CHAPTER 5

The block diagram below (Figure 5.3) shows one method of driving this example array, along with subwoofers (not in the MAPP Online Pro predictions).

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 other relevant factors should always be uniquely weighed into your own applications on a project basis.

USING M’ELODIE AS SIDEFILL OR DOWNFILL WITH MICA CURVILINEAR ARRAYS

The M’elodie loudspeaker’s acoustical characteristics promote seamless integration with MICA when used as downfill in MICA curvilinear arrays (via the MTF-MICA/ M’elodie transition frame), as well as when M’elodie arrays are being used as sidefills along with MICA main arrays. Understanding the differences and similarities between the two loudspeakers is very important for designing and for fine-tuning system coverage.

For a combined MICA/M’elodie array, the design will be dependent on three factors:

■Number and Type of Array Elements. Determining the number of elements of each type to use is critical. The number of elements drastically affects the uniformity of coverage of both SPL and frequency response. The number of longer-throw, higher SPL elements (MICA) and downfill (M’elodie) needs to be carefully selected.

■Vertical Splay Angles. Changing the splay angles between cabinets has a significant impact on vertical coverage, with the result that narrower vertical splay angles produce a higher Q vertical beamwidth and longer throw in the top elements (MICA), while wider splay lowers the Q at high frequencies for coverage on the lower elements (M’elodie).

■Horizontal Coverage. The horizontal coverage of the MICA and M’elodie sections can be considered fairly constant, regardless of the number of array elements on each section or the angles between them.
