Q. The cabinet rays are spaced further apart in the 45 – 75m area. Surely this

means that just one cabinet is covering more than fifteen meters of the audience?

A. The rays shown on ViewPoint

can be a little misleading because a series of

rays arriving at a shallow angle will appear to be widely spaced.

Many users equate this with the sun’s rays which weaken as the sun sets. In fact, the

setting sun’s power weakens due to greater absorption of shorter wavelengths through

the earth’s curved atmosphere not because the rays are arriving at a shallow angle.

With W8L Series arrays, the sound pressure level at any point in the room can be

thought of as the vector sum of all the cabinets +/-7.5 degrees from that point, not

simply due to the cabinet whose ray is aiming there. The example above shows that

the “cabinet 7” area receives contributions from cabinets 3 to 11, not just cabinet 7.

ViewPoint

’s Progressive Curvature calculations ensure that inter-cabinet splay

angles increase gradually from the array and arrays are driven slightly harder towards

the top of the array to partially compensate for air losses. This combination of

Progressive Curvature and Band Zoning gives maximum projection to the furthest

seats and the smoothest coverage.
