Tip-Ring-Sleeve jacks accommodate stereo line level signals using Left and Right connections. If the source signal is mono, use the LEFT/MONO jack and the internal switching auto-splits to both Outputs equally. These are TRS (tip-ring-sleeve) ¼" jacks accommodating either balanced or unbalanced signals. In most cases an unbalanced signal may utilize a mono ¼" plug (tip-sleeve). For balanced signals use microphone cable (two conductor with shield) with TRS ¼" plugs. See the Sound System Interconnection RaneNote included with this manual for proper connector wiring. These XLRs connect the main Outputs to a power amplifier, signal processor, recorder, or sound system, with the OUTPUT LEVEL switch (see below) set for the correct level. OUTPUT LEVEL switches attenuate the available line level down to a level compatible with microphone preamp inputs. Put these in the out position when LINE level Outputs are desired, and depress them in for MIC level Outputs. The MLM 82 is supplied from the factory with an RS 1 remote power supply suitable for connection to this input jack. The power requirements call for an 18 volt AC center-tapped transformer only. See the note below for details. CHASSIS GROUNDING The MLM 82 is supplied with an external power supply (the RS 1). [. . . ] If the summer approaches overload and the OL indicators illuminate, just turn down the OUTPUT LEVELS until the overload stops--the mix ratios of all the inputs will not change. STEREO LINE LEVEL INPUTS 5-8 The INPUT LEVEL controls adjust both Left and Right Inputs equally. Use the OUTPUT LEVEL controls together for overall output adjustment, or separately to control balance. If the MLM 82 is used with mono Inputs, the two OUTPUT controls may be used for 2 different zones. [. . . ]
