User manual RANE MLM 42

[. . . ] If you are using condenser mics, flip the PHANTOM POWER switches to the ON position. Phantom Power only affects the XLR Inputs, not the ¼" TRS Inputs. If an Input Overload indicator lights, this is your clue to turn down its GAIN trim on the rear of the unit. The Output Overload indicator shows the sum of the 4 Input channels, but is located before the OUTPUT LEVEL control. [. . . ] An Output Overload condition is corrected by turning down one or more of the Input LEVELs. 6 OUTPUT LEVEL control determines the level going to all four Outputs. When the yellow LED is lit, the MLM 42 is ready to go. Manual- REAR PANEL DESCRIPTION OUTPUT A EFFECTS RETURN SEND MLM 42 POWER MADE IN U. S. A.

A mono ¼" TS plug may be inserted into the LINE input if necessary, but better results come from a balanced TRS plug. See the RaneNote, "Sound System Interconnection" included with this manual. 2 PHANTOM POWER switch provides 15 volts to condenser microphones plugged in the MIC Input. 3 GAIN trim control sets the inital gain of the Input so the front panel LEVEL control has the most latitude without distortion. When the XLR MIC Input is used, the range of the GAIN is 12 to 50 dB and Phantom Power may be selected. When the TRS LINE Input is used, the range of the GAIN is 0 to 12 dB and Phantom Power is disabled. The unit 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. Never use a power supply with your unit other than the one supplied or a replacement approved by Rane Corporation. Using any other type of supply may damage the unit and void the warranty. 5 ¼" TRS and XLR Balanced OUTPUT jacks are provided for convenience. 6 OUTPUT LINE / MIC switch changes both balanced XLR and ¼" TRS Outputs to either LINE-level or MIC-level. Many DJ mixers have microphone engage and talk-over functions associated with the microphone inputs. By connecting the MLM 42 directly to one of these microphone inputs, you are able to take advantage of these features. 7 A & B Unbalanced RCA Outputs provide connection to line-level inputs. 8 EFFECTS SEND & RETURN loop connects external effects processors or expands to other mixers. [. . . ] The relative mix level of mixer one versus mixer two is determined by the DRY/WET pan control of the second mixer. Other applications for the EFFECTS loop may use only the SEND Output or only the RETURN Input. For example, a drum machine, keyboard or other mono source may be connected to the RETURN Input. The relative mix of the 4 Inputs versus the source present at the RETURN Input is determined by the DRY/WET pan control. [. . . ]
