Manual-9
(to account for an artist’s hearing difference between right
and left ears, for example) or to process two completely
independent mono mixes.
To Link or Unlink an individual processing section:
1. Select the desired processing section.
2. Navigate to the Selected Output(s) field
3. Rotate the DATA control to select between adjusting
parameters for OUT1+2 (linked) operation, OUT 1 only, or
OUT 2 only.
PEQ ON | EQ GAIN FREQ BW (Q)
OUT 1+2| 1 0dB 100Hz 1/3 (4.3)
When OUT1+2 is selected, Output 2’s parameters are set
to match those of Output 1.
Note that OUT 2’s settings are
not permanently overwritten. Switching back to OUT 2
restores them to their previous values.
Bypassing Processing Sections
A wise man once said “it’s not a feature if you can’t turn it
off.” Each processing section in the MM 42 can be turned off,
allowing for quick before-and-after comparisons, or to bypass
an unused section altogether.
To bypass a processing section:
1. Navigate to the status area of the processing section.
2. Rotate the DATA control counter-clockwise until off
is
displayed.
PEQ off| EQ GAIN FREQ BW (Q)
OUT 1+2| 1 0dB 100Hz 1/3 (4.3)
If parameters are unlinked (OUT 1 or OUT 2, instead of
OUT1+2), only the processing section for the currently
selected output is bypassed.

Signal Processing
Overview
So what does the MM 42 have under the hood you ask?
Plenty! Routing options allow the assignment of any combi-
nation of the four Inputs to any of the three Outputs:
OUT 1, OUT 2 and SUB.
Each of the processing chains for OUT 1 and OUT 2
features (in this order): Shelf/Cut Filters, a 3-band rms
Compressor with fully adjustable crossover frequency points,
5-band fully Parametric EQ, and a 3-band Peak Limiter, also
with fully adjustable crossover frequency points. The SUB
output processing chain is completely independent of the
main outputs and features adjustable Low- and High-Cut
Filters for maximizing onstage thump.
Why is the Output Level located
before
the Limiter?
Placing the Output Level before the Limiter allows you to
turn up a compressed and equalized mix while maintaining
the Limiter’s brick wall protection. Note that there may be
some interaction between the output level and limiter,
depending on how the limiter is set. For example, if the
limiter is set up to catch the occasional peak and you then
turn the output level up by 6 dB, expect to see more limiting
as the entire mix is now 6 dB closer to the threshold.
Linking and Unlinking Parameters within
Processing Sections
Parameters within each processing section can be linked
or unlinked, depending on the application. Adjusting param-
eters in linked mode affects both outputs simultaneously and
is particularly useful when working with Stereo mixes, as it
allows you to change one set of parameters and affect both
sides of the mix identically. Unlinking parameters allows you
to make individual adjustments to each side of a stereo mix,
