File compatibility with previous versions Version 2.1: No compatibility Version 3.0: Reading and sound pressure calculations for files created in Version 3.0 available. Files created with Version 3.1 are not compatible with Version 3.0. Sound pressure cannot be calculated for files that use added speaker data. The impedance setting is unified with the setting of the ceiling speaker. File compatibility with future versions It is not compatible with newer versions that will ship in the future.

1. Starting CISSCA To start the program, double-click the CISSCA icon on the desktop, or click "Programs" > "YAMAHA" > "CISSCA_Ver3" from the Start menu. When the program starts, the initial screen (HOME screen) appears. HOME screen CISSCA is designed in a wizard format. From the HOME screen, you can simply enter conditions to specify the number of speakers and other design parameters. A design for a single room is referred to as a "project", and can be managed like a file. 1-1.
1-2. Creating a Project Select "New" on the initial screen (HOME screen) to open the Project Settings screen. Project Settings screen Enter the name, memo, and the configuration method for the new project. Enter the conditions (as shown below) and then run the simulation. [AUTO configuration method] • 2.1: Enter room conditions • 2.2: Configure speaker density • 2.4: Configure the application • 2.6: View settings • 2.7: View results • 2.8: Generate report [ADVANCED configuration method] • 2.
1-3. Editing a Project Select "OPEN" on the initial screen (HOME screen) to open the Select Previous Project File screen. 1-4. Common Features After a project is created, you can save it at any time (SAVE). Other common features are as follows: • NEW: Creates a new project. • OPEN: Opens an existing project. • SAVE: Saves the project. • SAVE AS: Saves the current project with another name. • Export CSV: Saves the project content to a CSV (comma-separated text) file. • OPTIONS: Set various CISSCA options.
2. Data Entry 2-1. Entering Room Conditions Click "OK" on the Project Settings screen to start a new project. If you click "OPEN" on the HOME screen and select an existing project, the screen that was displayed when the project was saved appears. Room information settings On this screen, enter the environmental information of the target room ・ Project name Enter a name for managing this design information. (e.g.
You can also import blueprints or another image to more easily visualize the room. Imported images may be moved or resized as follows. Image operations ・ Move: Press the Move button to use the mouse to move an imported image. The button will appear as shown in the figure to the left when the image can be moved. ・ Scale: The image can be resized by entering a scale value or by dragging the scale slider. A scale value of 1 represents the original size of the image. It can be set to a value of 0.
2-2. Configuring Speaker Density On this screen, configure the speaker density. Note: AUTO mode only (the speaker type is set to ceiling speaker and cannot be changed). Speaker density settings ・ Density: Configure the number of speakers (layout density). * Explanations for each setting are shown in the Settings screen. After you configure the speaker density, press the NEXT button to move to the next step.
2-3. Selecting the Speaker On this screen, configure the impedance and the speaker to use. Note: ADVANCED mode only. Impedance and speaker settings ・ Impedance: Select the speaker connection method (high-impedance connection or lowimpedance connection). ・ Speaker: Select the speaker to use. When you select a speaker, its photo and usage information are displayed on the right side of the screen. Some speakers may not be available to select, depending on the connection method.
2-4. Configuring the Application On this screen, set the required sound pressure target (target SPL). Application settings (ADVANCED mode is shown here) ・ Application: Consider your application and set the maximum SPL that is necessary at the 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).
Application examples: Name Quiet BGM Low BGM Mid BGM High BGM Low FGM/Speech FGM/Speech High FGM Low Ent. Music Low Ent. Music Mid Ent. Music Mid Ent. Music High Ent. Music High Ent.
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.
・ 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.
・ 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.
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.
2-5-3. Subwoofers Adjusting subwoofer 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 nine subwoofers. ・ Height: Set the height of the installation location. Select "Ceiling" or "Floor". Some subwoofers may not be selected for "Floor" installation.
2-6. Viewing Settings This screen shows information on the speakers that were automatically arranged based upon the room information, speaker density, and application that were specified in the previous steps. View settings Speakers that were automatically arranged can be moved and deleted. ・ Speakers: Selects the speaker to manipulate. ・ Move or delete: Selects how to manipulate the speaker. ・ [Move] Use the mouse to move the applicable speaker (dot).
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.
・ 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.
2-8. Generating Reports Press the REPORT button on the View Results screen to open the Report Output screen (as shown below). Generate report When you press the REPORT button on the right side of the screen, a dialog box will appear asking you to enter the storage location and file name of the PDF file. Enter the information, and save the file. The following items may be specified for PDF output.
The following items may be specified for JPG output. Item [JPG] SPEAKERLAYOUT [JPG] SPL MAP ALL [JPG] SPL MAP [Overall A-Weighted] [JPG] SPL MAP [Overall Flat] [JPG] SPL MAP [HIGH, 2 kHz-8 kHz] [JPG] SPL MAP [MID, 500 Hz-2 kHz] [JPG] SPL MAP [LOW, 125 Hz-500 Hz] Output Outputs the speaker layout diagrams from the report (top view, side view) to a JPEG image. Outputs all sound pressure map diagrams to a JPEG image.
