TOA Speaker Placement Viewer v2.0.1
---------------------------------
---------------------------------

-------------------------
Installation Instructions
-------------------------

The TOA Speaker Viewer software is a self-contained, executable program that 
can be run directly from the CD-ROM. Alternatively, you can also copy the 
following to your computer's hard-drive:

TOA_SPV.exe (main program)
TOA_SPV.ini (initialization file to user preferences)
Speaker_Data (folder of TOA and generic speaker data files)

--------------------
Program Instructions
--------------------


-----------------
Define a new room
-----------------

* Select "File | New Project" from the menu bar or click on the "New" toolbar icon.
* Enter all information in the Room Properties dialogue, and then press OK button
  to use these room properties. These properties can be edited at a later time by
  selecting "Room | Properties" from the menu bar.
      ** Project Name : Enter the name of the project associated with this data.
      ** Date : Enter the project's date.
      ** Units : Select the units used for the project (Metric / Imperial).
      ** Room Dimensions | Zero Position(X) : Enter the position of the left end
         of the room. (Only available in the Advanced Mode.)
      ** Room Dimensions | Zero Position(Y) : Enter the position of the bottom
         end of the room. (Only available in the Advanced Mode.)
      ** Room Dimensions | Length(X) : Enter the room size from left to right.
      ** Room Dimensions | Width(Y) : Enter the room size from top to bottom.
      ** Room Dimensions | Height(Z) : Enter the ceiling height.
      ** Room Dimensions | Grid Pitch(X) : Enter the size from left to right 
         of the ceiling tile. 
      ** Room Dimensions | Grid Pitch(Y) : Enter the size from top to bottom
         of the ceiling tile.
      ** The position and size of the calculation plane are automatically set.
         Uncheck "Same as room dimensions" to set these dimensions separately. 
         Limiting the size of the "Calculation Area" is helpful to save time during 
         your simulation.
      ** Select the direction of the calculation plane (Parallel to XY Plane /
         Parallel to YZ Plane / Parallel to XZ Plane).
      ** Height(Z) from XY Plane / Length(X) from YZ Plane / Length(Y) from XZ Plane :
         Enter the offset length from either basic plane to the calculation plane.
      ** Larger settings for "Pitch of Color Dot" will speed up the calculations.
         However, this results in a rougher simulation.

-----------------------
Import the speaker data
-----------------------

* Select "Speaker | Import" from the menu bar to import speaker data (*.tsa) to use 
  in the simulation. This is displayed on the left hand column under "Speaker Name".

----------------------
Automatic Installation
----------------------
(This function is only available for the ceiling speakers in case the calculation plane
is set parallel to XY plane.)

* Select the speaker on the left hand column under "Speaker Name".
* Select the power tap and impedance under the lower left hand column "Tap".
* Select "Installation | Auto" from the menu bar for the program to automatically 
  place selected speaker in defined room. 
* Enter all information in the dialogue.
      ** Speaker Density
         1)Maximum Overlap
             This should be used when extremely high quality sound is demanded.
         2)Minimum Overlap
             This should be used in the case with many reflective surfaces and high 
             ambient noise.
         3)Edge-to-Edge
             This should be used for a relatively dead room with low ambient noise.
         4)1.4 * Edge-to-Edge and 2 * Edge-to-Edge
             In some cases, these settings may be used to fit within a tight budget.
             The designer should be mindful of the significant variations in level 
             and sound character around the room, that will result with these 
             settings.
      ** Layout Pattern
         1)Rectangle
             This pattern often requires fewer speakers, resulting in a lower system 
             cost, and this choice is usually preferred since it is easier for actual 
             arrangement and even coverage.
         2)Hexagon
             This pattern typically uses more speakers and yields much more even 
             coverage.
* After clicking OK, the recommended number and placement of speakers will be 
  automatically calculated and the results displayed.

-------------------
Manual Installation
-------------------

* Manual placement of speakers can be accomplished two ways. 
      1) Drag and Drop the speaker name displayed on the right hand column under 
         "Speaker Name" onto the color mapping view.
      2) Select "Installation | Manually" from the menu bar. A dialogue box will 
         appear where the location of the speaker can be entered.
* The speaker in the color mapping view can be dragged and dropped outside the room to 
  remove the speaker already installed.
  ("Installation | Remove" or "Installation | Remove All" in the menu bar can be used
   for same operation, or a right click on the speaker.)
* The speaker already installed in the color mapping can be moved by Drag and Drop.
  (Selecting "Installation | Properties" from the menu bar or a right click realize the 
  same function.)

---------------------------------------------------------
Select the Frequency, Bandwidth, and Energy/Interference
---------------------------------------------------------

* Three drop-down boxes above the color mapping allow selection of center frequency, 
  bandwidth, and the method for data averaging. When these are changed, the energy 
  distribution is recalculated. Interference is used in calculation only when
  "Interference" is selected and this is more realistic.

----------------------
Save Project and Print
----------------------

* The report can be saved (Select "File | Save Project As" from the menu bar) and/or 
  printed (Select "File | Print" from the menu bar).

-------------
Advanced Mode
-------------

* More detailed placement of speakers is possible by selecting "Tool | Preferences"
  from the menu bar and then check on "Advanced Mode".

--------------------
Manual Recalculation
--------------------

* Recalculation occurs every time speakers are moved or removed at the default. 
  If you do not prefer this for cases such as large rooms, select "Tool | Preferences" 
  in the menu and then check "Manual Recalculation". There is no calculation until 
  "Tool | Recalculate" in the menu is selected.

------------------
Module Arrangement
------------------

* The module configuration of the speakers having modules can be changed by selecting
  "Speaker | Module Arrangement".

--------------
View Direction
--------------

* The view direction can be changed by selecting "View | Room | Direction".

------------------------
Note : Calculated Result
------------------------

* Calculation uses both magnitude and phase response data and includes phase/
  distance-related interference effects, yielding a realistic model.
* Average SPL in the audience plane is calculated as follows :
      ** Average SPL = Speaker Sensitivity (1W, 1m) X Input Power / Distance
* The peak-to-RMS ratio is generally considered to be 10dB for pink noise and  
  3dB for a sine wave. Therefore, to make the results more realistic
  and avoid amplifier saturation, subtract up to approximately 7dB from 
  the calculated result.
* Power compression (voice coil temperature rising causing the impedance to increase), is 
  left out of the formulas in this software, because the ratio of compression depends on
  the type of transducer, the type of signal source, etc.
  It is generally assumed that up to approximately 6dB of compression can occur. 

----------------------------------
Note : Recommended Amplifier Power
----------------------------------

* Calculation is given as below :
      ** High Impedance : 120% of sum of taps.
      ** Low Impedance : Sum of speaker power handling (continuous pink noise) to 
         sum of speaker power handling (continuous program). The ratio of program by
         pinknoise is 2 or 3 depending on the signal type for the power handling test.
         In general, TOA uses the test noise of the crest factor 2 for "BGM / Paging"
         speakers and the crest factor 3 for "Music / Speech Reinforcement" speakers.
