About CISSCA
Commercial Installation Solutions Speaker Calculator (CISSCA) is a software application that
estimates the number of required speakers based on room and target conditions that you specify. It
can also create reports containing the conditions and calculation results, which can be used to suggest
speaker systems to customers.
Certain conditions have been simplified to facilitate and speed up the estimation process. If you want
to specify conditions in more detail, please use Y-S3.

Speakers are automatically arranged in the room based on the room information and speaker density
that were specified in the previous steps. Ceiling speakers are displayed as dots, and the coverage
areas (the area that starts from immediately below the speaker and extends outward horizontally
until the sound pressure decreases by 6 dB) are displayed as circles.
Coverage areas are calculated from the conditions that were entered. They will be slightly different
from the nominal values indicated in catalogs and other related documents.
The spacing between the arranged ceiling speakers is displayed on the right side of the screen.
Room images can be shown/hidden or deleted.
・ Show: Press the SHOW/HIDE button to show or hide the imported

After you configure the application, press the NEXT button to move to the next step.
15
2-5. Adjusting Speaker Output
On this screen, configure the following items.
・ Ceiling speaker density (quantity) and layout type
・ Surface mount speaker quantity, installation spacing, height and angles (tilt and pan)
・ Subwoofer quantity and installation location
Note: ADVANCED mode only.
2-5-1. Ceiling speakers
Adjusting ceiling speaker output
Density (speaker layout density): Adjust the amount of overlap of the coverage areas, which indicates
the boundaries where the sound pressure is 6 dB lower than at the sound receiving point immediately
below the speaker (on the axis). By default, this is set to Edge-to-Edge.
There are five adjustment levels that you can choose from.
High density
Maximum Overlap
Minimum Overlap
Edge-to-Edge
1.4 x Edge-to-Edge
2.0 x Edge-to-Edge
Low density
When you select a certain density, the software starts calculating and redraws the recalculated
coverage areas.
・
Layout type: By default, speakers are arranged in a square pattern. You can also choose a
hexagonal pattern.
・
Speaker spacing: Shows the spacing between speakers.
Note: Speaker spacing is displayed even if only one speaker has been configured.
Consider this to be an indicator of what the spacing would be if there were a second
speaker.
If the number of speakers could exceed 128, an error message will be displayed.
If this happens, select a layout pattern with a lower density.
16
・
Speaker layout patterns
・ Maximum Overlap
In this approach, the -6 dB SPL point of one speaker is aligned with the axis of the adjacent
speakers. This approach requires a larger number of speakers, and is therefore suited for
applications requiring a high sound pressure.
Square
Hexagonal
・ Minimum Overlap
Edge-to-edge speaker layouts can result in gaps in the coverage area. Minimum overlap is
used to eliminate these gaps.
Square
Hexagonal
・ Edge-to-Edge
This approach aligns the -6 dB SPL points of the coverage areas of adjacent speakers. This
is one of the most standard layouts recommended by Yamaha. It can maximize the
performance of Yamaha speakers supported by CISSCA.
Square
Hexagonal
17
・ 1.4 x Edge-to-Edge
In this approach, speakers are spaced 1.4 times further apart than in Edge-to-Edge. As one
of the layouts recommended by Yamaha, this approach reduces the number of required
speakers, resulting in a more economical system than even Edge-to-Edge.
Square
Hexagonal
・ 2.0 x Edge-to-Edge
In this approach, speakers are spaced 2 times further apart than in Edge-to-Edge. This is the
most economical approach, but it is not recommended by Yamaha because it can more easily
result in an uneven sound pressure.
Square
Hexagonal
18
2-5-2. Surface mount speakers
Adjusting surface mount speaker output
Click the Surface Mount Speaker tab to specify settings for arranging surface mount speakers. The
following settings are available.
・ Installation location: Specify the speaker arrangement pattern.
・ None: None.
・ Two: Arranges two speakers in front.
・ Four: Arranges two speakers in front and two speakers in back.
・ Many: Arranges speakers around the room at the specified spacing.
・ Spacing:
・ X: Set the speaker spacing for across the room widthwise.
・ Y: Set the speaker spacing for along the room lengthwise.
This is not available when the layout pattern is set to "Two".
・ Angle:
・ Pan: Set the speaker horizontal angle (pan).
・ Tilt: Set the speaker vertical angle (tilt).
・ Height: Set the speaker installation height.
Note: Please use a period as a decimal point when entering numbers. Commas will be ignored.

After confirming and adjusting the settings, press the View Sound Pressure Calculation Results button
to move to the next step.
21
2-7. Viewing Results
On this screen, you can view a sound pressure distribution map created based upon the specified
conditions.
You can update the map by changing measurement conditions such as the speaker output settings
and the measurement frequency.
View results
The sound pressure (intensity) is represented using different colors on the color bar shown on the
right of the map. You can see that it is highest near the speaker, and decreases as you move away
from it. This is the sound pressure when the wattage selected in the currently selected speaker
output settings (Lo-Z/Hi-Z Tap) is output.
The color bar indicates how the colors are mapped to sound pressure. The target mark shown on
the right side of the bar indicates the target sound pressure set in the application. The arrow
indicates the maximum sound pressure in the current speaker output settings. These are also
shown numerically next to Result (calculated result) and Target (target sound pressure) on the right
side of the screen.
The measurement frequency is usually based on the Overall+A weighted (overall bandwidth with A
characteristic curve correction) setting, but you can also change this. If you select a different
frequency, the Result and Target numeric displays will not be shown.
If SPL on/off (sound pressure map display option) is set to ON, the sound pressure colors and
values that are used in the map are indicated on the right side of the screen. The specified target
sound pressure is also indicated.
The table on the right side of the screen (dBA SPL or dB SPL) indicates the sound pressure
distribution ratios in the room at 6 dB intervals.
・ Speaker List: A list of speakers used in the calculation.
You can temporarily exclude speakers from the sound pressure calculation by clicking the
eye icon shown on the left of each speaker name. This is also reflected in reports.
・
Frequency: The frequency band used for the sound pressure calculation can be selected.
The default setting is overall bandwidth with A curve weighting (Overall A-Weighted). Other
available settings are overall bandwidth (Overall Flat), Low (125-500 Hz), Mid (500 Hz-2
kHz), and High (2 kHz-8 kHz). If you change a parameter, the software recalculates and
redraws the map.
・
Lo-Z/HI-Z Tap: Selects the tap.
The software recalculates the sound pressure distribution based upon the selected values.
22
・
REPORT: The software generates a PDF report that can be printed on an A4 paper based
upon the completed design information. You can open the PDF file in Adobe Reader
(recommended) or a similar application, print it, and provide it as design information.
Note: Overlapping speaker coverage areas creates an acoustic space that allows for great
flexibility. However, at the same time remember that the required number of speakers will
increase. To adjust the number of speakers, go back to the speaker density settings and adjust the
speaker density.
Press the REPORT button to move to the next step.
