There are several layout strategies possible within the source controllers, from simply placing one array or stack in the 3D View (Mono – which is the default arrangement) through to more complex shapes like ellipses and rectangles. Each have their own set of controls, together with some controls common to all layouts. The different layout strategies are discussed below:
This is the default arrangement. This places one array or stack at the origin.
This arrangement places two arrays or stacks symmetrically along the X-Axis. The placement on the X-Axis is defined by the X-Axis origin.
- Straight Line
The Straight Line arrangement places ‘X’ amounts of arrays or stacks along a line defined by the ‘line width’ parameter. This can be useful for front fills.
The Circle/Ellipse arrangement places ‘X’ amounts of arrays or stack about a circular / elliptical path defined by the ‘Size X’, ‘Size Y’ and ‘Sector Angle’ parameters.
The Arc arrangement places ‘X’ amounts of arrays or stacks about an arc path defined by the ‘Chord Length’ and ‘Angle’ parameters.
- Sub Arc
The Sub Arc arrangement is unique to the HSA Controller, and places ‘X’ amounts of subwoofers about an arc path defined by the ‘Line Width’ parameter. It also includes a beamsteering delay calculator to create broadside arrays.
Mechanical Angle: The mechanical angle parameter adds a progressive taper of physical displacement to the outer stacks of subwoofers with regards to the inner subwoofers within the array to create a beam-widening effect.
Electronic Angle: The electronic angle parameter adds a progressive taper of delay to the outer stacks of subwoofers with regards to the inner subwoofers within the array to create a beam-widening effect.
Beamsteering Angle: The beamsteering angle parameter adds a progressive taper of delay from one side of the subwoofer array to the other, to ‘steer’ the subwoofer energy from one side to another.
Note - with all adjustments of delay to the subwoofers within the HSA, be it through the electronic angle or beamsteering angle, care should be taken to ‘keep it sounding good’. It is very easy to place far too much delay on the outer subwoofers in the line, and see the mapping improve on the screen, but the real-world impact will be lost and turn into an apparent ‘smear’ of sub / low energy in reality. As a rough ‘rule of thumb’ - If the outer subwoofers are set to a delay time more than 5 or 6 milliseconds compared to the inner subwoofers, you should pay particular attention to what the array sounds like in reality.
The rectangle arrangement places ‘X’ amounts of arrays or stacks about a square or rectangular path defined by the Size ‘X’ & ‘Size Y’ parameters.
