VSS™ M4
Introduction
Multiple mono reverbs may often be more use-
ful than pre-configured structures for stereo, 5.1,
6.1 etc. The M4 algorithm offers 4 discrete mono
reverbs with 4 in and 4 out in one Engine.
M4 reverbs can be used in multiple mono config-
urations, where the effect has to end up in pre-
dictable places, or combined to cover arbitrary
multichannel configurations like 7, 10 or even 16
main channels with different settings, all within
one Reverb/System 6000 frame.
VSS™ in Mono
All VSS™ reverbs feature de-correlated diffused
field responses. Such structures are costly from
a DSP and memory point of view, but the ben-
efits become obvious if the mix-format is altered
during reproduction, e.g. if listening to stereo
material in mono, 5.1 in matrixed surround or ste-
reo. The balance between wet and dry signal re-
mains the same, so a deliberately wet stereo mix
doesn’t suddenly turn into a dry version heard
through a kitchen radio.
The individual reverbs in the M4 handle correla-
tion in a fully flexible manner: Each of the 4 mono
reverbs can be set to different modes, ensuring
a de-correlated response even if all parameters
are set identically.
The VSS™ M4 algorithm occupies:
– @ Normal Sample Rate: 1/4 DSP Resource
– @ Double Sample Rate: 2/4 DSP Resource
The inputs and outputs of this algorithm are dis-
tributed as follows:

Parameters listed below may have shifted in final
implementation.
Master Decay (Reverb 1 to 4)
Range: 0.1 to 20 s
Individual Decay parameters of the four reverbs.
This parameter is also available on the Reverb 1
to 4 sub pages.
Pre Delay (Reverb 1 to 4)
Range: 0 to 300 ms
Individual Pre Delay parameters of the four re-
verbs.
This parameter is also available on the Reverb 1
to 4 sub pages.
Hi Decay (Reverb 1 to 4)
Range: 20 Hz to 20 kHz
Individual Hi Cut parameters of the four reverbs.
This parameter is also available on the Reverb 1
to 4 sub pages.
Link Mode
Options: Link 1+2 – Link 1+2, 3+4 – Link All
The Link modes are used to link parameters be-
tween the four Reverbs. E.g if “Link 1+2” is se-
lected the Master Decay of both Reverb 1 and
Reverb 2 is controlled with a single handle. The
same applies for the Pre Delay and HI Decay pa-
rameters.
