• Project

Enter the details of your project. Note that when exporting the results as a Project Report, the following characters are

automatically replaced with “_” (underscore) in order to prevent false representation in HTML format.

Characters: < > & “

• Calculation

Atmospheric Condition

Enter “Humidity” and “Temperature”. These parameters affect the speed of sound and the air absorption coefficient. The default

settings are 50% for humidity and 20°C for temperature. Check the “Air Absorption” checkbox to take attenuation of high

frequency components due air absorption into account in calculations.

Precision

Select the degree of precision used in the SPL calculation and contour calculation respectively. When a lower precision is

selected, Y-S3 uses an interpolation for faster processing. You may use a lower precision in the design stage for faster processing

and the highest precision in the final stage for checking the detailed results.

Phase Consideration

Check the “Interference Sum” checkbox to take phase interference into account when calculating the frequency characteristics

and sound pressure distribution. Energy summing calculations are performed if you do NOT check this box.

Sound Source for Calculation

Select “Swept Band Noise” or “Full Band Noise” for use as the sound source in the calculation. When “Swept Band Noise” is

selected, band pass noise assumed to be used. The bandwidth corresponds to the frequency selected in Aspect View. In this mode,

the overall level in Graph is the average energy of each band response. When “Full Band Noise” is selected, full band noise is

assumed to be used. The overall level in Graph is the summation of each band response. The “Swept Band Noise” mode is

convenient when you want to see the frequency characteristic while referring to the required SPL. You may easily deduce the

overall SPL by averaging the SPL results at several frequencies in this “Swept Band Noise” mode. The “Full Band Noise” mode

is more reasonable for a comparison of the calculated SPL with the value measured by using full band pink noise and real time

spectrum analysis.

Fig: Level difference between “Sound Source for Calculation” settings

Swept Band Noise Full Band Noise

Graph Overall

Select the frequency range of overall level displayed in Graph. The default range is 20 Hz to 20 kHz. For “Swept Band Nose” (cf.

previous section), the overall level denotes the average level of the response in the selected range. For “Full Band Noise”, the

overall level equals the summation of the response in the selected range. Check “A Weighted” checkbox to process the sound in a

similar manner to that of the human ear, using “A” characteristics. The Overall figures in Graph are displayed in dBA units.

Peak Factor of Source Signal

Select the source type from “Sine (Peak-to-RMS 3dB)”, “Pink (Peak-to-RMS 6dB)”, or “Music (Peak-to-RMS 10dB)”. “Sine”

has a 3 dB difference between the peak signal and RMS, “Pink” has 6 dB and “Music” has 10 dB. In this list, you select a

peak-to-RMS level in a practical sense. These levels are used by the clip level indicator and for auto tuning. “Output

Unit

Select “Imperial” (feet and Fahrenheit) or “Metric” (meter and Celsius) for units of length and temperature.

Listen

Enter the coordinates of the principal performer or person speaking. These figures should be absolute coordinates. You should

take height into account if you are using the equipment on a stage. For example, using a sound source 1.5 m for the stage floor,

when the height of the stage floor is 0.8 m from the ground gives a total height of 2.3 m. Y-S

3

refers to the origin point when

creating auralization data. The auralization data is calculated using head-related transfer functions (HRTF) by assuming that the

listener is facing the Origin Point. See chapter 6 for how to create auralization data.

Contour Display

Check the “Wall” checkbox to show the walls in Aspect View. The height of the wall is fixed at 5 m. You may check any

unnecessary radiation onto the walls by checking the contour shown on the walls. Note that Y-S

3

does not calculate the

reflections from the walls even if this option is selected.

• Overview

Place the speakers in the room. You can add positions for each speaker array on a conventional proscenium or stage, and place

speakers on flat surfaces within the room such as ceilings and walls.

• Installing Speakers

By installing the speaker data that you’ve downloaded from the Yamaha Pro Audio website, you will be able to add the speakers

you want to use to Y-S

3

. For the installation procedure, see “Installing Speaker Data” on page 4.

• Adding a new speaker (Add Speakers)

Click in Speaker List or select [Add New Array (N)] from the [Array (A)] menu to open the Add Speakers

window. You can select the installation method (Enclosure type - Manual layout, Enclosure type - Auto layout, Distributed) from

the list box. Place each speaker array for which you have entered details. Installed speakers will be appear in Aspect View, and

are available for selection in Speaker List. See chapter 6 for details on calculation results.

Speaker Arrays

This is a very flexible installation method compatible with all Installation Series speakers. You can save installation data for each

speaker array.

(See chapter 5)

Enclosure type - Manual layout:

The method allows a great deal of freedom in speaker layout, allowing the “Array Type” selection, mirroring, and direct entry of

coordinates.

Enclosure type - Auto layout:

Y-S

3

will select an appropriate speaker array for your room and arrange them automatically, based on your “System Type”

selection.

Distributed Speakers

You can arrange speakers with a fixed spacing on a level surface (e.g. wall or ceiling). For the compatible speakers, please check

the website at http://www.yamahaproaudio.com. Since the speakers will be treated as part of the flat surface, you cannot save this

arrangement.

(See chapter 5)

Distributed:

Sets the parameters for the level surface in which speakers are placed, depending on your speaker and the “Plane Type”

selections.

Coverage:

Y-S

3

automatically places speakers in the coverage area on the receiving surface, depending on your selections for placement

pattern and degree of consolidation of the receiving surface.

Grid:

You can place speakers at any intervals on a grid, based on your selections for placement pattern and the distance between

speakers.
