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.

sound receiving point.

・ Application/maximum sound pressure: Consider your application and set the maximum SPL

that is necessary at the sound receiving point. Specific examples are provided, so select a

setting that is closest to your target (e.g. High BGM/79 dB). In actuality, there will be some

margin on the maximum SPL depending on the number of speakers that are laid out (layout

density).

Note: The applications that are available to select are different for AUTO mode and ADVANCED

mode.

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

image.

・ Delete: Deletes the imported image.

After you configure the application, press the NEXT button to move to the next step.

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.

・ 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

・ 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

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.

2-5-3. Subwoofers

Adjusting subwoofer speaker output

Click the Subwoofer tab to specify settings for arranging subwoofers.

The following settings are available.

・ Installation location: Select the installation location from the nine available choices (corners

or near the center of the room).

You can install up to two subwoofers.

・ Height: Set the height of the installation location. Select "Ceiling" or "Floor".

After you configure the output, press the NEXT button to move to the next step.
