Input settings
Given that all productions are mixed differently, it is impossible to provide general recommen-
dations regarding settings. By default, settings correspond to a passive M/S encoder without
applying any processing, i.e. L/R stereo is encoded as M/S stereo and the rest of the M/S
Master functions have no influence on the sound. This is the best starting point to get to know
the functions and settings of the unit:
MID/BALANCE: 0 (center position)
MID/INSERT and MUTE: OFF
SIDE/FILTER: 0 (center position)
SIDE/all switches: OFF
SIDE/STEREO WIDTH: 1 (around three o‘clock)
OUTPUT: 0 (around three o‘clock)
VU-switch: all OFF
ACTIVE: ON
At this point, when you switch on or off the M/S Master processing there is no real difference
in the sound. And this is where the fun begins: the original L/R signal is now M/S encoded and
can be processed with the integrated as well as with external processors.
Do note that the M/S Master features exclusively high-quality potentiometers (ALPS RK 27 or
„Big Blue“). But even these potentiometers can exhibit minor imprecisions. Therefore scale
values can be subject to minor deviations. For a perfect 1:1 comparison with the aforemen-
tioned values you ought to consider minor tolerances and compensate if needed. The M/S
Master was not conceived to provide a perfect comparison between L/R and M/S encoding.
Its primary goal is individual processing of audio material, therefore, minor deviations in scale
values do not have a considerable impact on the overall performance. If you wish to have
a higher technical precision, you can always use specifically designed measurement equip-
ment (phase correlation meters, etc.). We have taken these factors in consideration during
development in order to keep a reasonable price/performance ratio.
BALANCE
Use the BALANCE control to place the Mid signal in the stereo panorama. With this control,
the Mid signal created from the sum of L and R can be placed anywhere along the stereo
panorama. In practice, hard left and hard right are not commonly used: normal settings are
somewhere /- 1, and up to 3 at the most. Maximal values are meant to serve as a refe-
rence for testing loudspeakers and acoustical conditions in order to hear if both sides sound
uniformly.
The M/S Master provides two measuring instruments to check Mid balance:
1. The VU-meters. If one channel is continuously higher while in L/R display mode, some
adjustment might be needed.
2. A phase correlation meter (or omnimeter). Adjust the BALANCE control in order for the
phase correlation meter to show a perfectly balanced central position..
