Quick Start

We know you’re excited about the purchase of 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 old-school 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 ⅛"
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 adjustments. Press the EN-

TER or COMPRESS key to return to the Compressor page. Adjust the THRSH parameter until you see a few blinky lights on the
GAIN R EDUCTION meter. Press the COMPR ESS 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.
