MLM103 Mic/Line Mixer

MLM103

The Rane MLM103 Mic/Line Mixer features six balanced, studio-grade microphone inputs and two balanced, stereo line-level inputs. The microphone preamplifiers include direct outputs. These can monitor the signal ‘pre’ or ‘post’ the mix Level control via rear panel switches. Each microphone and stereo line input features three-band EQ and mix level controls. Input overload indicators are peak detecting and illuminate 4 dB before clipping. Three balanced outputs are provided. A and B outputs may be used as a stereo pair in a single zone or as two independent mono zones. The AUX output is mono. All connections are via Euroblock connectors.

Inputs 1 through 6 may be individually switched between Mic or Line level via rear panel switches. Inputs operate in Mic mode with a gain range of +12 dB to 60 dB. Each pair of Inputs may operate with or without 12 volt phantom power via rear panel switches. When Inputs are operated in Line mode, the gain range is -4 to 12 dB. When Line mode is selected, phantom power is defeated. Each Input may be assigned to the A, B or AUX Output.
Stereo Line Inputs 7 through 10 accommodate +24 dBu signal levels. The gain range is –∞ to +12 dB. The A/B Assign switch for Inputs 7/8 assigns 7 to Output A and 8 to Output B. The A/B Assign switch for Inputs 9/10 assigns 9 to Output A and 10 to Output B. The Mono switch sends the sum of Inputs 7 and 8 (or 9 and 10) to bus A and bus B. Assigning 7/8 or 9/10 to AUX sends the sum of Input 7 and 8 (or 9 and 10) to the AUX Output.

The A, B and AUX Outputs feature independent level controls and 10 segment meters with peak hold. Each balanced Output provides an additional 6 dB of gain and delivers a minimum signal level of +24 dBu into a 10 kΩ load.

The MLM103 features a built-in high efficiency, universal voltage power supply that can operate in almost any country in the world. A security cover for the EQ and Assign switches is included with the unit.

Application: Small House of Worship

MLM103 for House of Worship

The MLM103 can deliver a stereo mix to the Main Sanctuary, or if a three rooms if they only need a mono mix. The mic direct outputs may be used with other mixers for a sermon-only recording, or stage monitor for the keyboardist.

Application: Meeting Room Combine

MLM103 for Room Combine

The MLM103's Assign buttons can send each mic to A. B, and AUX independently. Whichever room a mic jack is located in, its mic can be heard in any or all rooms. Mics may be wired from a breakout box or a pair of mic jacks on the wall in each room. Stereo sources are switched to mono. The mic direct outputs may be used for additional un-switchable zones.
