Quick Start
We know you’re excited about your new MM 42. But trust us:
take your earphones out for a moment and read this Quick
Start. It covers the basics to get you tweaking your ear mixes
into submission in no time. e following paragraphs assume
you’re working with a stereo (left/right) mix. For more advanced
applications you’ll have to dig a bit deeper into this manual.
First, the hardware. Connect the console aux/groups
corresponding to the left and right ear mixes to the MM 42’s
LINE INPUT A and LINE INPUT B respectively. Send the
MM 42 a good healthy signal, aiming to keep the loudest
peaks around the -8 dBFS mark (yellow LEDs) on the INPUT
meters. Running the Inputs “into the red” is only cool with oldschool analog gear. If needed, make further adjustments using
the INPUT controls.
Turn the PHONES LEVEL all the way down and plug your
earphones or headphones directly into either the ¼" or 3.5mm
PHONES jack. Slowly turn up the PHONES LEVEL to a
comfortable listening volume. Not hearing anything? Press the
CUE BUS button.
Press the COMPRESS button and use the Previous
and Next cursor keys to navigate to the M-BAND parameter.
Rotate the DATA control clockwise until SET starts flashing.
Don’t panic; instead, press the ENTER key to go to the Crossover Frequency page. Adjust the frequency splits for each range,
pushing and turning the DATA control to make fine adjust-
ments. Press the ENTER or COMPRESS key to return to the
Compressor page. Adjust the THRSH parameter until you see a
MONITOR PROCESSOR
few blinky lights on the GAIN REDUCTION meter. Press the
COMPRESS button again to move on to band 2, and again to
move to 3, merrily making adjustments. No, you’re not hallucinating — the GAIN REDUCTION meter does indeed
switch automatically to show you what’s happening within each
frequency band.
Okay, if you’re comfortable with getting around the various
pages then the dry run is over. If you’re using a wireless transmitter, connect the MM 42’s main OUT 1 and OUT 2 to the
inputs of the transmitter and adjust the transmitter’s input gain
to a nominal level. If you’re using a hardwired beltpack, connect the MM 42’s main Outputs directly to the beltpack inputs,
making sure the beltpack level is turned all the way down. Plug
your earphones into the beltpack and slowly turn its level up to a
comfortable listening volume.
at’s it! You’re ready to rock. Or folk. Or country. Or
polka….whatever your musical style. Tweak each processing
section to taste, making sure you go to the MEMORY page
once satisfied and store your hard work to one of the 16 available
(preset) locations.
ere’s plenty more you can do with the MM 42. e rest of
this manual covers important topics like using the SUB Output
to augment an earphone mix with onstage subwoofers or “shakers”, handling two independent mono mixes with one MM 42,
linking and unlinking parameters, connecting multiple MM 42s
together via the Cue Bus, and the wonderful world of MIDI, just
to name a few. So don’t stop here — keep reading! You still have
3 hours until show time.

1 LINE INPUTS A through D: Accept balanced or unbalanced, ¼" phone or XLR-style line-level inputs.
2 DIRECT OUTS A through D: are active balanced pass-throughs of corresponding Line Inputs. Use the DIRECT OUTS to
daisy-chain common mixes to multiple MM 42s.
3 Main OUTPUTS: Balanced, line-level, XLR connections for OUT 1 and OUT 2. Wiring convention is pin 2 positive, pin 3
negative (return), pin 1 is shield chassis ground. Refer to the Sound System Interconnection RaneNote (included with this manual)
for correct wiring when connecting to unbalanced destinations.
4 SUB Output: is balanced (tip-ring-sleeve). Connect to a subwoofer, amp/speaker combination or tactile “shakers” to add low-end
thump to ear mixes. Refer to the Sound System Interconnection RaneNote when connecting to an unbalanced destination.
5 CUE OUT 1 and 2: is a balanced (tip-ring-sleeve), line-level Cue Bus Output. Connect to a spare transmitter or console inputs to
monitor the Cue Bus signal. Signal is identical to the front panel PHONES jacks. e Cue Out level is not affected by the Phones
Level control.
6 CUE BUS jacks: are RJ12 (telephone-style) for interconnecting multiple MM 42s for cueing (soloing) purposes.
7 MIDI OUT/THRU jack: Incoming MIDI data is automatically merged with outgoing MIDI data and passed to the OUT/
THRU if MIDI Merge mode is set to ON (see page Manual-15).
8 MIDI IN jack: Connect this input to the output of another MIDI device (sequencer, controller, MIDI-equipped PC, another
MM 42, etc.) to accommodate data transfers, firmware updates, and external control.
9 Power connector: Uses the standard cord provided. e MM 42 has a universal internal switching power supply that accepts 100
to 240 VAC at 50 to 60 Hz, allowing it to work in most countries.

e rear panel Direct Outputs provide a unity-gain pass-through of each input signal, pre-processing — allowing you to share a common aux/group feed across multiple MM 42s or to feed elsewhere.
For example, create a single or stereo “full band” mix for a group of background singers, and send this feed from the console to
Line Inputs A and B of the MM 42. Augment each person’s mix with an individual feed to Line Input C of each MM 42. Connect
Direct Outs A and B to Inputs A and B of another MM 42. Repeat the process to daisy chain multiple MM 42s together. Use the
front panel Input Levels to set the relative balance between mix elements (full band versus solo instrument) for each performer.
