VII. VIRTUAL ACOUSTICS SETTINGS
Virtual Acoustics™ provides the spatial ambiance of reverberant rooms of various sizes.
Although most effective in poor (non-reverberant) acoustic environments, it enhances the
sound even in optimal acoustic settings.
There are 21 selectable reverb pallets. One of these, the DEFAULT setting, is not
adjustable. The other 20 pallets are selectable and adjustable. They allow an organist to
modify the sound of the organ to accommodate a room's changing acoustical properties.
For example, a room's reverberation characteristics change as the number of people
present changes. Differences in reverberation time also occur when a room's windows
are opened or closed.
The rocker switch labeled VIRTUAL ACOUSTICS™ in the Console Controller must be
ON to hear the selected reverb. The amount of reverb can be changed on the 20
adjustable selections. The selected reverb level, measured in dB (decibels), is shown in
the Console Controller™ window. The range of control is from Ø dB to -3Ø dB. Minus
3Ø dB is the least amount of reverb; Ø dB is the most reverb available. When you
change the Virtual Acoustics™ setting, you must turn the rocker switch OFF and ON
again for the new setting to take effect.
VIII. INSTALLATION, VOICING, AND CARE OF THE ORGAN
Wherever your Protégé Theatre Organ may be situated, careful installation is a
prerequisite to achieving successful results. Your Allen representative is well qualified to
guide you in planning for this. Allen Organ Company factory assistance with planning
the installation is available and may be sought by your local Allen representative. Once
the organ is installed, be mindful of changes made to the room it is located in. Care must
be taken to insure that when acoustical changes occur, your Allen Organ representative is
notified.
