3.6.2 Two VSP Operating Styles
Although there are endless possibilities in using the VSP creatively, we
will focus on two overall operational styles or setups, in which VSP can be
used within a console setup. In order to use the full potential of the VSP
system, you must be familiar with the two new types of console channels
that are associated with VSP. These are the “VSP Channels” and the “Re-
verb Channels”. These channel types are similar to the other channel types
within the D950/Vista console system (such as Input, Master Output, AUX
Output, Group Output, Control Group Master, etc.).
VSP Channel This is basically a standard Input Channel, however the panner section
uses the VSP panner, rather than the stereo panner or the Multi-Format
panner.
When sitting at the D950 console you can recognize a VSP channel by
selecting PAN to the rotaries. In Page 1, the display at the bottom will read
VSP (as opposed to a Multi-Format panner which will display MPAN).
For Vista users, a small VSP logo is shown in the pan view (in the Viston-
ics touch area).
A VSP channel is identical to an input channel with an Multi-Format pan-
ner, except that it contains the full functionality of the VSP system. As
such it can generate the early reflections and phase-depending signals, as
well as the reverb send signals that the VSP system utilizes. It can also be
used without its VSP functionality.
Reverb Channel This is a special channel type that is only used to generate the late reverb
associated with VSP.
On the D950, you can recognize a reverb channel by selecting INPUT to
the rotary knobs. In Page 1, the display at the bottom will read RVRB.
On the Vista, reverb channels are indicated in yellow and labeled “Re-
verb”.
The reverb channel takes in a mono signal and generates a four-channel
reverb signal that is assigned to the Left, Right, Left Surround, and Right
Surround buses, using the standard bus assign switching of the console.
The two usage styles really describe the manner in which the VSP and
Reverb Channels are used or setup within the console system. They are
operational setups that utilize the VSP functionality in specific ways:
VSP Style In this setup, the source signals (microphone or “tape” tracks) are routed to
VSP channels (input channels with VSP panners). The full capability of
the VSP system is utilized because each sound source has the capability of
being panned to a specific location within the sound field. Based on the
panner setting and the other VSP controls within each channel, individual
early reflections are generated on a channel-by-channel basis (different for
each channel), creating a most realistic acoustic image. Both the direct
sound as well as the early reflections are bused to the outputs by simply
assigning the outputs of the VSP panner as usual. All relationships of di-
rect and reflected sound are handled internally within the VSP panner.
Late reflection (reverberation) “feeds” are also developed within each
channel, and these are sent to one or more reverb channels via special re-
verb buses. Since the reverberation signal only consists of late reflections
that are non-directional, there is no need to develop these signals on a
channel-by-channel basis. Therefore one reverb channel can be used for
any number of VSP channels. For special applications, or to create differ-
