CHAPTER 4

Figures 4.1 shows a series of MAPP Online predictions based on an example M2D system design. In this case, small vertical splay angles on the upper part of the array are used to cover longer distances, while greater angles are used in the lower elements to increase vertical coverage for shorter distances.

The block diagram (Figure 4.2) shows one method of driving this example array, along with additional fill loudspeakers and subwoofers (not in the MAPP Online predictions). Equalizers for each zone, as well as digital delays, provide a time adjustment to compensate for the various sub-systems if they are geometrically out of plane.

CAUTION: This example is not meant to be used as a template for your own system

designs. Acoustical characteristics, physical constraints, audio content, audience, and a slew of other factors should always be uniquely weighed into your own applications on a per-project basis.

	USING THE M2D-SUB WITH THE M2D
	The M2D provides full bandwidth frequency response down
	to 60 Hz, however, if the application or the program content
	requires additional low-frequency energy (e.g., clubs,
	discos, reinforcement of popular music), the M2D-Sub is
	naturally the best way to augment your M2D system. The
	M2D-Sub can achieve frequency response down to 30 Hz,
	extending system response appreciably and increasing the
