VSS-4
Reverb Diffuse
Range: -25 to 25
This parameter gives you more or less diffusion
than the algorithm designer intended for the
given Decay time. For optimum performance
the diffusion is automatically adjusted behind
the scenes whenever you change Decay times.
This parameter gives you the added control to
vary the diffusion around this automatic setting.
Master Early
Decrease - Restriction in Order
Range: 0 to 100%
Reflection patterns are rendered to a high
order. 1st order reflections have hit one surface
before arriving at the listener, 2nd order
reflections two surfaces etc. High order
reflections are often more diffuse than low order
ones. In Reverb 4000 this effect is emulated by
assigning individual diffusion characteristics to
each reflection.
During perceptual experiments, we have found
that reducing particular orders of reflections can
be useful for optimizing the room response to a
given microphone placement. The 0% setting
will enable the full response while 100% is full
reduction.
Lo Color
Range: -50 to 50
Lo Color adjustment of the Early Reflections
Hi Color
Range: -50 to 50
Hi Color adjustment of the Early Reflections
Early Start
Range: 0 to 100%
Adjusting the Start time is an efficient way of
getting rid of the first reflections that normally
color the source the most. By adjusting the
Start time, the first reflections are discarded but
the timing of the later reflections remain
unchanged. Therefore this adjustment is
typically more acoustically precise and useful
than a normal Predelay control.
The parameter range limit will be less
than 100% if the Early Stop parameter is
set to anything other than 0%.
Early Stop
Range: 0 to 100%
The Early Stop parameter can reduce the later
reflections in the Early Reflections pattern.
When using large location types this can be a
useful parameter to smooth the overall
perception of the room.
The parameter range limit will be less
than 100% if the Early Start parameter is
set to anything other than 0%.
Levels
Reverb Level
Range: Off to 0dB
Adjusts the level of the Diffuse Field reflections.
Early Level
Range: Off to 0dB
Adjusts the level of the Early Reflections from
the two sources.
Dry Level
Range: Off to 0dB
Attenuates the Dry signal level on the Output
side thus leaving the Reverb and Early Level
unaffected. Off equals a “kill-dry” setting.

Location Type
Select between different Locations. Both the
Early Reflection- and Diffuse Field-types are
changed when switching Location to give the
optimal starting point for further adjustments.
