After Auto Tuning
Setting methods
• Y-S3 sets speaker parameters for each speaker array.
• Y-S3 decides the speaker angles (Pan, Tilt and Splay Angle) to minimize the standard deviation of the sound
pressure level within the area that is selected by the user as the coverage of the speaker array.
• When computing angles, the proper setting is selected from among the conditions in which all of the target points
of the speaker composing the speaker array are within the selected cover area.
• Y-S
3
decides the EQ and gain for each speaker so that the frequency responses are flat and their levels match the
required SPL set by the user at the target points of each speaker that composes the speaker array. (Note 1: In
auto tuning, since sound pressure level calculations at axis points are computed based on the summing of energy,
peaks/dips from interference are not corrected. Note 2: Delay is not tuned automatically. All the delays are set to
0 ms after auto tuning.)
• In the level adjusting, Y-S
3
first decides the necessary output power for each speaker referring to the required SPL.
Then, Y-S
3
decides the attenuation level to adjust the necessary power difference between the speakers in one
speaker array. Finally, Y-S
3
decides the input signal level from the necessary output power and amplifier gain.
