YAMAHA VS Series Software

Commercial Installation Solutions Speaker Calculator (CISSCA) is a software application that quickly calculates the number of speakers required for optimum performance in a room specified by the user, plus the effective sound pressure level of the system. The user specifies the room size, type of speakers to be used, and speaker layout.

A fast, easy way to estimate the number of speakers required for any project.

Easy setup and operation.

Report output function provides convenient documentation for system proposals.

* Where more detailed information is required use the Yamaha Y-S3 Sound System Simulator application.

Supported Speakers(V2.09)

How to use

STEP1	STEP2	STEP3	STEP4

Enter the size of the room and the height of the listeners’ ears.	Select the target sound pressure level and the type of speakers to be used.	Specify a speaker system layout. An estimate of the number of ceiling speakers required for the project will be provided, plus surface mount speakers and subwoofers that can be positioned as required.	Check the difference between the effective sound pressure level of the estimated system and the target sound pressure level entered in STEP 2. Click the “REPORT” button to output the results in report form.

Speaker System Design Points

Achieving consistent sound pressure level at the listening plane (the average height of the listeners’ ears) is an important goal in speaker system design. The following points should be kept in mind.

Ceiling Speakers

It is important to note that the nominal coverage angle listed in ceiling speaker specifications is not the same as the speaker’s actual effective coverage angle. SPL at the nominal coverage angle is 6dB lower than the on-axis SPL, measured at a constant distance from the speaker. The effective coverage angle is defined as the angle at which the SPL is 6dB lower than the on-axis SPL at the listening plane. The effective coverage angle is usually about 70~80% of the nominal coverage angle. CISSCA calculations are based on effective coverage angles.

Maximum Overlap	Minimum Overlap	Edge-to-Edge	1.4 x Edge-to-Edge	2.0 x Edge-to-Edge

In a maximum overlap layout the -6 dB SPL point of one speaker is aligned with the axis of the adjacent speaker. This approach requires a larger number of speakers, but results in optimum overall performance in applications that depend on high sound pressure levels.	Edge-to-edge speaker layouts can result in gaps in the coverage. A minimum overlap approach is recommended to effectively eliminate coverage gaps.	Yamaha mostly recommends a Edge-to-edge layout, which is a commonly used configuration that aligns the -6 dB points of adjacent speakers. All Yamaha ceiling speakers supported by the CISSCA have a great advantage in this layout.	In this configuration speakers are spaced 1.4 times further apart than in the standard Edge-to-Edge layout. This makes it possible to reduce the number of speakers used, resulting in a more economical system which Yamaha can recommend.	The speakers are spaced 2 times further apart than in the standard Edge-to-Edge layout. This is the most economical approach, but it can result in uneven sound pressure level throughout the listening area.

Surface Mount Speakers

Uniform sound pressure level can easily be achieved throughout the listening plane with speakers that include by aligning the speaker's axis with the head of the most distant target (listener). This works because of the relationship between distance and coverage angle. When the perpendicular axis is aligned with the last row, the natural distance attenuation at the last row and the off-axis attenuation at closer rows tend to result in uniform SPL distribution. CISSCA allows fine adjustment of surface mount speaker tilt angle for maximum system design flexibility.
