MM 42 Personal Monitor Processor Data Sheet-
Features for the Artist
Process a single stereo mix or two independent mono mixes.
Signal processing, main outputs: Shelf/Cut Filters, 3-band
Compressor, 5-band Parametric EQ, 3-band Peak Limiter.
4 line-level Inputs assignable in any combination to either
output processing chain.
Assignable Sub Output with bandpass filter, assignable to any
combination of Inputs including a mono sum.
6 Memory locations for storing custom user presets.
Add low frequency thump and high frequency sparkle to a
mix using the adjustable Low and High Shelf/Cut Filters.
Control the dynamics of a mix with precision using the
3-Band Compressor
. Adjustable crossover frequencies allow
you to easily tame excess low end, while keeping the vocals and
guitars clear and present.
Use the 5-Band Parametric EQ to improve the overall
sound of the mix. Uses range from simple, broad sweetening
effects to precise boosts or cuts to account for a performers hear-
ing loss or a particular earphones response.
Protect the performers hearing and keep output levels under
control using the 3-Band Peak Limiter. The Limiters crossover
frequencies are fully adjustable and independent of the Compres-
sors crossover settings.
Monitor the mix pre- or post-processing using the on-board
headphone amp.
Both 1/4" phone and 1/8" mini jacks are offered
on the front panel. In many cases the headphone amp can re-
place a hardwired beltpack for the less mobile musicians on stage
the drummer or keyboard player, for example.
Save precious Aux outputs on the mixing console by using
the Direct Outputs to daisy chain (pass-through) a common
mix or mixes across multiple MM 42s. Feed a bands stereo mix
through to multiple MM 42s using the Direct Outs, then use
the additional Inputs on each device to add solo instruments to
the overall mix.
Recall memory presets and adjust parameters remotely via
MIDI.
MIDI Sys Ex is also used to backup system settings and
for device firmware updates.
General Description
Ranes MM 42 Monitor Processor fulfills the demanding needs
of performers and engineers striving to optimize personal moni-
tor systems while ensuring a safe, dynamic mix. Connected
in-line between a mixing console and a wired or wireless monitor
system, the MM 42 processes a single stereo mix or two inde-
pendent mono mixes using Shelf/Cut Filters, 3-band Compres-
sor, 5-band Parametric EQ, and 3-band Peak Limiter. An assign-
able Sub (low frequency) output with adjustable bandpass filter
is included for direct connection to powered subwoofers or bass
shakers without requiring an external crossover. The on-board
headphone amp and Cue Bus functionality permit easy setup
and monitoring of multiple mixes.
Process a single stereo mix or two independent mono
mixes
using the MM 42s flexible input to output routing. Any
combination of the MM 42s four line-level inputs is assignable
to any output processing chain. The relative mix of inputs is eas-
ily adjusted using front panel level controls, making more me
mixes a breeze.
Create a separate low-frequency mix for driving onstage
subwoofers or tactile thumpers using the Sub Output with
adjustable bandpass filter. Any input or combination of inputs is
assignable to the Sub Output. External crossover not required!
Connect multiple MM 42s together using the Cue Bus and
avoid the hassle of having to constantly re-patch headphones
when monitoring more than one mix. Any mix can be placed
on the cue bus and monitored (soloed) simply by pressing the
desired mixs CUE BUS button. Connect the dedicated Cue
Outputs
on the rear panel to a spare transmitter or hardwired
beltpack and hear the mix exactly as the performer hears it.
