Array Types These arrays, while slightly larger than the conventional large-format VT4889 line arrays, provide improved horizontal pattern control, better off-axis performance, a choice of horizontal patterns, and increased sound pressure levels. The modules are built with common horizontal dimensions so that different models may be combined into a single array. This allows the designer the flexibility to vary the horizontal pattern throughout the array, or to change power levels by selecting either the standard version or the high-output versions as required. The maximum articulation angle is 4 degrees for the JBL VLA301, 8 degrees for the JBL VLA601, and 10 degrees for the JBL VLA901.
