analog modeling. You can for instance specify a boost of 3

atasamplerateof44.1kHz.Whatthismeansisthatthe
part of the 3 dB boost falling inside the current pass-band
(0to22.5kHz)willbeapplied.Therefore,withtheabove
example,changingthebandwidthofthe28kHzboostwill
result in a noticeable difference.
Note that MS Configuration provides individual equalization
of the M and the S part of the signal, so you can more
surgically access elements of a complex mix. Because
equalization is performed at 48 bit resolution, MD4 has the
headroom to boost even full scale signals, regardless if
processing is done in the L/R or M/S domain.
