MD 5.1
MD 5.1 algorithm – introduction
MD 5.1 is a multi-channel multi-band expander/
compressor algorithm, with limiters and exten-
sive possibilities to assign channels to multiple
Sidechains.
Based on the MD-2 and Finalizer heritage, four-
band dynamics are here available for 5.1 produc-
tions. With the MD 5.1 it is possible to integrate
dynamics processing in a 5.1 environment offer-
ing features, which will not be possible if using
multiple stereo dynamic processors.
Together with the EQ-5.1 and Toolbox-5.1 algo-
rithms, MD 5.1 is an innovative package of mas-
tering tools for multi-channel productions.
The MD 5.1 algorithm contains:
– 5 channels of three band expansion and com-
pression
– Full-range brickwall limiter on all Outputs
– 1 channel of full range expansion, compres-
sion and limiting for the LFE channel
– 3 Sidechains for the five main channels, that
can be assigned in a flexible way
– 1 extra Input channel that can be used for ex-
ternal Side Chain input.
To utilize the algorithm correctly, make sure that
the Inputs and Outputs are connected as fol-
lows:
– Engine channel 1: Left Front, LFr
– Engine channel 2: Right Front, RFr
– Engine channel 3: Center, Cnt
– Engine channel 4: Low Freq Effects, LFE
– Engine channel 5: Left Surround, LSr
– Engine channel 6: Right Surround, RSr
– Engine channel 7: External Sidechain input,
Xt1 (no Output available)
In the following the parameters in MD-5.1 will
be explained. For further information regarding
Mastering and multiband dynamics processing,
please see the “In-Depth Information” chapter in
this manual.
The MD – 5.1 algorithm occupies:

At the Main page you have access to the general
set-up parameters for the Expander and Com-
pressor sections.
Meters are shown for all seven Inputs and six
Outputs at the right of the display.
Band Xover Frequencies
Lo Xover
Range: Off to 16 kHz
Sets the Cross-over frequency between the Lo-
and the Mid- Expander and Compressor bands
for the five main channels (LFr, RFr, Cnt, LSr,
RSr).
The two Cross-over points are not allowed to
cross each other. Therefore the parameter range
can be less than 16 kHz if the Hi Xover parameter
is set below 16 kHz.
