Rane MLM103 MLM103 Manual - Page 8

CONNECTION INPUTS The MLM103 has ten balanced Euroblock Inputs. Use only shielded cable, #12 to #24 AWG. For best noise rejection use two-conductor-plus-shielded wire, even for unbalanced operation. Connect the non-inverting (positive) audio lines to the "+" terminals, and the inverting (negative) lines to the "-" terminals. Connect the shields to the "ground" terminals. For those installations where the MLM103's internal shieldto-chassis connection causes interference, connect the shields directly to chassis PEM nuts directly above each pair of Euroblock connectors. Be sure to bite through the paint with the star washer and keep the shields wrapped around the audio conductors as much as possible. For the "theoretical" best ElectroMagnetic Interference (EMI) immunity, connect the shields at both ends of the cables. (For more information on connections, see the RaneNote, "Sound System Interconnection" later in this manual or on Rane's website.) MONO INPUTS 1-6 can accept either mic or line level sources. When connecting line level signals, push the rear panel button in for LINE. For mic signals, be sure the button is in the MIC (out) position. STEREO INPUTS 7/8 and 9/10 accept line level stereo and mono sources. OPERATION MONO MICROPHONE/LINE LEVEL INPUTS 1-6 The rear-panel MIC/LINE INPUT TRIM adjusts the input gain before the front panel LEVEL controls. When an Input's LINE/MIC button is in the "out" position (Mic Level), the gain range is 12 to 60 dB. When an Input's LINE/MIC button is in the "in" position (Line Level), the gain range is -4 to 12 dB. First, input some "loud" source material (like a pop metal or disco CD, give a kid a mic, etc). Then, using a screwdriver, adjust the TRIM for each Input so that the front panel OL LED illuminates only occasionally during extreme peaks. The 3-band Equalizer settings will influence this, so keep on eye on the OL when making EQ adjustments. Push the PHANTOM POWER button (when needed) for each pair of Inputs. If the LINE/MIC button is engaged (Line Level), Phantom Power is automatically defeated for that Input. The PHANTOM POWER button activates 12 volts which is sufficient power for all but the most esoteric condenser mics. If in doubt, check the manufacturer's microphone specs. Assign each Input to the desired Output by pushing any combination of the A, B or AUX ASSIGN buttons. The LEVEL of each Input can now be adjusted as needed without danger of blowing your speakers, or scaring the neighbors, whichever you deem worse. OUTPUTS The MLM103's OUTPUTS (and DIRECT OUTPUTS) are balanced. The same wiring conventions as the Euroblock Inputs apply. STEREO LINE LEVEL INPUTS 7/8 and 9/10 When a stereo source (CD, DVD, Satellite radio, etc.) is connected to Inputs 7/8 (or 9/10), the routing is as follows: When the ASSIGN button is engaged and the MONO button is not engaged, INPUT 7 (or 9) is routed to the A Output, while INPUT 8 (or 10) is routed to the B Output. When both the ASSIGN and MONO buttons are engaged, a mono mix of INPUTs 7/8 (or 9/10) will be routed to both the A and B Outputs. The AUX ASSIGN button is always a mono mix of the stereo channel. OUTPUT LEVELS After all of the Mic/Line and Stereo Input Levels have been adjusted and routed, adjust the OUTPUT faders so the Meters peak average around 0 to +2. SECURITY COVER The MLM103 comes with an installed security cover for the EQ and ASSIGN switches only, leaving the LEVEL controls and metering exposed for regular operation. This feature is valuable when you want to protect those painstaking settings from casual operators. The cover is removed and replaced by two screws. If the security cover will not be used, remove the chrome standoffs from the front panel and replace with the black screws in these same locations. ©Rane Corporation 10802 47th Ave. W., Mukilteo WA 98275-5000 TEL 425-355-6000 FAX 425-347-7757 WEB rane.com Manual-4 111584
