User manual RANE MLM 82

[. . . ] Now slowly raise the OUTPUT LEVELS as desired. Never connect anything except an approved Rane power supply to the red thing that looks like a telephone jack on the rear of the MLM 82. This is an AC input and requires special attention if you do not have a power supply exactly like the one that was originally packed with your unit. See the full explanation of the power supply requirements on page Manual-3. MLM 82 CONNECTION When connecting the MLM 82 to other components in your system for the first time, leave the power supply for last. [. . . ] 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, ). Rane adheres to the international and U. S. 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. Pin connections are the same as above in . 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. Call the Rane factory for replacement or substitution. A #6-32 screw is provided for chassis grounding purposes. [. . . ] If the MLM 82 is used with mono Inputs, the two OUTPUT controls may be used for 2 different zones. To have one of the sources go to one zone and not the other, insert a signal in one channel, and a dummy plug in the opposite channel. Do not activate the MONO switch in this configuration. If an installation requires independent left-right control for an Input, use the dummy plugs as described in the preceding paragraph, with one in the left channel of one Input, and the other in the right channel of the next Input.
